<div><br>I should expand on that a little bit. 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.<br><br>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.<br>
<br>Somthing like this. <a href="http://www.amazon.com/OCZ-Technology-Drive-240GB-Express/dp/B0058RECUE">http://www.amazon.com/OCZ-Technology-Drive-240GB-Express/dp/B0058RECUE</a> or something from FusionIO if you want something that's aimed more at the enterprise.<br>
