IBM Unveils World's First built-in Quantum Computing system for industrial consume | killexams.com true Questions and Pass4sure dumps

IBM to Open Quantum Computation core for industrial consumers in Poughkeepsie, unusual york

YORKTOWN HEIGHTS, N.Y., Jan. 8, 2019 /PRNewswire/ -- at the 2019 client Electronics flaunt (CES), IBM (NYSE: IBM) today unveiled IBM Q device One™, the world's first built-in widely wide-spread approximate quantum computing outfit designed for scientific and industrial use. IBM additionally introduced plans to open its first IBM Q Quantum Computation middle for industrial shoppers in Poughkeepsie, ny in 2019.

IBM Q methods are designed to sooner or later tackle complications that are presently viewed as too advanced and exponential in nature for classical techniques to handle. Future purposes of quantum computing may furthermore encompass finding unusual ways to model fiscal facts and isolating key international risk factors to create more suitable investments, or discovering the choicest direction across international techniques for ultra-productive logistics and optimizing fleet operations for deliveries.

Designed by using IBM scientists, systems engineers and industrial designers, IBM Q system One has an advanced, modular and compact design optimized for balance, reliability and constant trade use. For the primary time ever, IBM Q outfit One permits accepted approximate superconducting quantum computer systems to duty beyond the confines of the analysis lab.

tons as classical computers coalesce assorted add-ons into an built-in structure optimized to work collectively, IBM is applying the identical route to quantum computing with the first integrated commonplace quantum computing system. IBM Q outfit One is created from a brace of customized components that work collectively to serve because the most superior cloud-primarily based quantum computing application purchasable, together with:

  • Quantum hardware designed to live stable and auto-calibrated to supply repeatable and predictable exceptional qubits;
  • Cryogenic engineering that grants a constant bloodless and isolated quantum environment;
  • excessive precision electronics in compact kind components to tightly wield great numbers of qubits;
  • Quantum firmware to manage the system health and enable gadget upgrades with out downtime for clients; and
  • Classical computation to supply relaxed cloud entry and hybrid execution of quantum algorithms.
  • The IBM Q Quantum Computation center

    The IBM Q Quantum Computation middle opening later this 12 months in Poughkeepsie, unusual york, will expand the IBM Q community commercial quantum computing software, which already comprises methods at the Thomas J. Watson research core in Yorktown, stout apple. This unusual hub will house some of the world's most advanced cloud-primarily based quantum computing methods, which can live accessible to individuals of the IBM Q network, a global group of leading Fortune 500 businesses, startups, academic associations, and national analysis labs working with IBM to advance quantum computing and determine useful functions for company and science.

    IBM Poughkeepsie's pleasing history in computing stretches back to the pile of IBM's first line of construction company computer systems in the Nineteen Fifties, the IBM 700 sequence, and the IBM equipment/360 in the 1960s, which revolutionized the world via changing the route agencies concept about computer hardware. Now home to one of the world's most-potent classical system, the IBM mainframe, IBM Poughkeepsie is placed to be some of the few places on this planet with the technical capabilities, infrastructure and handicap to dash a quantum computation core, together with access to lofty efficiency computing systems and a lofty availability data core obligatory to work alongside quantum computer systems.

    "The IBM Q gadget One is an immense step ahead in the commercialization of quantum computing," spoke of Arvind Krishna, senior vice president of Hybrid Cloud and director of IBM research. "This unusual outfit is well-known in expanding quantum computing beyond the walls of the analysis lab as they work to develop practical quantum applications for company and science."

    Designing a primary: IBM Q system One

    IBM assembled a global-class team of industrial designers, architects, and manufacturers to work alongside IBM analysis scientists and methods engineers to design IBM Q system One, together with UK industrial and indoors design studios Map project workplace and habitual Design Studio, and Goppion, a Milan-based mostly company of high-end museum screen situations that offer protection to one of the vital world's Most worthy artwork including the Mona Lisa at the Louvre, and the Crown Jewels at the Tower of London.

    together these collaborators designed the first quantum gadget to consolidate hundreds of components into a pitcher-enclosed, air-tight environment developed peculiarly for company use, a milestone in the evolution of trade quantum computers.

    This integrated system aims to wield one of the vital difficult elements of quantum computing: constantly keeping the fine of qubits used to operate quantum computations. potent yet gentle, qubits quickly lose their special quantum homes, usually within one hundred microseconds (for state-of-the-art superconducting qubits), due in portion to the interconnected machinery's ambient din of vibrations, temperature fluctuations, and electromagnetic waves. protection from this interference is one in every of many the explanation why quantum computers and their accessories require watchful engineering and isolation.

    Story continues

    The design of IBM Q device One includes a nine-foot-tall, 9-foot-vast case of half-inch thick borosilicate glass forming a sealed, airtight enclosure that opens easily using "roto-translation," a motor-driven rotation round two displaced axes engineered to simplify the device's renovation and help procedure whereas minimizing downtime – an extra ingenious trait that makes the IBM Q gadget One preempt to reputable commercial use.

    A string of impartial aluminum and metal frames unify, however furthermore decouple the gadget's cryostat, wield electronics, and exterior casing, helping to tarry away from capabilities vibration interference that leads to "phase jitter" and qubit decoherence.  

    a replica of IBM Q system One will live on screen at CES. For extra tips talk over with, here.

    This unusual outfit marks the subsequent evolution of IBM Q, the business's first effort to interpose the general public to programmable generic quantum computing during the cloud-based mostly IBM Q journey, and the trade IBM Q network platform for enterprise and science applications. The free and publicly attainable IBM Q experience has been continuously operating considering may of 2016 and now boasts more than one hundred,000 users, who maintain dash more than 6.7 million experiments and published greater than 130 third-party research papers. builders maintain additionally downloaded Qiskit, a full-stack, open-supply quantum application pile equipment, greater than 140,000 instances to create and dash quantum computing programs. The IBM Q community includes the recent additions of Argonne national Laboratory, CERN, ExxonMobil, Fermilab, and Lawrence Berkeley country wide Laboratory.

    energy programs retain growing to live To conclude Off 2018 | killexams.com true Questions and Pass4sure dumps

    January 28, 2019 Timothy Prickett Morgan

    The vim programs line, buoyed by means of the carry of excessive-end energy E980 systems for great AIX and IBM i jobs, a even movement of IBM i device upgrades, and a few traction in vigour-based mostly Linux clusters for HPC and information analytics workloads, turned in a noble looking noble remaining quarter for 2018, and capped three prior quarters of augment throughout 2018 to flaunt in a replete 12 months of increase.

    which you can’t command how a lot boom, of path, but within the lead yarn of this challenge of The 4 Hundred, I took my most desirable stab at modeling the quarterly revenue trek of the vim techniques line given that the soar of 2018, and in keeping with that model, I reckon that the vigour techniques line booked only a tad over $1.6 billion in sales, up 8.8 percent compared to 2017’s figures and marking the primary year of boom due to the fact 2011 and probably the most stagy growth they now maintain probably viewed in an dreadful lot longer.

    Jim Kavanaugh, IBM’s chief economic officer, talked in short with Wall highway analysts about how the energy techniques line did in q4 2018. “vigor salary become up 10 p.c, pushed by route of Linux and continued robust adoption throughout their unusual Power9-primarily based architecture,” Kavanaugh referred to. “in the fourth quarter, they achieved the free up of their subsequent era Power9 processors in the extreme conclusion, and they had stout adoption in both the low and high-conclusion techniques. Their Power9 programs are designed for managing superior analytics, cloud environments, and data intensive workloads in AI, SAP HANA, and Unix markets and they now maintain extended HANA certification to their Power9 extreme end. within the fourth quarter, they had powerful initial traction with their unusual choices that optimize both hardware and application for AI, similar to PowerAI vision, which they delivered in the 2d half of 2018. And they maintain virtually completed the deployment of their supercomputers at the U.S. arm of power labs within the quarter.”

    That changed into a $325 million deal, which IBM has been booking total the route through 2018 as machines rolled in and the “Summit” desktop at o.k.Ridge countrywide Laboratory and the “Sierra” machine at Lawrence Livermore country wide Laboratory handed degrees of qualification tests.

    What they might in fact want to understand is how 2019 is asking, and this is total Kavanaugh had to interpret when poked that query: “We continue to bring unusual innovation to market to deliver value for their clients in their Power9 structure, which is resonating well in the industry. And they received majestic acceptance, and grew 10 percent within the fourth quarter. They forecast to live able to continue to play out in 2019. So they now maintain bought a majestic ebook of company perquisite here and some tailwinds at us.”

    Tailwinds are total the time respectable, in case you are attempting to create up for misplaced time in specific, so that’s decent.

    So how did the leisure of huge Blue fare? Let’s prefer a look. within the closing quarter of 2018, IBM’s revenues dipped by route of 3.5 % to $2176 billion and net profits became $1.95 billion, which turned into twice as great in magnitude as the loss that IBM reported in this Fall 2017 as a result of some write-offs. IBM pushed $2.sixty two billion in system and storage hardware and operating systems to exterior purchasers in the fourth quarter, down 21.three p.c, plus yet another $238 million in iron to different IBM gadgets. IBM had $551 million in pre-tax revenue for the combined internal and external revenue, which become 19.3 percent of revenue. My ultimate guess, considering the fact that IBM doesn’t provide out precise numbers, is that IBM sold $2.17 billion in hardware (servers and storage) plus an additional $447 million in working techniques.

    in the event you add total of the basis working device, middleware, database, programming equipment, tech assist, and financing on proper of the outfit z and energy methods traces, plus external disk, flash, and tape storage, IBM has quite an superb business. a noble deal better than the gadget hardware and working system figures that it reports on a quarterly basis to Wall street. here is the breakdown of IBM’s revenue throughout its divisions, which is the soar factor for estimating IBM’s proper and actual systems business:

    From this, I drill down into every division and rate how a majestic deal of each division’s revenue is chiefly for IBM’s own system z and power methods structures and the connected storage product revenue. in case you create some guesses – and i should, as can they total outside of the company – then a suppose for the proper programs company emerges. And this doesn't encompass compute, storage, and networking means sold on the IBM Cloud, which is a further animal utterly.

    Suffice it to assert that this is an attractive gigantic trade certainly, with unseemly profits throughout the mixed platforms that are in the latitude of 55 % to 60 % of revenues usually. here is relatively respectable, and is a plenty stronger programs trade than IBM itself talks about. in the fourth quarter, I reckon that this company definitely declined via 11 percent or so, to $7.41 billion, however that changed into mainly due to the gadget z14 mainframe help cycle running its path after five quarters of income. IBM spoke of in its record that system z revenues were down 44 p.c 12 months-on-yr within the fourth quarter at regular forex, and that truly harm. power techniques sales cannot, as yet, create up the change.

    That stated, power methods income are on the upward push, and maintain tremendous prospects in HPC, records analytics, computer learning. in-memory processing, and different advanced workloads as smartly because the consistent freddy ERP purposes that maintain been on IBM i and AIX systems for many years. it's difficult to assume about that IBM can push revenue up as lofty as they had been lower back in 2010 through 2012, but it surely can obtain some of the route returned there. One other component: I don't maintain any conception what energy systems operating IBM i earnings are, however what I achieve understand is that IBM i income maintain been riding salary augment total the route through 2018, and when you add in the software, services, and financing atop of this, here's nevertheless a fairly great and in reality ecocnomic enterprise. Which is a pretty noble component for the long-time period possibilities of IBM i.

    In many cases, the unapproved operating systems are the so-called open-source systems, which advance with total of the source code, so that a programmer can rewrite them as much as he wants. These versions, with names dote Debian GNU/Linux, FreeBSD or Red Hat Linux, are produced by loosely knit groups of programmers who contribute their code into a vast commonwealth of software that can live freely shared. The members contribute what they can and maintain the license to help the code.

    At first glance, many information technology managers from traditional backgrounds recoil in horror at the thought of open-source operating systems. The freewheeling exchange of source code seems dote a recipe for total chaos, and every IT manager knows that preventing chaos is the most well-known portion of the job. No one ever got fired for buying from Microsoft Corp., IBM or Sun Microsystems Inc.

    Some programmers, however, esteem the open-source systems. They advance with total the source code, which often means less cursing at a black box. Talented programmers with a noble scholarship of open-source systems can often finish jobs much faster.

    Consider an engineer I'll muster "Bob." He's an open-source smuggler. His boss wanted first and foremost to withhold the networks running and the file servers serving. His boss believed that the best route to accomplish this was to pay one company to provide order. You obtain what you pay for, he assumed, and one route to obtain a lot is to pay a lot.

    Bob's problem was simple. One of the company's newly acquired arm offices ran Windows NT and some custom software that was hard-wired to work with the old-fashioned network. The unusual bosses insisted that Bob integrate the existing network with the new, incompatible network that had its offices in another state. Bob considered doing the job the official way. He calculated the hours, weighed the amount of red tape required to reinstall, figured out the travel time and then considered whether it was even workable to rewrite the software. The potential bill skyrocketed.

    Then he had an idea. He grabbed an obsolete 50-MHz 486-based PC and installed FreeBSD on it. This Linux cousin is well-known and loved in the networking community because it's a descendant of the Berkeley Software Distribution (BSD) versions of Unix that formed the original backbone of the Internet. In fact, most Internet software was originally conceived of on machines running BSD, so it's often the most compatible operating system for Internet applications. A few days later, the old, previously discarded computer was up and running, translating the data from one system to the other and gluing the two networks together.

    "It took about four days because I'm so behind at FreeBSD," Bob says, "but I could now redo the entire thing if I had to in just one afternoon."

    Politically reform PCs

    Bob's yarn is a elated one. The low cost pleased his boss, and no one looked too closely at the guts of his "NT-compatible" router. The boss apparently preferred to concentrate on the expense tag.

    Unfortunately, many programmers are in situations dote Bob's. IT departments pan endless problems just keeping their data synchronized and their computers working smoothly. Everyone knows that stout rules dote "Always buy Microsoft" often create life a bit simpler. But everyone furthermore knows that it sometimes just makes noble sense to crash the rules.

    The world of operating systems may seem dote a placid environment where total the blood was shed years ago when Microsoft achieved its final dominance. That's what many managers want their IT staffs to believe: Microsoft on total machines means harmony everywhere.

    But sometimes the perquisite implement isn't made by Microsoft, IBM or whoever the dominant player happens to be. Increasingly, engineers are turning to open-source operating systems because having the source code lets them customize their work and decipher the difficult problems.

    Another anonymous programmer reports that he got involved in a duel with a vie arm in his company that protested when it institute out he was using the security-conscious OpenBSD operating system to process credit-card transactions.

    "(The leader of that branch) wasn't elated and was determined to conquer us, so he decided to start a part e-commerce organization that they would maintain no input into which would (have been) based entirely around Windows NT 4.0," he says. "That was in September. (Their system) quiet doesn't work. But the BSD kit on the other side of the company has been handling credit-card transactions securely since October."

    The perquisite implement for the job

    There are plenty of other success stories out there on the Net. Many of the contributors to open-source systems interpret the tools are more springy and easier to adjust to complicated tasks. This feature is especially valuable when the engineers are called upon to bear unusual applications or offer unusual services over the Internet. When the machines start working successfully, the smart manager doesn't inquire too often or too closely about the operating system vendor.

    The success stories can live institute in some deviant places. The TiVo television recorder is a kind of digital VCR that stores MPEG-encoded versions of television programs on its difficult disk. The system comes with a number of unusual features, such as an "instant replay" that quickly jumps back seven seconds.

    Underneath the user interface is the Linux operating system. TiVo Inc. in Sunnyvale, Calif., customized the operating system to hurry up the real-time tasks it needed and started shipping Linux deeply embedded in the box. The TiVo user is nonexistent the wiser, because total the Linux calls are hidden from view.

    The programmers involved usually cite two reasons for their success. First, the source code makes it easier for them to tweak, revise or extend the operating system. While companies dote Microsoft or Sun create it workable to extend their operating systems, they often withhold some of the information secret to maintain their leverage.

    And because the Internet was originally built on machines running BSD, the basic protocols were specified, prototyped and finalized in that environment. Therefore, it's just easier to create unusual Internet applications using the original article.

    That compatibility is one intuition why Apple Computer Inc. is rewriting its Mac OS operating system to incorporate much of the code from the open-source community's FreeBSD and NetBSD. The core, which the company calls Darwin, is furthermore being shared with the world in the hope of making it easier for Macintosh customers to work with the systems. Still, Apple hasn't opened up total the forthcoming Mac OS X code. The slick user interface and many of the time-saving features that attract unusual users are being kept proprietary.

    IT professionals working with Mac OS X report mixed experiences. Those who consume only the open-source parts of Darwin interpret they indulge in the unusual opportunities. But those who necessity access to the portion that's quiet proprietary grouse about the restrictions.

    One anonymous programmer says his boss heard his pleas for an open-source operating system and suggested Mac OS X. Because it's both open-source and a product from a stout company, it has the aura of respectability and openness, he says. But in his case, the openness didn't help, and he ended up switching to FreeBSD.

    Many open-source operating systems create it simple to bare away total but their most necessary parts. This flexibility makes it workable to dash on less-expensive hardware and furthermore obtain the maximum performance out of high-end hardware. The extra layers of gloss that create systems dote Windows NT easier to understand can furthermore create them less efficient, because they obviate a systems administrator from stripping away unnecessary functions.

    "I reckon a PIII-450 properly configured with about 512MB of RAM will give me around a 400% to 500% performance augment over the incredibly expensive Sun hardware at around a tenth of the cost," says an engineer who supports open-source systems.

    Coping with configuration

    While many programmers are quite positive about open-source solutions, some are more circumspect. Rob Newberry, a programmer at Group Logic Inc. in Arlington, Va., has been an avid fan of Linux. Some of his networking code has, in fact, been made portion of the benchmark Linux kernel.

    Still, he says that his company is thinking seriously about converting its mail server back from Linux to Windows NT. Group Logic has documented several cases where the sendmail program running on the Linux server lost an e-mail message. While it's had few other problems with Linux, he says the software is quiet difficult for much of the staff to manage; Windows NT is just easier for most of them to consume and reconfigure. According to Newberry, saving the cost of a Windows NT license just isn't worth it.

    "Even though there are some of us here who respect Linux and work on Linux, they are rapidly trying to angle it out. It just kind of becomes a maintenance headache," he says. "We maintain lots of engineers here. There (are) only a few of us who know the Linux tricks." The folks who know Linux maintain better things to achieve than maintain the mail system, he notes.

    This outcome is leading some companies to roll the operating system into their product and sell the two as a pair. Network Flight Recorder Inc. in Rockville, Md., creates software that turns a PC into a spy that watches a network for suspicious activity. Abnormal data-flow patterns that might sneak by firewalls will set off warning bells when this device spots them.

    Naturally, the creators of the product want this system to live as secure as possible, so they turned to OpenBSD, a cousin of FreeBSD designed to eliminate security holes. They stripped out extra parts of the system and built a special version of the kernel that handles only their workload. They bundled total of this on a single, bootable CD-ROM that takes over the PC.

    Marcus Ranum, Network Flight Recorder's CEO, explains that the CD-ROM furthermore simplifies the technical support. The user can't change anything on the machine, so nothing can inadvertently live screwed up.

    "The CD-ROM has a bootstrap loader and a kernel and their own set of applications inside. There are no user services inside," he says. "There's nothing on this sucker except the one application. It takes about 12 minutes to install their product, and that's the time to boot up and autodetect."

    Ranum says hiding the operating system from everyone, including the professionals who know how to maintain one, is a smart solution. Every system takes time to learn, and his company wants to create its Network Flight Recorder product simple to use.

    Ranum says, "The Unix heads Hate NT, and the NT heads Hate Unix, so their retort is that it's dote a toaster: There are no user-serviceable parts inside."

    STORServer Joins Forces with IBM to assist Ease SMB Storage Woes

    New all-in-one backup, archive, and disaster-recovery appliances approved as “Built on IBM Express” offerings

    Colorado Springs, CO -- April 3, 2006 -- STORServer®, manufacturer of the all-in-one suite of trade Continuity Appliances, announces a unusual line of STORServer EZ Backup Appliances®. These cost-effective, easy-to-use backup solutions, which are preloaded with IBM storage software and hardware, are designed to assist minute to medium size businesses (SMBs) manage their data.

    “SMBs are a fast-growing and often-underserved market, especially in terms of backup and calamity recovery,” said Ellen Rome, STORServer vice president of sales and marketing. “Our unusual EZ Backup Appliance bundles IBM’s leading hardware and software technology to provide an affordable, trustworthy solution that is easy to implement and maintain while providing a sophisticated feature set preempt to SMBs’ growing needs.”

    The unusual line of EZ Backup Appliances, available in both entry-level and high-end scalable models, are efficient storage solutions for SMBs that typically maintain smaller budgets and fewer employees armed with the necessary skills to deal with complicated IT management issues. Pre-configured with hardware and software necessary for backup, archiving, and calamity recovery, the appliance contains IBM’s latest in data-protection technologies, including disk and tape storage such as the unusual IBM TotalStorage TS3310 Tape Library.

    The STORServer EZ Backup Appliance leverages IBM Tivoli Storage Manager, enterprise-level backup and recovery software, and is offered in three pre-configured bundles: Disk-to-Disk, which offers backup and archives with optional tape or disk for calamity recovery; Disk-to-Tape, with backup, archives, an online tape pool and calamity recovery to tape; and Disk-to-Disk-to-Tape, which offers backup, archives, an online pool of IBM TotalStorage DS4100 disk arrays, and calamity recovery to tape.

    Fully automated, policy-based configurations are available for customers storing total amounts of data, from less than one terabyte to up to 10 terabytes for a lone appliance. Multiple appliances can live installed and managed from one interface for customers that maintain more data or that necessity to ration their recovery storage management. Each appliance comes with a 3-year warranty that provides a lone point of contact for technical support.

    Backup and calamity recovery is a top concern for SMBs and great organizations alike, according to Enterprise Strategy Group (ESG) analyst Heidi Biggar. She credits STORServer with creating a solution for SMBs that is both affordable and simple to manage.

    "The problem is SMBs generally lack the necessary resources -- people, dollars, and technology -- to assault the backup and recovery problem at its root,” Biggar said. “Historically, SMBs maintain either tried to 'fix' the problem with enterprise backup solutions (which tend to live too unwieldy and expensive for their needs) or maintain ignored the problem altogether. What SMBs want -- and necessity -- are easy-to-use, scalable, and integrated solutions. The STORServer Appliance fits this bill nicely and takes the guesswork out of data protection."

    Also announced today, STORServer’s EZ “Entry” Backup Appliance provides a low-cost, reliable, disk-to-disk backup solution for up to two terabytes of data. The EZ “Entry” Backup Appliance integrates IBM’s unusual Tivoli Storage Manager Express, automated backup and recovery software designed specifically for minute and mid-sized businesses. total backups are stored on the server disk and an optional disk array is available for expanded storage capacity. Customers can furthermore add tape backup for calamity recovery. Two scalable entry appliances are available -- one for customers with less than one terabyte of data and the other designed to accommodate up to two terabytes of storage.

    The entire line of EZ Backup Appliances back up total current servers and workstations and can furthermore live purchased with IBM Tivoli Continuous Data Protection for Files – software that is designed to continuously and instantaneously capture and rescue changes to files in true time and transmit copies of data to a backup location to add a second layer of defense against data loss.

    With the integration of IBM Express Portfolio software and hardware, the unusual STORServer EZ Backup Appliances maintain received “Built on IBM Express” validation. Built on IBM Express is an initiative designed to incorporate IBM Express products with IBM trade confederate products in order to provide integrated solutions that assist enable SMBs to manage their IT environments with the same capabilities as larger companies.

    The STORServer EZ Backup Appliances are available through IBM resellers only. Pricing for the entry-level appliance starts at $5,000 and the higher-end model begins at $15,000. For more information, visit http://www.storserver.com.


    Backup and Restore Technologies for Windows | killexams.com true questions and Pass4sure dumps

    This chapter is from the engage 

    Various types of backup schemes exist, and they can live categorized in different ways. In an actual data center, one typically uses multiple types of backups. In short, the categorization of backups should not live taken to live mutually exclusive. Backups can live classified on the basis of

  • Architecture

  • Functionality

  • Network infrastructure

  • Sections 5.3.1 through 5.3.3 prefer a glimpse at each of these types of classification.

    5.3.1 Backup Classifications Based on Architecture

    One route of classifying backups is based on the architecture. That is, backups are classified in terms of the objects they deal with and the amount of awareness the backup application has of these objects. The available types of architecture-based backups, described in Sections 5.3.1.1 through 5.3.1.3, are

    5.3.1.1 Image- or Block-Level Backup

    The backup application in this case deals with blocks of data. Typically, this kind of backup scheme needs total applications on the server to cease accessing the data that is being backed up. The application opens the disk to live backed up as a raw disk (ignoring the file locations) and literally does analytic block-level read and write operations.

    The advantages of this kind of backup are that the backup and restore operations are very fast, and it can live a noble calamity recovery solution. One drawback is that applications and even the operating system cannot access the disk while the backup or restore is happening. Another drawback is that image-level backups of a sparsely populated volume can result in a lot of unused analytic blocks being copied for the backup. Some backup applications provide the logic necessary to detect and skip unused analytic blocks. These are called sparse image backups.

    Finally, it is difficult to retrieve just a particular file or a few files rather than restore total the data to a disk. To achieve so, the restore software must understand the file system metadata as it exists on the tape, retrieve this metadata, and from there, compute the location on the tape where the data for the particular file resides. Some vendors provide the capacity to restore a particular file from an image-level backup, but these offerings are available on only inevitable operating system platforms and not others. Some restore applications achieve attempt to optimize restoring a file from an image-level backup. These applications write file metadata such as the file allocation table for FAT16 to the tape.

    The version of NTFS included with Windows 2000 already keeps total metadata in files—for example, the bit map that represents analytic block allocation. The restore application locates the required metadata. From this the software calculates the positions on tape of each of the required analytic data blocks for the file being restored. The tape is then spooled in one direction, and total the relevant portions of the tape are read while the tape is stirring in a lone direction, thus providing the file data for restoration. The tape is not moved forward and backward at all, so not only is the restore time reduced, but the life of the tape is extended as well. Legato Celestra is one example of such a backup application.

    Note that sometimes the altenative of backup is limited. regard the case in which a database uses a raw disk volume (without any kind of file system on that volume). In this case the only two choices are an image-level backup or an application-level backup (the latter is described in Section 5.3.1.3).

    5.3.1.2 File-Level Backup

    With this ilk of backup, the backup software makes consume of the server operating system and file system to back up files. One handicap is that a particular file or set of files can live restored relatively easily. Another is that the operating system and applications can continue to access files while the backup is being performed.

    There are several disadvantages as well. The backup can prefer longer, especially compared to an image-level backup. If a lot of minute files are backed up, the overhead of the operating system and file and directory metadata access can live high. furthermore the problem of open files described earlier exists and needs to live solved.

    Another drawback is related to security. This issue arises irrespective of whether the backup is made via a file-level backup or an image backup. The problem is that the restore is typically done through an administrator account or backup operator account rather than a user account. This is the only route to ensure that multiple files belonging to different users can live restored in a lone restore operation. The key is that the file metadata, such as access control and file ownership information, must live properly set. Addressing the problem requires some API back from the operating system and file system involved (NTFS) to allow the information to live set properly on a restore operation. In addition, of course, the restore application must create proper consume of the facility provided.

    5.3.1.3 Application-Level Backup

    In this case, backup and restore are done at the application level, typically an enterprise application level—for example, Microsoft SQL Server or Microsoft Exchange. The backup is accomplished via APIs provided by the application. Here the backup consists of a set of files and objects that together constitute a point-in-time view as determined by the application. The main problem is that the backup and restore operations are tightly associated with the application. If a unusual version of the application changes some APIs or functionality of an existing API, one must live watchful to obtain a unusual version of the backup/restore application.

    Applications either consume a raw disk that has no file system associated with the volume/partition or simply maintain a huge file allocated on disk and then lay down their own metadata within this file. A noble example of an application that takes this approach is Microsoft Exchange. Windows XP and Windows Server 2003 interpose an well-known feature in NTFS to facilitate restore operations for such files. The file can live restored via analytic blocks, and then the discontinuance of the file is marked by a unusual Win32 API called SetFileValidData.

    5.3.2 Backup Classifications Based on Functionality

    Yet another route of classifying backup applications is based on the functionality that is achieved in the backup process. Note that a data hub typically uses at least two and very often total types of the backups described in Sections 5.3.2.1 through 5.3.2.3: full, differential, and incremental.

    5.3.2.1 Full Backup

    In a replete backup, the complete set of files or objects and associated metadata is copied to the backup media. The handicap of having a replete backup is that only one media set is needed to recover everything in a calamity situation. The drawback is that the backup operation takes a long time because everything needs to live copied. replete backups are very often accomplished with the image- or block-level backup architecture.

    5.3.2.2 Differential Backup

    A differential backup archives total changes since the last replete backup. Because differential backups can live either image block based or file based, this set of changes would portray either the set of changed disk blocks (for image-based backup) or the set of changed files (for file-based backup). The main handicap of differential backup is that the backup takes a lot less time than a replete backup. On the other hand, the drawback is that recovering from a calamity takes longer. A calamity recovery operation involves running at least two restore operations, one corresponding to a replete backup and one corresponding to a differential backup.

    With low-end storage deployed, file-based differential backups are used when the applications by nature tend to create multiple minute files and change or create just a few of them since the last replete backup. In addition, when low-end storage is deployed, file-based differential backups are not typically used with database applications, because database applications, by their very nature, tend to create changes in minute parts of a huge database file. Hence a file-based backup would quiet maintain to copy the entire file. A noble example here is Microsoft Exchange, which tends to create changes in minute parts of a huge database file.

    Figure 03Figure 5.3  Direct-Attached Backup

    With high-end storage deployed, image-based differential backup can live used in any situation, including with database applications. The intuition for this flexibility is that the high-end storage units can track a lot of metadata and thus quickly identify which disk blocks maintain changed since the last replete backup. Thus, only this minute number of disk blocks needs live archived, and the great number of unchanged disk blocks that are present in the same database file can live ignored. Even though the backup with high-end storage is more efficient, APIs that start the backup at a consistent point and allow the I/O to resume after the backup has been accomplished are quiet needed. The efficiency of high-end storage simply minimizes the time during which total I/O must live frozen while the backup is being made.

    5.3.2.3 Incremental Backup

    An incremental backup archives only the changes since the last replete or incremental backup. Again, the obvious handicap is that this backup takes less time because items not modified since the last replete or incremental backup achieve not necessity to live copied to the backup media. The drawback is that a calamity recovery operation will prefer longer because restore operations must live done from multiple media sets, corresponding to the last replete backup followed by the various incremental backups.

    In the absence of high-end storage, file-based incremental backup is used only when a different set of files is typically created or modified. With high-end storage that can provide the required metadata tracking, block-based incremental backup may live used.

    5.3.3 -Backup Classifications Based on Network Infrastructure

    One route of classifying a backup scenario is based on the network topology used, and how that topology lends itself to achieving the best route for backing up the attached hosts. The network infrastructure–based backup types—direct-attached backup, network-attached backup, LAN-free backup, and server-free backup—are described in detail in Sections 5.3.3.1 through 5.3.3.4.

    5.3.3.1 Direct-Attached Backup

    Direct-attached backup was the first profile of backup used, simply because it emerged in the era when storage devices were typically attached directly to servers. Despite the advent of network storage, direct-attached backup remains a very current topology for backing up Windows-based servers. Direct-attached backup is illustrated in pattern 5.3.

    The handicap of direct-attached backup is that it is fairly simple. An application running on the server reads data from the preempt disk volume and writes it to the tape device. The biggest problems with direct-attached backup are these:

  • Tape devices are duplicated (one per server that needs backup), which is expensive. To retain it differently, sharing the tape device between servers is difficult.

  • The total cost of ownership is lofty because you necessity more administrators doing tape backups using multiple tape devices.

  • Storing multiple tapes can live confusing.

  • Because the data on different servers is often duplicated, but slightly out of sync, the tape media reflects duplication of data with enough seemingly similar data to cause confusion.

  • Last, but not least, the server must live able to wield the load of the read/write operations that it performs to stream the data from disk to tape.

  • 5.3.3.2 Network-Attached Backup

    As Chapter 3 discussed, the era of direct-attached storage was followed by the client/server era with a lot of clients and servers sharing resources on a LAN. This LAN environment facilitated the possibility of having a server on the LAN with a tape backup device that could live shared by total the servers on the LAN.

    Figure 5.4 shows a typical deployment scenario for network-attached backup. The left side of the diagram shows a brace of servers. These could live application or file-and-print servers, and there may live more than just a couple. The perquisite side of pattern 5.4 shows a backup server with a tape unit attached. This tape device can live used for backing up multiple file-and-print or application servers. Thus, network-attached backup allows a tape device to live shared for backing up multiple servers, which can reduce costs.

    Figure 4Figure 5.4 Network-Attached Backup

    The problems that network-attached backup introduced are these:

  • The backup operation consumes LAN bandwidth, often requiring watchful segmentation of the LAN to retain the backup traffic on a part LAN segment.

  • Host online hours (i.e., operating hours) increased; that is, the amount of time servers needed to live available for transactions and user access grew. In addition, the amount of data on the servers (that needed to live backed up) started increasing as well.

  • Increasingly, these problems led to the consume of backup requirements as the sole basis for network design, determining the exact number of backup devices needed, and the selection and placement of backup devices.

    5.3.3.3 LAN-Free Backup

    The advent of storage district networks introduced unusual concepts for backup operations. The unusual functionality is based on the fact that a storage district network (SAN) can provide a lofty bandwidth between any two devices and also, depending on the topology, can offer multiple simultaneous bandwidth capability between multiple pairs of devices with very low latencies. In contrast, using Fibre Channel loop topology with many devices—that is, more than approximately 30—cannot offer multiple simultaneous high-bandwidth connections with low latencies, because the total bandwidth of the loop must live shared among total attached devices.

    Figure 5.5 shows a typical SAN-based backup application. Note the FC bridge device in the figure. Most tape devices are quiet non-FC based (using parallel SCSI), so a bridge device is typically used. In this figure, the Windows NT servers maintain a presence on both the LAN as well as the SAN.

    Figure 5Figure 5.5 SAN-Based Backup

    The backup topology in pattern 5.5 has the following advantages:

  • The tape device can live located farther from the server being backed up. Tape devices are typically SCSI devices, although FC tape devices are now more readily available. This means that they can live attached to only a lone SCSI bus and are not shared easily among servers. The FC SAN, with its connectivity capability, neatly solves this problem. Note that one quiet needs a solution to ensure that the tape device is accessed properly and with preempt permissions. Here are some possibilities:

  • One solution is to consume zoning, allowing one server at a time to access the tape device. The problem with this solution is that zoning depends on noble citizen behavior; that is, it cannot ensure compliance. Another problem with zoning is that it will not ensure proper utilization of a tape changer or multitape device.

  • Another solution is to consume the SCSI Reserve and Release commands.

  • Yet another solution is to maintain the tape device connected to a server, allowing for sharing of the tape pool by having special software on this server. Sharing of a tape pool is highly attractive because tape devices are fairly costly. IBM's Tivoli is one example of a vendor that provides solutions allowing the sharing of tape resources.

  • The backup is now what is often referred to as a LAN-free backup because the backup data transfer load is placed on the SAN, lightening the load on the LAN. Thus, applications achieve not obtain bogged down with network bandwidth problems while a backup is happening.

  • LAN-free backup provides more efficient consume of resources by allowing tape drives to live shared.

  • LAN-free backup and restore are more resilient to errors because backups can now live done to multiple devices if one device has problems. By the same token, restores can live done from multiple devices, allowing more flexibility in resource scheduling.

  • Finally, the backup and restore operations typically complete a lot more quickly, simply because of the SAN's higher network speed.

  • 5.3.3.4 Server-Free Backup

    Server-free backup is furthermore sometimes referred to as serverless backup or even third-party copy. Note that server-free backup is furthermore usually LAN-free backup—LAN-free backup that furthermore removes the responsibility of file movement from the host that owns the data. The understanding is fairly simple, consisting of leveraging the Extended Copy SCSI commands.

    Server-free backup began as an initiative placed before the Storage Networking Industry Association (SNIA) that evolved into the SCSI Extended Copy commands ratified by the International Committee for Information Technology Standards (INCITS) T10 Technical Committee (ANSI INCITS.351:2001, SCSI Primary Commands-2). Note that SCSI already supported a copy command, but the problem was that total SCSI devices required attachment to the same SCSI bus to consume this command (the Copy command has since been made obsolete in the SCSI standards; note http://www.t10.org). The Extended Copy command adds features such that the data source and data destination may live on different SCSI buses and yet quiet live addressable because the syntax of the command allows for this.

    In server-free backup, the backup server can remain relatively free to wield other work while the actual backup is accomplished by the data mover agent. The data is moved directly from the data source to the destination (backup media) (instead of being moved from the source to the backup server to the destination).

    While appreciating the advantages of server-free backup, one should not forget that server-free restore is a very different issue. Server-free restore operations are quiet relatively rare; that is, backups made using server-free backup technology are very often restored via traditional restore technology that involves the consume of a backup software server.

    Server-free backup is illustrated in pattern 5.6. In the interest of simplicity, the pattern shows the minimum number of elements needed to debate server-free backup. In practice, however, SANs are much more complex. The pattern shows a Windows server connected to an FC switch via an FC HBA. An FC-to-SCSI router is furthermore present, to which are connected a SCSI tape subsystem and a disk device. The disk and tape devices necessity not live connected to the same router.

    Figure 6Figure 5.6 Server-Free Backup

    A backup server application on the Windows server discovers the data mover agent on the router, through Plug and Play. The backup application determines the details of the backup needs to live accomplished (disk device identifier, starting analytic block, amount of data to live backed up, and so on). The backup server software first issues a string of commands to the tape device to reserve the tape device and ensure that the reform media is mounted and properly positioned. When that is done, the backup server software issues an Extended Copy command to the data mover, resident in the router, which then coordinates the movement of the required data. When the operation has been accomplished, the data mover agent reports the status back to the backup software on the Windows server.

    Several different entities play a role in server-free backup architecture, including the data source, data destination, data mover agent, and backup server.

    The data source is the device containing the data that needs to live backed up. Typically a entire volume or disk partition needs to live backed up. The data source needs to live directly addressable by the data mover agent (described shortly). This means that storage devices connected directly to a server (or cases in which the server and the storage device maintain exclusive visibility) cannot live data sources for server-free backup because they cannot live addressed directly from outside the server.

    The data destination is typically a tape device where the data is to live written. The device may furthermore live a disk if one is backing up to disk instead of tape. Tape devices are typically connected to a fabric port to avoid disruption of the tape data traffic upon error conditions in other parts of the SAN. For example, if the tape were connected to an FC arbitrated loop, an error in another device or, for that matter, the event of a device joining or leaving the loop, would cause loop reinitialization, resulting in disruption to the tape data traffic.

    A data mover agent typically is implemented in the firmware of a storage router because the data mover agent must live able to act on the SCSI Extended Copy command, which is sent to the router in an FC packet. Switches and hubs that examine only the FC frame header are not readily suited to house data mover agents, though this may change in the future.

    The data mover agent is passive until it receives instructions from a backup server. Most tapes connected to SANs are SCSI devices, so a storage router (that converts between FC and SCSI) is typically required and provides a noble location for housing the data mover agent. Fibre Channel tapes are now appearing on the scene, and some vendors, such as Exabyte, are including data mover agent firmware in the FC tape device itself. In addition, native FC tape libraries are usually built with embedded FC-to-SCSI routers, installed in the library, providing the capacity for the library to maintain a data mover built in. Note that the data mover agent can furthermore live implemented as software in a low-end workstation or even a server. Crossroads, Pathlight (now ADIC), and Chaparral are some examples of vendors that maintain shipped storage routers with data mover agents embedded in the firmware. A SAN can maintain multiple data mover agents from different vendors, and they can total coexist.

    Of course, to live usable, a data mover agent needs to live locatable (via the SCSI Report LUNs command) and addressable (the WWN is used for addressing) from the backup server software. The data mover agent can furthermore create two simultaneous backups—for example, one to a geographically remote mirror to provide a calamity recovery solution—but the two commands must live built by the server that issued the third-party copy command.

    The backup server is responsible for total command and control operations. At the risk of being repetitious, it is worthwhile noting total the duties of the backup server. The backup server software first ensures availability of the tape device, using preempt SCSI Reserve and Release commands as appropriate. The backup server software then ensures that the reform tape media is mounted and positioned. It is furthermore responsible for identifying the exact address of the data source and the data's location in analytic blocks, as well as the amount of data that needs to live backed up. Once the backup server has total this information, it sends an Extended Copy command to the data mover agent. The data mover agent then issues a string of Read commands to the data source device and writes the data to the data destination.

    Computer Associates, CommVault, LEGATO, and VERITAS are some examples of vendors that ship a server-free backup software solution. Storage router vendors that ship server-free functionality routinely work with backup independent software vendors (ISVs) to coordinate back because many of the implementations consume vendor-unique commands to supplement the basic SCSI Extended Copy commands.

    Note that although server-free backup has been around for a while, there is very petite back for server-free restore.

    5.3.3.5 The Windows Server Family and Server-Free Backup

    A lot of the trade press and vendor marketing literature claims that a particular server-free backup solution is Windows 2000 compatible. It is worthwhile examining this title in more detail to understand what it means. The following discussion examines each of the four components that constitute the elements of a server-free backup solution: data source, data destination, backup software server, and data mover agent.

    In most cases a data mover agent outside a Windows NT server will not live able to directly address data sources internal to the Windows NT server. The HBAs attached to servers usually work only as initiators, so they will not respond to the Report LUNs command. If the Windows NT server is using a storage device outside the server—say, a RAID array connected to an FC switch—it will live visible to the data mover agent. So rather than saying that storage used by a Windows NT server cannot constitute the data source for a server-free backup, one needs to situation that storage internal to a Windows NT server cannot constitute the data source.

    Having the data destination internal to the Windows server is furthermore not possible, because the data destination furthermore needs to live directly addressable from outside the Windows box (by the data mover agent).

    Having the backup software dash on the Windows server is certainly feasible. The HBA attached to the Windows server can issue a string of Report LUNs commands to each initial LUN (LUN 0) that it discovers. The backup software then enumerates the list of visible devices and LUNs, and checks which ones are capable of being third-party copy agents. The backup software would maintain to deal with some minor idiosyncrasies; for example, some products report extra LUNs that necessity to live used when Extended Copy commands are being issued. Many backup applications that consume these devices travel through an additional discovery process to verify the data mover's functionality.

    The Windows NT SCSI pass-through (IOCTL) interface is capable of conveying the Extended Copy command to the data mover agent (from the Windows NT backup server). Windows NT does not maintain native back for data movers; Plug and Play can determine them, but drivers are required to log the data mover into the registry.

    That leaves the last case—that is, whether a Windows NT server or workstation can live used to dash the data mover agent software. One handicap is that such an agent would live able to address and access the storage devices visible to the Windows server. The backup server, however, which might live outside the Windows NT box, would not live able to note these storage devices inside the Windows NT server. The data mover agent needs to live capable of acting as an initiator and target for SCSI commands. Because the HBA connected to the Windows NT server rarely acts as a target, the Extended Copy command may not obtain through to the data mover agent.

    Note that in Windows NT, an application uses the SCSI pass-through interface (DeviceIoControl with an IoControlCode of IOCTL_SCSI_PASS_THROUGH or IOCTL_SCSI_PASS_THROUGH_DIRECT) to issue SCSI commands.
