[All Dell XtremIO Deploy Achievement Questions]

A systems administrator recently purchased XtremlO for their Oracle environment. Along with path failover software, which best practice for HBA drivers is reinforced in the

integration of Oracle with XtremIO?

AIncrease the queue depth and execution throttle to 'maximum'

BDecrease the queue depth and execution throttle to 'minimum'

CSet the queue depth and execution throttle to '512'

DSet the queue depth and execution throttle to '256'

Show Suggested Answer

Suggested Answer: D

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.

A, for sure! Gotta max out those settings to get the most out of XtremIO!

I'm not so sure about that. Decreasing the queue depth and throttle might be a better approach to avoid any potential issues with the integration. Better safe than sorry, right?

But setting it to '512' provides a balance between performance and stability, which is crucial for Oracle integration.

Nah, I reckon the answer is C. 512 is a nice, round number, and it's probably the sweet spot for balance between performance and stability.

I think C is the best option too. It seems like a good balance.

I disagree, I believe it is better to increase the queue depth and execution throttle to 'maximum'.

Hmm, I think setting the queue depth and execution throttle to the maximum would be the best practice for HBA drivers in this case. Gotta squeeze every bit of performance out of that XtremlO!
