interconnect, you can more easily alter or expand your cluster’s hardware configuration as newer and faster technologies become available.
1.2 Memory Requirements
Cluster members require a minimum of 128 MB of memory.
1.3 Minimum Disk Requirements
This section provides an overview of the minimum file system or disk requirements for a
1.3.1 Disks Needed for Installation
You need to allocate disks for the following uses:
•One or more disks to hold the Tru64 UNIX operating system. The disk(s) are either private disk(s) on the system that will become the first cluster member, or disk(s) on a shared bus that the system can access.
•One or more disks on a shared SCSI bus to hold the clusterwide root (/), /usr, and /var AdvFS file systems.
•One disk per member, normally on a shared SCSI bus, to hold member boot partitions.
•Optionally, one disk on a shared SCSI bus to act as the quorum disk. See Section 1.3.1.4, and for a more detailed discussion of the quorum disk, see the TruCluster Server Cluster Administration manual.
The following sections provide more information about these disks. Figure
1.3.1.1 Tru64 UNIX Operating System Disk
The Tru64 UNIX operating system is installed using AdvFS file systems on one or more disks on the system that will become the first cluster member. For example:
dsk0a root_domain#root
dsk0g usr_domain#usr
dsk0h var_domain#var
The operating system disk (Tru64 UNIX disk) cannot be used as a clusterwide disk, a member boot disk, or as the quorum disk.
