Dell EMC XtremIO Flash Review

The most valuable features are low latency, high I/O, and large bandwidth. When you lose one of the scale-out nodes, your hosts will see a large drop in I/O.


What is most valuable?

  • Low latency
  • High I/O
  • Large bandwidth
  • Helps my SAN perform at a high rate

How has it helped my organization?

It has improved the end-user experience:

  • More fluid VDI
  • Faster SQL searches
  • Quicker data migrations

What needs improvement?

Replication: XtremIO has none

Controller failover: When you lose one of the scale-out nodes on XtremIO, your hosts will see a large drop in I/O while it occurs and EMC is unaware of how their controllers work. As it is shown in their demos, the work load after a failure is spread across each node. But if you look at the “ACTUAL” process, the work is loaded on each node until that node gets to 100%. Then, the work goes to the next node and repeats. So, in the event of a failure, you will have several nodes at 100% and others at 25% load.

Data recovery: In the event of a dual power supply failure, the array has to be recovered from a backup.
