small and efficent.
Two identical email servers can be setup to share a private NFS
partion off a raid array. Each server provides the exact same
services as the other machine. Each machine has its own IP. All
clients are told to connect a third IP for services. One of the
servers will start out with the shared IP. If this server ever
dies and goes offline, the second server, using vqalive, will
detect the failure and assign the IP to itself. As a hot swap
over. Clients can then continue to get services. And the IP
address is switched transparently.
