Hi, In general, Memcached was not built for HA.
IMO this is #1 drawback of Memcached, as these days many people are storing information on Memcached without backing it with persistence RDBMS/NoSQL solution; in-order to maintain the high-throughput low-latency of their application. That being said, there some open source and commercial solutions that solve this issue, e.g. Redis <http://redis.io>, Membase (now Couchbase)<http://www.couchbase.com/wiki/display/couchbase/Home>, and Garantia <http://www.garantiadata.com/>.
