By far one of the best breakout sessions of the week for me: technical and I can apply it in the field on pretty much a daily basis!

If you’ve got SSD drives in a VNX you can use it in two ways: as FAST Cache or as an extreme performance tier in your storage pools (FAST VP). Either of these implementations has advantages and disadvantages and they can also be used concurrently (i.e. use FAST Cache AND FAST VP). It depends on what you want to do…

But let’s start at the beginning: first you need to figure out your skew! What?!
