AppFabric Named Caches structure

Is it possible to have an AppFabric Cache configuration wher开发者_如何学Pythone I have named caches that use some (but not all) of the servers in a cluster?

Specifically I want to have 3 different named caches: one will expand through server 1 and 2; the second through servers 3 and 4 and the other one through 1, 2, 3 and 4.

Server 1 and 2 are physically on location A, while servers 2 and 3 are on another location B.

Is this kind of configuration viable?

There's no way to do this - when you create a named cache you can't limit to a subset of the servers in your cluster. This is the correct design for maintaining redundancy: if you have a cache on servers 1 and 2, and server 1 goes down, you'd want your cache to move to, say, servers 2 and 4 so you maintain the caches' availability.

You can maintain the specific cache using regions as app fabric supports regions that are limited to machines. May be you can clone regions across servers while creating them.
