Overview
The Structure of a Cluster
A cluster includes the following physical components.
Servers. Each server must be running HP Clustered File System.
Public LANs. A cluster can include up to four network interfaces per
server. Each network interface can be configured to support multiple
virtual hosts, which provide failover protection for Web, e-mail, file
transfer, and other TCP/IP-based applications.
Administrative Network. HP Clustered File System components
communicate with each other over a common LAN. The network used
for this traffic is called the administrative network. When you configure
the cluster, you can specify the networks that you prefer to use for the
administrative network traffic.
