If you're using memcached, using consistent hashing is largely a matter of configuration on the client side (although it's worth understanding how it works and why you want it). Pretty much any memcached client that's built on libmemcached comes with it although most aren't using it by default; the overhead of calculating the ring is significant and needs to be thought about e.g where you store it - not something you want to do on every request.
