We are just having a new Compellent installed with SC9000s and then 6 x FS8600s for the NAS front end (our main usage will be NFS & SMB).
We have two storage tiers, SSD and SATA. When creating a NAS Pool for our FluidFS cluster it seems we can only create one pool whereas ideally we'd like to have one for SSD and one for SATA.
Do we split our FluidFS cluster into two (4 x FS86000 for SSD and 2 x FS8600 for SATA for example) so we can have two NAS pools or should we just allocate almost all the space over the two tiers into a single NAS pool and then the data will tier automatically on the SC9000?
The second option obviously is a single NAS Pool covering both tiers and then have faith in the auto-tiering but we really don't want most SMB shares using SSDs and don't want any critical applications (even if not heavily used all the time) being on SATA.
How do we set this up or are these the only two options?
