Answers
B.
Decrease the queue depth and execution throttle to 'minimum'
C.
Set the queue depth and execution throttle to '512'
Answers
C.
Set the queue depth and execution throttle to '512'
D.
Set the queue depth and execution throttle to '256'
Answers
D.
Set the queue depth and execution throttle to '256'
Suggested answer: D

Explanation:

For the integration of Oracle with XtremIO, the best practice for HBA drivers includes setting the LUN-queue depth to optimize performance. If a single host is connected to the X-Brick, the LUN-queue depth can be set to the maximum supported by the HBA, which is 256 for QLogic HBAs1. As additional hosts are added, this setting should be reduced proportionately until reaching a minimum of 32 to maintain optimal performance1.

Assess Host Connection: Determine the number of hosts connected to the X-Brick.

Set Queue Depth: For a single host, set the queue depth to 256. Adjust as necessary when more hosts are added.

Configure HBA Settings: Apply the queue depth setting in the HBA configuration.

Test Performance: Monitor the system's performance to ensure the settings are optimal.

Adjust if Necessary: If performance issues are observed, adjust the queue depth settings as needed.
