On the ProLiant Cluster for NetWare 4.2, both nodes in the cluster monitor the other through three different interconnections. The cluster interconnects for the ProLiant Cluster for NetWare 4.2 are: • The Fibre Channel Arbitrated Loop and shared storage - the "Disk Link". • The servers' public LAN connection - the "NetWare Link". • An optional dedicated connection between the two servers - the "Dedicated Link". For an even higher level of availability, each interconnect can be configured with a redundant backup interconnect. The backup links consists of redundant Network Interface Cards (NICs) and cables for the NetWare and Dedicated links, and redundant Fibre Channel Host Controllers, storage hubs, Fibre Channel Array Controllers, and cables for the Disk link. If the primary interconnect fails, communication continues over the backup. The ProLiant Cluster for NetWare 4.2 consists of ProLiant Servers, the Compaq StorageWorks RAID Array 4000 storage system, Novell High Availability Server, Novell NetWare 4.2, and at least two network adapters. The optional dedicated link between the servers requires two additional network adapters. 0095-0699-A
