VNX virtual provisioning and storage tiering
If I have Unisphere Suite and Basic VNX Software (it is a VNX5400 array), does it make sense to configure pools consisting of performance and capacity drives, if I only have the Virtual Provisioning enabler installed? Will I be able to take advantage of storage tiering without FAST VP enabler?
Any input is appreciated.

I've always used Fast VP, so I'm not 100% sure, but I think you'll only be able to create homogeneous pools.(single drive type per pool)

Without FAST VP, you could not enable the auto-tiering feature which can automatically move the "hot data" to performance (SSD) tier..

I do not have SSDs, only SAS and NLSAS. Trying to figure out if it will make sense to put them in the same pool if I do not have FAST VP, only VNX Base software and Unisphere suite, which includes virtual provisioning. Not sure if in this case VP will do tiering between SAS and NLSAS. If not, whats the benefit of putting them in the same pool?

IF you are planning to use thin LUNs or deduplication it does make sense to have some SSD’s in the pool even without FAST because the meta data needed for both will then be allocated on SSD for faster access

Thanks Rainer, yes, I am planning to use thin LUNs, but I will have no storage-tiering without FAST VP anyway, will I? Adding SSDs is not an option. I am trying to figure out what will be the benefits to configure pools consisting of SAS and NLSAS drives, or it is going to make more sense to go with traditional RGs.

I'm still a little confused on what exactly you are asking so I'm going to give a couple responses:
Did one or both of those responses help?
