Unity 400 Hybrid Pool setup Suggestion ?!?

Question

Hello all,I'm new to Unity management. we had a old VNX 5300 configured with multiple LUNs and now with our Unity we can create pool and vmware profile. I plan to go with VVols blocks. Ok here is my question. We have an Hybrid setup. and we don't plan to expend storage capability for the next 1-2 years. I'm not sure what is the best to setup and I want to make the best decision at the beginning. So here is my setup:104 TB raw in performance tiers15 TB raw in extreme tiers flash sas and we have 4 400GB configured as fast cache (800GB). we are running mainly DEV stuff and about 20% of storage is PROD (internet services, DB and web services) I have 3 idea of setting up storage. 1) setup 2 pool. 1 pool is performance + fast cache and 1 pool is extreme + fast cache2) setup 3 pool, 1 pool is about 50% storage performance, 1 pools is 50% performance + fast cache and 1 pool is extreme + fast cache 3) mix all storage in 1 pool + fast cache and let the systeme decide what go in flash or SAS I would like to use Vmware profile to be able to switch from perf to extreme or from different tiers for specific needsand I want to be able to use the maximum storage capability of the SAN without loosing storage by a bad config. (like we have right now with LUNs) For information we currently (old SAN) have a storage capacity of 65TB and we are almost full, so the new Unity offer a little bite more and having VVols block will help us to no wast space. And a bonus question is 4+1 better then 8+1 raid 5 ? Any suggestion or comment will help me the do the right choice for our need. thanks you Martin

I'd suggest reviewing the Unity Best Practices Guide as a start - this provides the information on who to setup the Unity for Best Performance.
