A customer with a VSP G1000 is using HDT with SAS 15K drives and external storage. The customer wants the daytime response-sensitive workload to benefit from tiering. They also want to minimize the impact of relocations on the daytime operation itself.
In this scenario, which action will satisfy the requirements?
Which three statements are true regarding the Hitachi external storage architecture? (Choose three.)
A VSP G1000 performance analysis shows that server response times for virtualized volumes are high, 100 ms and higher, but HDD utilization rates in an external HUS 150 never exceed 35%. There are no processor or path constraints in the configuration. The workload is steady and stable. Which two actions will optimize this configuration? (Choose two.)
A customer complains about high response times. This occurs frequently with bursts of write I/O at 6,000 IOPS for 10 second periods during each minute. The write response is 60 ms during these 10 second periods. The average IOPS rate reported by Hitachi Tuning Manager over 1 minute is 600.
In this scenario, what is the average response time over 1 minute?
A VSP G1000 customer is concerned about high VSD utilization alerts during their nightly backup and application maintenance window. To address their concerns, you want to inform them about the maximum acceptable utilization level range. What would be the range in this scenario?
