  What I/O profile information is required to size the VSP system in this scenario? (Choose two.)

  A. transactions per second collected from the Oracle databases
  B. the planned amount of MS Exchange mailboxes and IOPS per user
  C. the planned amount of e-mails per second the MS Exchange system will send and receive
  D. IOPS and R/W ratio collected from the Oracle databases
  B. the planned amount of MS Exchange mailboxes and IOPS per user
  D. IOPS and R/W ratio collected from the Oracle databases

• Question 2:

  B. It calculates parity.
  C. It manages cache segment usage.
  D. It moves data to/from cache.
  E. It executes software such as HDP or copy products.
  A. It executes host I/O requests.
  C. It manages cache segment usage.
  D. It moves data to/from cache.

• Question 3:

  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.

• Question 4:

  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.)

  A. Increase the external path LUN queue depth setting.
  B. Increase the number of LUNs mapped from the external RAID group.
  C. Change Cache Mode to "Disabled".
  D. Increase the server HBA LUN queue depth to 64.
  A. Increase the external path LUN queue depth setting.
  C. Change Cache Mode to "Disabled".

• Question 5:

  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. type of workloads
  B. workloads read-write ratio
  C. operating systems used in the environment
  D. fan-in and fan-out ratios
  E. expected I/O rates
  A. type of workloads
  B. workloads read-write ratio
  E. expected I/O rates

• Question 6:

  A high level of writes to external storage is backing up into a VSP G1000 cache, creating a high write pending problem that is affecting other workloads. Which three actions will help to minimize this problem? (Choose three.)

  A. Add more cache to the enterprise storage system.
  B. Add more cache in the external storage.
  C. Quarantine the LUNs in a separate cache partition.
  D. Set Cache Mode to "Disabled" for the external LUNs.
  E. Address the throughput constraints in the external storage.
  A. Add more cache to the enterprise storage system.
  B. Add more cache in the external storage.
  D. Set Cache Mode to "Disabled" for the external LUNs.

• Question 7:

  Which three statements are true regarding a VSP G400 configuration for a Microsoft Exchange Server environment? (Choose three.)

  A. RAID 1+0 is a recommended RAID level for the database volumes.
  B. RAID 6 is a recommended RAID level for the database volumes.
  C. HDP is a recommended configuration for database volumes.
  D. Parity group concatenation is recommended.
  E. Microsoft JetStress testing should be used to validate the required performance.
  B. RAID 6 is a recommended RAID level for the database volumes.
  D. Parity group concatenation is recommended.
  E. Microsoft JetStress testing should be used to validate the required performance.

• Question 8:

  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?

  A. Re-asses after HDT performs page migration cycles.
  B. Add more drives to Tier 1.
  C. Add more drives to Tier 1 and Tier 2.
  D. Remove the SSD tier.
  C. Add more drives to Tier 1 and Tier 2.

• Question 9:

  A. When capacity is pooled; the whole pool is affected when one parity group fails.
  B. RAID 6 provides the most efficient use of system processor resources.
  C. RAID 6 minimizes exposure to double disk failure.
  D. RAID 6 provides the optimum overall performance of all RAID types.
  B. RAID 6 provides the most efficient use of system processor resources.
  C. RAID 6 minimizes exposure to double disk failure.
