Hello,
We recently received a new Equallogic SAN, and I am trying to decide how to implement. Our first unit (currently only member in a pool) is a PS4100 with 24x600GB 10K SAS. The new unit is a PS4210 with 12x4TB 7.2K NL SAS.
Should I leave the units in separate pools in the same group, and carve out new LUNS? Should I add the PS4210 into the existing pool, and utilize storage tiering?
I'm a bit unsure about how the storage tiering will work, I've read quite a bit that when mixing disk types, storage tiering will balance on capacity, and most of the IO load will hit the higher capacity SAN.
Any input is appreciated. The storage is used for VMFS datastores with vSphere 5.5 cluster. Running EQL firmware 8.1.0 on both units.
