what's peoples thoughts on SAN / LUN sizing and VM placement nowadays? If you were to setup a school from scratch, using what you have learnt from the last few years, what would you do differently:
How you would you setup your SAN?
How would you size your LUNs?
How would you decide where to place your VM's?
Would you dedicate for SQL or Exchange data and log files?
Basically i'm reviewing our SAN setup, and i've read a lot recently but i'm very interested in your opinions especially given you run school-style workloads.
