C. customer requirements

D. host initiators utilization

Which two environments are suitable for cost effective use of Hitachi Accelerated Flash disk media? (Choose two.)

A. Online Analytical Processing (OLAP) data warehouse

B. Online Transaction Processing (OLTP) with HDT

C. large scale Consumer Video on Demand (CVOD)

D. Virtual Desktop (VDI)

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

A. It executes host I/O requests.

B. It calculates parity.

C. It manages cache segment usage.

D. It moves data to/from cache.

E. It executes software such as HDP or copy products.

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

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

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

A VSP G800 customer has one HDT pool with three tiers and they report a high frequency of relocations up and down between Tier 1 and Tier 2, affecting the HDT pool performance.

Which two actions will help solve the issue? (Choose two.)

A. Decrease the monitoring period of the HDT pool.

B. Increase the size of the grey zone between Tier 1 and Tier 2.

C. Change the HDT pool setting from Period mode to Continuous mode.

D. Increase the size of Tier 2.

A user with a diskless VSP G800 uses ShadowImage from the G800 with a virtualized VSP G200 system. Application performance suffers during the frequent ShadowImage resynchronization operations.

What should be done to reduce the impact of the ShadowImage throughput in this scenario?

A. Configure both sets of disks into an HDT pool and let the HDT scheme manage the different workloads.

B. Define the ShadowImage target volumes to use dedicated external FC paths using dedicated RAID groups.

C. Set Copy to 15.

D. Increase the VSP G800 cache size to improve the application cache hit rates.

Which two UNIX commands provide metrics about disk device I/O activity? (Choose two.)

A. perfmon

B. iogen

C. iostat

D. sar

You need to run a benchmark test to verify the performance of a new multi-user database storage implementation before loading the real data.

What are three features you will need in the benchmark/workload generator to accomplish this task? (Choose three.)

A. variation of thread count

B. variation of sequential and random access

C. variation of RAID level

D. variation of HBA queue depth

E. variation of read and write

For which two purposes is the SVP Performance Monitor suitable? (Choose two.)

A. Reporting by device owner

B. Annual trend analysis

C. Real time observations

D. A reference for verifying the accuracy of other performance tools

You are troubleshooting a potential marginal link in a SAN fabric that you believe is causing a performance problem.

To troubleshoot this problem, which two actions will allow you to view the detailed port statistics? (Choose two.)

A. Use the vendor's GUI.

B. Use the appropriate host command(s).

C. Use the appropriate switch command(s).

D. Use SVP Performance Monitor.
