Flashcache is a kernel module created by Facebook that uses the device mapper interface in Linux to provide a ssd cache layer to any block device. What I think would be interesting is using flashcache with a pcie ssd as the caching device. That would add about $500-$600 to the cost of each brick node but should be able to buffer the active IO from the spinning media pretty well. Somthing like this. http://www.amazon.com/OCZ-Technology-Drive-240GB-Express/dp/B0058RECUE or something from FusionIO if you want something that's aimed more at the enterprise. -- David -------------- next part -------------- An HTML attachment was scrubbed...
