What is most valuable?
The consolidated storage: no need to use central storage that has a performance penalty. For example, while using central storage that enables file-sharing NAS services & SAN services, when one VM had an IO overload, all the VMs in the same data store in the VMware environment on the same LUN suffered from I/O latency. Now, in the new consolidated storage, this does not happen.
How has it helped my organization?
We can deploy VM as a service & we can perform updates on the nodes without downtime in a very simple, direct way.
What needs improvement?
The improvement needed is for elastic clusters, meaning the ability to depart and join nodes in an automatic way. We have a laboratory that needs to perform bare metal tests and therefore needs to unjoin the nodes from the cluster and later on join them back.
For how long have I used the solution?
I have used it for two years.
What do I think about the stability of the solution?
I have not encountered any stability issues.
What do I think about the scalability of the solution?
I have not encountered any scalability issues, but we are about to add another node to the cluster and it should be a very simple task .
How are customer service and technical support?
Technical support is very good, and good with responsive time.
Which solution did I use previously and why did I switch?
We were using central storage and suffered from bad performance latency.
How was the initial setup?
Initial setup was straightforward.
Which other solutions did I evaluate?
At the time we checked, this solution was unique.
What other advice do I have?
Perform resizing. Check the needs and deploy only what is needed. Check the memory DIMMs and make sure for the price you get, you have free DIMMs.
We Added a dedicated switch for this cluster so that all layer 2 networking will be in this switch and separate from the main routers.
