Chapter 7 Cluster Installation and Configuration 75
Network Requirements
The network requirements for clustering are:
• A unique NetBIOS cluster name
• Five unique, static IP addresses:
• two are for the network adapters on the internal network
• two are for the network adapters on the external network
• one is for the cluster itself
• A domain user account for Cluster Service (all nodes must be part of the same
domain.)
• Two network adapters for each node—one for connection to the external network and
the other for the node-to-node internal cluster network. If you do not use two network
adapters for each node, your configuration is unsupported. HCL certification requires
a separate private network adapter.
Shared Disk Requirements
Disks can be shared by the nodes. The requirements for sharing disks are as follows:
• Physically attach all shared disks, including the quorum disk, to the shared bus.
• Make sure that all disks attached to the shared bus are seen from all nodes. You can
check this at the setup level in <Ctrl> <M> (the BIOS configuration utility.) See page
69 for installation information.
• Assign unique SCSI identification numbers to the SCSI devices and terminate the
devices properly. Refer to the storage enclosure manual about installing and
terminating SCSI devices.
• Configure all shared disks as basic (not dynamic.)
• Format all partitions on the disks as NTFS.
It is best to use fault-tolerant RAID configurations for all disks. This includes RAID
levels 1, 5, 10, 30 or 50.
