Question 1

Which three functions are performed by a VSP G1000 Virtual Storage Director (VSD)? (Choose three.)

AIt executes host I/O requests.

BIt calculates parity.

CIt manages cache segment usage.

DIt moves data to/from cache.

EIt executes software such as HDP or copy products.

Answer : A, C, D

Question 2

DP-Vol LUNs are taken from an HDP pool deployed with 128 disks (16x4D+4D RAID groups). Access is random read.

Which combination of FC paths, LUN Queue Depth, and number of DP-Vols will result in a per-disk queue of 4 within this pool?

A2 paths, a LUN Queue Depth of 16, and 32 DP-Vols

B2 paths, a LUN Queue Depth of 8, and 32 DP-Vols

C4 paths, a LUN Queue Depth of 8, and 32 DP-Vols

D4 paths, a LUN Queue Depth of 16, and 32 DP-Vols

Answer : D

Question 3

Response times in an HDP pool have been increasing consistently with each additional workload during a large scale migration. The response times may become unacceptable with subsequent migrations. The

purchase of additional equipment is an acceptable solution. What are two valid actions in this scenario?

(Choose two.)

AIncrease the pool free space and alert thresholds to the maximum permitted levels.

BExpand the pool with volumes from new parity groups to reduce utilization levels.

CApply the SOM to provide tier property information that assesses suitability for HDT and deployment of flash.

DUse more, smaller, pool LDEVs per parity group to improve the efficiency and utilization of the queues.

Answer : A, C

Question 4

A high level of writes to external storage is backing up into a VSP G1000 cache, creating a high write pending problem that is affecting other workloads.

Which three actions will help to minimize this problem? (Choose three.)

AAdd more cache to the enterprise storage system.

BAdd more cache in the external storage.

CQuarantine the LUNs in a separate cache partition.

DSet Cache Mode to ''Disabled'' for the external LUNs.

EAddress the throughput constraints in the external storage.

Answer : A, B, D

Question 5

Which three statements are true regarding the Hitachi external storage architecture? (Choose three.)

AEnabling Cache Mode increases exposure to problems with high Cache Write Pending.

BEnabling Cache Mode allows destaging asynchronously from host I/O.

CEnabling Cache Mode always improves performance.

DA System Option mode can force in sequence destaging even when destaging asynchronously.

EDisabling Cache Mode for an external LDEV eliminates the use of cache.

Answer : A, B, D

Question 6

A customer is considering buying a new VSP Midrange system with iSCSI front-ends. The system will be used to support existing Oracle databases and a new MS Exchange mail system. The existing customer's LAN has enough resources to handle the iSCSI traffic. They have provided the required storage for Oracle and MS Exchange.

What I/O profile information is required to size the VSP system in this scenario? (Choose two.)

Atransactions per second collected from the Oracle databases

Bthe planned amount of MS Exchange mailboxes and IOPS per user

Cthe planned amount of e-mails per second the MS Exchange system will send and receive

DIOPS and R/W ratio collected from the Oracle databases

Answer : B, D

Question 7

Which three key metrics are required for sizing applications? (Choose three.)

Acache read hit ratios

BIOPS

CI/O read/write ratios

Dnumber of BED pairs

Eport speed

Answer : A, B, C
