I was told that if the service level policy was not defined i.e. Diamond, Platinum, etc... that the storage group would use service level called FC pool. If this is so what is FC pool? and what is the significance of a storage group using this pool verse the others?
If no SL is applied to a storage group, then Optimized is assumed. There is no SL called "FC Pool." From the manual:
"By default, all data in the VMAX3 storage array is managed by the Optimized SLO. However an explicit response time target may be set for an application by associating it with one of the other service level objectives."
