Hello Learned Peers!
Our primary SAN is optimized, as most are, for 70/30 read/write. I know I've got a few workloads that look more like 10/90. There are other that are closer to 30/70 and 50/50... So, I'm trying to identify the various SAN workload ratios for my VMs.. Then I can size a proper write optimized storage solution for those specific VMs.
Bearing in mind that there are between 10-20 VM's per volume, looking at the SAN or the actual datastore wouldn't help much. -- I guess I could create a new volume, and move the VM's to it one at a time and see what those stats look like... but that sounds like a big pain.
I'm not asking how to setup tiering, I don't have anything to tier with yet! 
Details: 5 hosts cluster/ ESXi 5.5 / vCSA 5.5 / Equallogic PS6500ES SAN over 1GB iSCSI
Thoughts?
