Thank you for this post, Andy!
My knowledge has been enhanced.
Just a question though...
"A cluster is group of independent computers, also known as nodes, that are
linked together to provide highly available resources for a network. Each node that is a member of the cluster has both its own individual disk storage and access to a common disk subsystem, Systems that comprise the cluster operate as a team. When one node in the cluster fails, the remaining node or nodes assume responsibility for the resources that the failed node was running. This allows the users to continue to access those resources while the failed node is out of operation"
Does the cluster need a separate main server for the data base or does each node contain its own a data base or just the resources?
