Novell Cluster Services supports up to 32 nodes in a single cluster. NetWare 6.5 customers receive a Novell Cluster Services entitlement that covers an unlimited number of two-node clusters. Customers who want to add nodes to any cluster can purchase a paper license for them for an additional fee. For information, see the Novell Cluster Services for Open Enterprise Server How-to-Buy Web site
Previous versions of Cluster Services required a Cluster User Access License (CUAL). NetWare 6.5 now uses User Access Licensing, which eliminates the need for a CUAL.
