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?

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

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.an HDT pool consisting of SAS 10K and FMD drives
• B.an HDP pool consisting of external LDEVs provisioned on a VSP F400 system
• C.an HDP pool with FMD drives
• D.an HDP pool consisting of NL-SAS and FMD drives

A large bank is completing a capacity planning exercise and wants to upgrade their current VSP G1000 to properly support their online banking application for the next 18 months. The IT department wants to know where they should invest to achieve the transactional Service Level Objective (SLO).

• C.Measure throughput of all SAN directors.
• D.Measure the existing I/O profile.
• E.Export two months of Performance Monitor data.

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 Universal Volume Manager
• B.Hitachi Tiered Storage Manager
• C.Hitachi Server Priority Manager
• D.Tier Properties Performance Graph
