4.7 Network Planning for the Cluster
Network planning for a cluster should be very similar to network planning for an individual server except that you have a lot more names – hosts and cluster – and IP addresses to deal with. In this section, we will discuss some issues around network planning for a cluster that may help in the overall implementation of the cluster.
4.7.1 Network Information for the Cluster
Before starting the installation of Tru64 UNIX, plan ahead and have all your network information ready and available. Network information should include the following:
-
Host names for each cluster member
-
Host IP addresses for each cluster member
-
Cluster name
-
Cluster IP address
-
Network Mask
-
DNS network domain
-
Primary and Secondary DNS server name
-
Primary and Secondary DNS server IP address
-
Primary and Secondary NTP server name
-
NIS domain
-
Primary NIS server name
-
Enable remote directory mounting or directory exporting using NFS
4.7.2 To gated or not to gated?
While gated is not required for a stand-alone Tru64 UNIX server, prior to version 5.1A Patch Kit 1, it is required to implement TruCluster Server. If you are implementing a version of TruCluster Server prior to version 5.1A Patch Kit 1, we recommend that when routing configuration is performed on the Tru64 UNIX server, as part of the configuration setup, that you choose to use gated in preparation for the implementation of TruCluster Server. For more information, please review Chapter 20 on Network Administration Tasks.
