That's quite interesting - tiered storage for Memcache - but I already hate them for not open-sourcing it. Facebook made some amazing performance changes to Memcache and had no qualms about open-sourcing it. I'm not that convinced about the whole tiered-storage thing. Memcache is a simple LRU cache. The moment it stops being a simple cache is the moment you've started doing it wrong. This is the golden rule which has been worked out over several years of Memcache development.
