I have been presented with a conundrum. Migrating to vSphere5 and a new EMC storage platform, should I suggest leveraging:
- EMC FAST-VP across large high performance VMFS5 extents for as many machines as possible?
- Not using FAST-VP and leveraging Storage DRS and Storage Profiles instead?
- Is there a performance hit on ~60TB VMFS5 extents? The less LUNS to track the better.
It makes sense to me to either optimize storage tiering at either the SAN or VMWare level, but not both.
I know there are questions you will have for me, please, ask away. Much appreciated.
