• Question 225:

  Which of the following are correct regarding a Storage Array RAID 2.0 Typical Application Performance Tuning? (multiple choice)

  A. Scenario: Sequencing large IO services, especially 1M IO scenarios, with the phenomenon that the back-end read bandwidth is much larger than the front-end read bandwidth Tuning: Turn off the corresponding LUN prefetch policy
  B. scene: the order of pressure reading and writing business conditions, high utilization of hard drives Tuning means: increase the unplug-thresh device hard disk device
  C. Scenario: Oracle database in the operation of data backup, the data on the LUN bandwidth does not meet the requirements and accompanied by high utilization of hard disk Tuning means: the formal creation of POOL to increase the depth of the points
