I just proposed this to IT at work since they proposed a $100k storage upgrade. I just want to make sure I have enough RAM. Currently thinking of OpenIndiana + napp-it but I cannot remember how to figure out how much RAM you need for a L2ARC so you don't starve your ARC. It will be setup in a ZFS pool of 2 9 disk Z3 arrays shared out via NFS to ESXi (unless 9 Mirrors would be faster?).
