[Beowulf] SSD caching for parallel filesystems

Beowulfers,

I've been reading a lot about using SSD devices to act as caches for 
traditional spinning disks or filesystems over a network (SAN, iSCSI, 
SAS, etc.).  For example, Fusion-io had directCache, which works with 
any block-based storage device (local or remote) and Dell is selling 
LSI's CacheCade, which will act as a cache for local disks.

Are there any products like this that would work with parallel 
filesystems, like Lustre or GPFS? Has anyone done any research in this 
area? Would this even be worthwhile?
