Fusion-IO model impractical in the enterprise
Unless it has a way to perform real time mirroring to another server's flash you risk losing access to your data when a server goes down. With the data on an array another server can quickly pick up the task being performed by the downed server.
The Fusion-IO model means when a server goes down, you need to send an knowledgeable tech into the datacenter to quickly triage the problem and determine if the best course is to get the downed server up and running again, or yank the flash card out of the dead server and put it into another one. So much for the movement towards the lights out datacenter! We left behind the worries about stranded storage when we adopted SANs, and the worries about downed hardware were left behind with clustering and now virtualization. Apparently they want to turn back the clock.
