Negative. My original post was not motivated by this. I was motivated by 
just a 'what-if' line of thinking.

I just skimmed this press release, but this sounds similar to LSI's 
CacheCade product which Dell is offering in it's PERC H700 card, 
Fuision-io's directCache, or LSI's Nytro products


My ideas was client-based caching of a parallel filesystem, which has a 
significant flaw. One of those flaws that everyone overlooks, but when 
someone finally brings up, seems amazingly obvious: cache coherency.
