Physically, a cluster is a grouping of two independent servers that can
access the same shared data storage and provide services to a common
set of clients. With current technology, this usually means servers
connected to common I/O buses and a common network for client
access.
Logically, a cluster is a single management unit. Any server can provide
any available service to any authorized client. The servers must have
access to the same shared data and must share a common security
model. Again, with current technology, this generally means that the
servers in a cluster will have the same architecture and run the same
version of the same operating system.
