communications link to be used and quantity
number of user terminals installed at the remote site
number of mainframe servers installed at the primary site
A customer is planning to replicate 66TB of data using Universal Replicator (UR).
What are two primary considerations for sizing the expected solution? (Choose two).
number of journal groups at both sides
communications link to be used and quantity
number of servers installed at the remote site
number of disk frames of the secondary subsystem
A customer is planning to replicate 66TB of data using Universal Replicator.What are
three primary considerations for sizing the expected solution? (Choose three.)
type of spare drives
total number of the I/O's for the environment
the percentage of writes for the environment
number of disk drives of the primary subsystem
number of RAID groups for journal disks at both sides
A customer is using ShadowImage to create point-in-time copies for backup to tape. This application has a high write workload, and you are concerned that the volumes cannot fully resync within the time allocated for the customer to suspend the point in time copies.Which two techniques are used to reduce the time necessary to achieve synchronization prior to suspend? (Choose two.)
Distribute volumes across parity groups.
Aggregate volumes onto a single parity group.
If the resync percentage exceeds 30%, delete and recreate the ShadowImage pairs instead.
Keep the pairs synchronized throughout the day, and only suspend them during the backup window.
A customer is using Copy-on-Write to create point-in-time copies for backup to tape.Which two are good strategies to minimize performance impact on the storage system? (Choose two.)
Increase pool capacity.
Suspend pairs as often as possible.
Keep pairs in pair status as much as possible.
Reduce the number of Copy-on-Write copies of a given volume.
Which two situations allow a DR site array to be smaller than the production site array?
The customer would like to reduce the administration requirement at the recovery site.
The customer is using storage-based rapid-recovery technology at their production
The customer has a significant portion of data that will not be replicating to the
The customer will move their tape robot to the DR site and keep extra point-in-time
copies at the DR site.
The customer is implementing Oracle on tiered storage. 9900Vs are attached to
USP100s as External Storage at the primary and secondary site. The expected application response time is 6ms. Which statement is true?
The log files must be allocated on the 9900V.
The cache size of the USP100 must be 4GB or less.
All database LDEVs must be located on the USP100.
The index files of the database must be allocated on the 9900V.
The customer is implementing a DR site point-in-time copy cascaded off of Universal
Replicator (UR). Which recommendation applies?
The point-in-time copy volumes should be dedicated to distinct parity groups.
The point-in-time copy volumes should share parity groups with the journal volumes.
There are no recommendations or restrictions on point-in-time parity group locations.
The point-in-time copy volumes should share parity groups with the UR target volumes.
A customer has two TagmaStore USPs and is considering Universal Replicator as a DR solution. You sized the configuration for them and told them how much cache they would need for this implementation.Which two statements are true about the cache sizing? (Choose two.)
The amount of cache at the secondary will differ based on options chosen.
Cache must be increased by 1.5 times at both the primary and the secondary.
No additional cache is required with Universal Replicator due to use of journals.
A cache increase of 1.25 times is recommended at the primary and at the secondary.
Which two statements are correct? (Choose two.)
TrueCopy generally requires more cache than XRC.
Cache sizing is not an issue with Universal Replicator due to journaling function.
In TrueCopy a sidefile puncture can occur if we run out of cache for replication.
Journal overflow does not generally occur in Universal Replicator if properly configured.
A customer is using Universal Replicator and wants to reduce resynchronization time. Which two strategies should be recommended to achieve this objective? (Choose two.)
Increase copy pace
Decrease copy pace
Increase the number of RAID Groups used for journals
Decrease the number of RAID Groups used for journals
What describes the technique for estimating resync time for a Copy-on-Write pair?
proportional to current write I/O rate
proportional to total volume capacity
proportional to current pool utilization for that pair
If the customer wishes to avoid host delay as sidefile utilization increases, how should
the USP be configured?
set Inflow Control to Enable, Offload Timer to 1
set Inflow Control to Disable, Offload Timer to 1
set Inflow Control to Enable, Offload Timer to the default
set Inflow Control to Disable, Offload Timer to the default
Which important sizing factor will impact whether Inflow Control will be encountered?
Increase the MCU cache by 50%.
Increase the MCU cache by 25%.
Size the RCU to have identical cache to the MCU.
Size the network bandwidth to the peak expected workload.
Hitachi facts programs certified skilled software new structure announcement
The Hitachi statistics methods certified knowledgeable program validates that our customers, partners and personnel have tested the skills, expertise and expertise to innovate with Hitachi information options.
it's a job-based program that offers lots of checks within the areas of storage solutions architecture, implementation and administration, the usage of Hitachi facts methods hardware, application, solutions, capabilities and expertise.
On can also 1, 2014, the HDS Academy is launching a new certification application constitution together with a number of other adjustments as the 1st step of a transition to a new certification framework.

the brand new Hitachi records programs licensed professional program aspects a 2-tier assessment structure during which low-stakes and excessive-stakes testing is used in combination with 4 credential degrees. This gives IT professionals the most appropriate evaluation method for his or her role and offers them with an upgrade path to accompany career growth, permitting candidates to validate their evolving knowledge through tests of improved complexity.
1. Accreditation-degree testingThis stage of testing leverages low-stakes tests typically used in 2 contexts:
standard Hitachi data systems accreditation exams include 25 to 35 varied-option questions, can also or may also not be proctored and might be delivered as closed-book or open-publication, both as end-of-path exams or in a stand-on my own format.
Passing an accreditation check results in a Qualification credential. Two levels are available:
2. Certification-degree testingCertification-degree checks are designed to easily and accurately validate that candidates have the potential, skills and potential to operate tasks specifically recognized as regarding their job in real-existence cases. in an effort to circulate certification exams, candidates are anticipated to use knowledge acquired through numerous means and experiences including a considerable number of formal and informal working towards and learning methods.
Hitachi information techniques certification tests typically include 55 to 60 dissimilar-option questions. they're closed-booklet proctored tests delivered at Prometric look at various centers.
Passing a certification exam results in a Certification credential. Two degrees are available:
