문제1

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?

A. Hitachi Tiered Storage Manager

B. Tier Properties Performance Graph

C. Hitachi Universal Volume Manager

D. Hitachi Server Priority Manager

정답: B

문제2

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

A. Using the largest possible pools is a recommended practice.

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

C. Tier migration is based on performance and space capacity.

D. HDP pools can be used for sizing HDT pools.

정답: A,D

문제3

A VSP G800 HDT pool contains FMDs, NL-SAS drives, external storage with 15K 600 GB SAS drives, and external storage with 10K 900 GB SAS drives.
Which tier level contains the NL-SAS drives in this configuration?

A. 4

B. 1

C. 3

D. 2

정답: B

문제4

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.)

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

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

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

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

정답: A,B

문제5

You are deploying an external storage system and its connection to a VSP G1000. The VSP G1000 has four external pools. You must ensure balanced utilization of the external storage system parity groups within each pool.
What would you do to satisfy this requirement?

A. Ensure that volumes from a parity group in an external system are exclusively associated with the same external parity group in the storage system connected to the host.

B. Slice each external parity group to provide a pool volume for each pool.

C. Use only one external volume per external parity group with the default UVM queue depth.

D. Provide eight paths for each volume presented by the external storage system to the storage system connected to the host.

정답: A

문제6

How does the HDLM Extended Round Robin algorithm impact sequential I/O?

A. It buffers and reorders I/O requests to improve sequence detection by the storage.

B. It continues to use the same path for a user-specified count of sequential I/O requests.

C. It remembers a user-determined number of addresses to better implement sequence detection for the storage.

D. It makes a path decision for every I/O request.

정답: B
