4.1 Overview
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 (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. This generally means that the servers in a cluster have the same
architecture and run the same version of the operating system.
