Detailed Description

Maintain the N:1 hash key to server relationship used for consistent hashing.

Consistent hashing for the servers ensures that even with changes to the server list, many of the data keys will continue to mapped to the same server. This ensures that changes to the server list doesn't invalidate the entire cache.
