Reliable and fast servers with good support
We use on-premise servers with Lenovo ThinkSystem. We set up Hyper-V and load multiple types of servers including a domain controller, a SQL Server, and application servers The solution provides fast servers that are reasonably priced. We set up RAID ten to ensure drive redundancy, leading to…
Jaehoon Oh - PeerSpot reviewer
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.
