Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Provisioning and encryption ease improve data storage efficiency

To improve HPE Alletra Storage, it needs to have a true active-active controller; it claims to have an active-active controller from the back end, however, the second node is pretty much sitting there doing nothing. The MV 10000 series, which is the next series, is an improvement to HPE Alletra, and HPE is already doing that. In the next release, I would prefer to see better dedupe features; I know other companies do excellent dedupe, and they have protection group policies, meaning you have immutable data in case of a ransomware attack. If you're on the SAN, it should give you a way to protect that data without being erased. Other vendors have that capability built-in, ensuring that you can't erase the data, so features similar to that would be great.
