Faking an SSD drive in vSphere

Notes on tricking VMware into thinking a datastore is actually an SSD drive. Very useful if you’re in a lab environment and want to just test some of the features in vSphere 5 that center around flash storage (but don’t have the funds to dedicate to actually having it.)

However it’s also useful if you actually have flash storage in a production environment but for some reason vSphere isn’t recognizing that fact.
