I think that you want to read how consistent hashing works, in brief,
it's not a simple modulo arithmetic mapping.
http://www.paperplanes.de/2011/12/9/the-magic-of-consistent-hashing.html
libmemcached has an option:
memcached_server_instance_st memcached_server_by_key(const memcached_st *ptr,
const char *key,
size_t key_length,
memcached_return_t *error)
Your language probably has a similar method server for key or by key.
