[Beowulf] SSD caching for parallel filesystems

[Prentice Bisbal]

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.

httP//www.dell.com/downloads/global/products/pedge/en/perc-h700-cachecade.pdf

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?
