A

Question 2

You are sizing a storage system for a response-sensitive database application in a VMware environment. Which two statements are true in this scenario? (Choose two.)

Accepted Answer

The peak load requirements of the database and filesystem is a key factor in determining the resources required to meet response time requirements. Server virtualization will change the I/O profile of the application as viewed by the storage.

Question 3

Accepted Answer

NL-SAS drives are typically used in tier 1 of a VSP G800 HDT pool.

Question 4

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?

Accepted Answer

Adding more drives to Tier 1 and Tier 2 will increase the capacity of both tiers, reducing the over-utilization.

Question 8

A customer has an HDP pool with four array groups and 600 GB SAS drives operating at 85% utilization. Four array groups of the same configuration were added to the pool. In this scenario, which metric should be reviewed to validate optimal pool performance?

Accepted Answer

Reviewing the pool array group utilization will help determine if the addition of new array groups has balanced the load and improved performance, ensuring no single group is overutilized.

Question 9

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?

Accepted Answer

The answer of A customer has several Oracle databases with...

Question 10

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

Accepted Answer

Customer relationship management and software development are interactive workloads that can benefit from the high-performance capabilities of an HDP pool.

Question 11

A customer has a VSP G800 storage system with an HDT pool with internal SAS drives and a virtualized third-party array using SATA RAID 6. The virtualized array is connected to the VSP G800 using four 8 Gbps FC paths. The customer reports performance problems on an OLTP application deployed on a virtualized server using the HDT pool. What are two reasons for this problem? (Choose two.)

Accepted Answer

A) The workload includes significant random writes to SATA over RAID 6.D) The speed of the FC links is insufficient.

Question 12

When testing an external LUN with default mapping on two paths, performance appears constrained and the utilization of the RAID group in the external storage system never exceeds 35% busy no matter how many test threads are generated. You want to increase the utilization of the external RAID group. Which two actions will accomplish this task? (Choose two.)

Accepted Answer

The answer of When testing an external LUN with default...

Question 13

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.)

Accepted Answer

The answer of A VSP G800 customer has one HDT...

Question 14

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?

Accepted Answer

Ensure that volumes from a parity group in an external system are exclusively associated with the same external parity group in the storage system connected to the host.

Question 15

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?

Accepted Answer

The answer of Relocation cycles are regulatory failing to complete...

Question 16

What are two benefits of placing transaction log files on RAID 1+0 disks for Microsoft SQL Server databases rather than RAID 5 disks? (Choose two.)

Accepted Answer

The answer of What are two benefits of placing transaction...

Question 17

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?

Accepted Answer

The answer of A customer plans to migrate an interactive...

Question 18

You are planning for a performance upgrade for a transaction application. Which three metrics are necessary to determine the required back-end storage configuration in this scenario? (Choose three.)

Accepted Answer

Question 19

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

Accepted Answer

The answer of Which two statements are true regarding HDP...

Question 20

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?

Accepted Answer

Enabling monitoring only during the daytime and performing relocations at other times ensures that the response-sensitive workload benefits from tiering without impacting daytime operations.
