5 Configure network interfaces When you add a server to the cluster, HP Scalable NAS determines whether each network interface on that server meets the following conditions: • The network interface is up and running. • Broadcast and multicast are enabled on the network interface. • Each network interface card (NIC) is on a separate network. Network interfaces meeting these conditions are automatically configured into the cluster. HP Scalable NAS ignores aliased network interfaces and does not configure them into the cluster. Overview Be sure that your network configuration meets the requirements specified in the HP Scalable NAS File Serving Software installation guide. Administrative traffic HP Scalable NAS uses a local network for its administrative traffic. It does not require exclusive use of this network; other site traffic can also use it. By default, HP Scalable NAS administrative traffic is allowed on all network interfaces. However, when you configure the cluster, you can specify the networks that you prefer to use for the administrative traffic. For performance reasons, HP recommends that these networks be isolated from the networks used by external clients to access the cluster. When HP Scalable NAS is started, the PanPulse daemon selects the administrative network from the available networks. When a new server joins the cluster, the PanPulse daemon on that server tries to use the established administrative network. If it cannot use that network, the PanPulse daemon on the new server will look for another network that all of the servers can use. If this attempt fails, the new server HP Scalable NAS File Serving Software administration guide 79
