Which disk format should be used for ESXi Disks provisioned by XtremIO?

AThin

BThick

CZeroed thick

DEager zeroed thick

Show Suggested Answer

Suggested Answer: D

For ESXi disks provisioned by XtremIO, the recommended disk format is 'Eager Zeroed Thick'. This format is preferred because it allocates all the space required for the disk at the time of creation and zeroes out any previous data on the physical media. Compared to other formats, 'Eager Zeroed Thick' provides better performance due to the pre-zeroing of the disk space, which helps in avoiding any latency that might occur during write operations as there is no need to zero out blocks before writing new data.

While the specific Dell XtremIO Design document was not available, the general best practice for high-performance storage solutions like XtremIO is to use 'Eager Zeroed Thick' provisioning for VMs running on VMware ESXi to ensure optimal performance1.

Additional information on disk provisioning and best practices can be found in VMware's official documentation and Dell EMC's storage configuration guides2.

Based on my understanding, Zeroed thick would be the best choice to ensure the full capacity of the XtremIO disks is utilized.

I think the answer is Thin, since XtremIO is a high-performance all-flash array and thin provisioning would be the most efficient option.

Hmm, I'm not sure about this one. I'll need to review the details on disk formats for ESXi and how they interact with XtremIO.

Hmm, I'm a bit confused by the different options. I'll need to double-check the DTD to make sure I understand the expected element order and content.

Alright, let's do this. The key is identifying how the GSC changes impact the VAF, and then recalculating the aAFPA. I'm feeling confident I can solve this.

Hmm, I'm torn between B. Thick and D. Eager zeroed thick. Maybe I should just go with the one that sounds the most enthusiastic about zeroing things out.
