[Beowulf] SSD caching for parallel filesystems

You could use something like CacheFS for client side caching, but this will
always be a read only cache.

The newer versions of CacheCade can do write caching which could be pretty
useful for speeding up RAID6 on the servers. Pretty sure there are other
options to do write caching on the server (like Bcache).
