4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

Overview
The structure of a cluster
The following example shows a cluster including a FibreChannel switch.
The matrix includes these components:
Servers. Each server must be running Matrix Server.
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. Matrix Server 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. For performance reasons, HP
recommends that these networks be isolated from the networks used by external
clients to access the cluster.
