What are two appropriate criteria for evaluating a batch job performance? (Choose two.)

You are evaluating storage system performance for an interactive workload. What are three appropriate criteria in this situation? (Choose three.)

A 10K RPM Small Form Factor 600 GB disk drive has a 3 ms average rotational latency and a 4 ms average seek time. How many random read IOPS would you expect from a 4D+4D RAID group using these drives before any consideration for cache hits or queuing optimization benefits?

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

How many back-end disk operations are normally required to complete a small block random write operation to a LUN on a RAID 5 group?

In a VSP G200 system, what are two advantages of RAID 1+0 compared to RAID 5/6 for random write workloads? (Choose two.)

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

Which two statements are true about the Active Flash feature on the VSP Midrange? (Choose two.)

Which two port options are bi-directional on a VSP G800? (Choose two.)

On a VSP G1000, the maximum I/O Request Limit for an external initiator port has been exceeded. What are two consequences of this activity? (Choose two.)

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?

You are sizing a VSP G4000 for a customer who requires good performance but has a very limited budget. You now must select a cache size between 64 GB and 128 GB.
Which three conditions will affect your selection in this situation? (Choose three.)

A customer using a small block interactive workload on a VSP G200 complains about poor application performance. They use an FC SAN which consists of 8 Gbps and 16 Gbps FC switches.
What are two causes of the performance issue? (Choose two.)

You are designing a VSP G1000 solution for a customer and you need to determine the appropriate disk type and RAID level. What information do you need to design the solution? (Choose three.)

A customer is considering buying a new VSP Midrange system with iSCSI front-ends. The system will be used to support existing Oracle databases and a new MS Exchange mail system. The existing customer’s LAN has enough resources to handle the iSCSI traffic. They have provided the required storage for Oracle and MS Exchange.
What I/O profile information is required to size the VSP system in this scenario? (Choose two.)

Which two statements are true regarding HDP pools? (Choose two.)

A VSP G800 HDT pool contains FMDs, NL-SAS drives, external storage with 15K 600 GB SAS drives, and external storage with 10K 900 GB SAS drives.
Which tier level contains the NL-SAS drives in this configuration?

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?

Your customer has an HDP pool dedicated to interactive production workloads. Which two applications are good candidates to share this HDP pool? (Choose two.)

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 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.)

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?
