That might not be a problem. Fusion-io's directCache is a write-though 
cache, so all writes are to disk, anyway. I think several other products 
behave the same to protect data integrity.

I'm looking for something that can cache a parallel filesystem from the 
client side. From what I've read of CacheCade, it only works with local 
disks directly attached to the PERC controller.
