Dell EMC Exam D-XTR-DY-A-24 Topic 2 Question 21 Discussion

Actual exam question for Dell EMC's D-XTR-DY-A-24 exam
Question #: 21
Topic #: 2
[All D-XTR-DY-A-24 Questions]

In a heterogeneous environment, what is a recommended setting when multiple storage arrays are connected to VMware vSphere in addition to XtremIO X2?

Show Suggested Answer Hide Answer
Suggested Answer: A

In the event of a power failure, the XtremIO X2 system's NVRAM (Non-Volatile Random Access Memory) card will initiate the discharging of the SuperCapacitor (SuperCap). The SuperCap is designed to provide enough power to the NVRAM card to allow it to write any data in transit to a non-volatile storage medium, ensuring data integrity and preventing loss1. This process is a critical part of the XtremIO X2's data protection mechanism during unexpected power interruptions.

Wait, XCOPY? Is this some kind of secret storage ninja technique I haven't heard of? I'm going to need to look that one up.

I'm going to go with option A. Increasing the number of outstanding disk requests could be a good way to optimize the system.

XCOPY sounds like an interesting option, but I'm not sure if it's the recommended setting for this particular scenario.

Option C looks promising. Adjusting the fnic_max_qdepth setting could help handle the increased workload from multiple storage arrays.

XCOPY = 256 could be another option to optimize the storage arrays' performance.

I think Disk.SchedNumReqOustanding = 32 might also be a good setting to consider.

I think option B sounds like the best choice. Increasing the disk scheduling quantum could help improve performance in a heterogeneous environment.

I disagree, I believe it should be C) fnic_max_qdepth = 128 because it helps with queue depth.
