EMC CLARiiON CX4 series Review

It worked fine and was very reliable, though the throughput tended to be a bit slow


What is our primary use case?

Our first storage in our first steps towards virtualisation. It worked fine and was very reliable, though the throughput tended to be a bit slow. We used it for another four years after the service agreement ended.

How has it helped my organization?

We went from 24 hardware servers to four hardware ESX hosts. All 24 servers were turned into virtual machines. This was done within our time schedule and they performed well.

What is most valuable?

It was easy to manage.

What needs improvement?

  • It needs better deduplication. Deduplication was costing too many resources, hence we never used it. 
  • It needs more throughput, especially when after three years we had about 75 virtual machines running against the storage and it was time to update.

For how long have I used the solution?

More than five years.

What do I think about the stability of the solution?

It is very reliable. We never had an outage. 

How is customer service and technical support?

Whenever a disk had a problem, EMC was right on top of it. In some instances, they called me before I even knew what was going on. Service from EMC was extremely good.
