Question 1

An experienced system administrator reports near maximum MPB utilization with VSP G400 arrays operating in a GAD pair. Each array is supporting 100K IOPS with a 50% read workload. The MPBs should be capable of supporting more than 200K IOPS with this profile according to the basic array sizing tools.

Which two statements are correct in this scenario? (Choose two.)

ACache mirroring between the two G400 arrays generates an extra MPB load which is not recorded in Hitachi Tuning Manager.

BEach G400 array is also processing 50K duplex write IOPS from the other G400.

CThe duplex GAD writes are changing the overall read/write I/O profile and the extra parity operations are causing the high MPB utilization.

DThe internal array queue management scheme for GAD write operations causes MPB utilization to be doubled.

Answer : B, D

Question 2

You are sizing a VSP G4000 for a customer who requires good performance but has a very limited budget.

You now must select a cache size between 64 GB and 128 GB.

Which three conditions will affect your selection in this situation? (Choose three.)

AThe customer plans to use Cache Logical Partitions (CLPRs)

BThe customer environment is mainly VMware.

CThe number of LDEVs that are available.

DThe customer will use ShadowImage.

EThe number of connected hosts.

Answer : A, C, E

Question 3

A large bank is completing a capacity planning exercise and wants to upgrade their current VSP G1000 to

properly support their online banking application for the next 18 months. The IT department wants to know where they should invest to achieve the transactional Service Level Objective (SLO).

In this scenario, which three recommendations would you make? (Choose three.)

AMeasure throughput of all SAN directors.

BExport two months of Performance Monitor data.

CMeasure the storage resource utilizations.

DRequest a statement of growth requirements.

EMeasure the existing I/O profile.

Question 4

You are planning for a performance upgrade for a transaction application.

Which three metrics are necessary to determine the required back-end storage configuration in this scenario?

(Choose three.)

Acache read hit ratio

Bread/write ratio

Ctransfer rates

Dqueue depth

EIOPS

Answer : A, B, E

Question 5

For a VSP G1000 system serving a mission critical interactive workload, which two statements are true about VSD failover? (Choose two.)

AThe VSD receiving the workload of a failed VSD is not pre-determined.

BProviding reserved capacity to accommodate failure is a requirement when planning for capacity for normal operations.

CThe workload of a failed VSD board always transfers to its redundant partner VSD board.

DThe workload of a failed VSD board is dynamically redistributed among surviving VSD boards.

Answer : B, C

Question 6

Which two statements are true regarding HDP pools? (Choose two.)

AUsing the largest possible pools is a recommended practice.

BExposure to failure and recovery from failure must be considered when recommending the maximum size of a pool.

CHDP pools can be used for sizing HDT pools.

DTier migration is based on performance and space capacity.

Answer : A, C

Question 7

Your customer has a VSP G1000 with an HDT pool with two tiers (SAS 15K and SAS 10K). The response

times have increased over time to an unacceptable level. They want to add a flash tier and they ask you if this solution will be appropriate.

Which tool should you use to satisfy the requirement?

AHitachi Server Priority Manager

BHitachi Tiered Storage Manager

CHitachi Universal Volume Manager
