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

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.
