You are partitioning a VSP G1000 with eight VSDs and 1024 GB cache, and are creating an 80 GB CLPR. In this scenario, how much cache does each VSD blade initially reference in the CLPR?

A customer plans to migrate an interactive application from a VSP to VSP G1000. The application has consistent access across all its capacity with low hit rates and no particularly high I/O access areas. The application latency must be less or equal to 1.5 ms. Which configuration do you recommend to satisfy the requirements?

A customer has several Oracle databases with different workload profiles residing on old HUS systems. The customer wants to consolidate workloads on a new VSP G800 system to increase database performance and to reduce costs. Which configuration would you use to accomplish this task?

Your VSP G1000 customer has an HDP pool with 600 GB drives and they need more IOPS in the pool. Which action will satisfy the requirement?

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.)

Immediately after migrating to a new HDT pool, Hitachi Tuning Manager shows that Tier 1 SSD, Tier 2 SAS, and Tier 3 NL-SAS are not busy for performance but Tier 1 and Tier 2 are over utilized for capacity. From this analysis, which action should be performed?

Relocation cycles are regulatory failing to complete in an HDT implementation where the customer is also reporting lower than expected performance. What should be done in this scenario?

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?

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 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?
