Overview for a two-node file server cluster
Servers in a failover cluster can function in a variety of roles, including the roles of file server, print
server, mail server, or database server, and they can provide high availability for a variety of other
services and applications. This guide describes how to configure a two-node file server cluster.
A failover cluster usually includes a storage unit that is physically connected to all the servers in
the cluster, although any given volume in the storage is only accessed by one server at a time.
The following diagram shows a two-node failover cluster connected to a storage unit.

Storage volumes or logical unit numbers (LUNs) exposed to the nodes in a cluster must not be
exposed to other servers, including servers in another cluster. The following diagram illustrates
this.
