So apparently inventing your own SSD caching system is all the rage? We already had flashcache from Facebook : https://github.com/facebook/flashcache/ https://github.com/facebook/flashcache/
And bcache : http://bcache.evilpiepirate.org/ http://bcache.evilpiepirate.org/
However this one isn't kernel-based, so it won't help your NFS server or your postgresql engine. On the other hand it's much easier to build.
- wmf 14y agoBlock devices and memcached are totally different; of course you're going to need different implementations for different APIs.

- nwmcsween 14y agoAll these level caching systems work mostly on different layers, bcache deals with the block layer, flashcache deals with device mapper et al and so does enhanceio.
