A cache server in Linux is typically used in front of a cluster. When a server in a cluster drop out, the cache server will determine which server in the cluster to use.
Is it possible to use 2 cache servers in Linux (redundancy)
In Lotus Domino a cache server is called a ICM (internet cluster manager). It is a manager running on the Domino server. Well it is not a cache, but is is used in the same manner as a Linux cluster front.
Is it possible to use 2 ICMs in front of a Domino web server running in a Domino cluster.
It should not be possible, but the Domino Administrator manual suggest a solution. It seems pretty weered, and difficult to understand the thinking behind such a solution. Study the pictures below, and tell me how it is possible to have 2 ICMs?
