  2. storage response time
  3. customer requirements
  4. host initiators utilization

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.)

  1. variation of thread count
  2. variation of sequential and random access
  3. variation of RAID level
  4. variation of HBA queue depth
  5. variation of read and write

Answer(s): C,D,E



A user reports fluctuating LUN response times every day between 8:00 AM and 9:00 AM as users arrive and log in. How do you identify this condition using Hitachi Tuning Manager?

  1. View LUN response times and RAID group utilization (% busy) averaged over the 60 minutes.
  2. View the random write counts every minute.
  3. View LUN response times and RAID group utilization (% busy) every minute.
  4. View LUN response times and correlate against the Cache Write Pending level every 15 minutes.

Answer(s): A



A mission critical SQL server application that resides in a three-tier HDT pool is showing response time spikes that may be related to I/O activity.

Which three Hitachi Tuning Manager reports would you use to determine the problem? (Choose three.)

  1. IOPS by dataset.
  2. IOPS by V-Vol
  3. IOPS by pool
  4. IOPS by tier
  5. IOPS by parity group

Answer(s): C,D,E



A customer wants to add a new flash-based tier to an existing HDT pool. You refer to the Tier properties chart to determine if the workload in a disk-based HDT pool is a good candidate for adding a new and higher flash tier.

In this scenario, what does the chart tell you?

  1. The utilization line starts at a low level and gradually climbs to a high spike at the extreme right-hand side.
  2. The utilization line starts at a medium level on the left side and fails away slowly.
  3. The utilization line stays at a high level until half way across the chart then drops sharply.
  4. The utilization line starts at a high level on the left side then drops away sharply.

Answer(s): A
