Hardware requirements for a VCS cluster
DescriptionItem
From 1 to 32 Linux PPC systems running the supported Linux PPC
operating system version.
VCS nodes
One drive in a system that can communicate to all the nodes in the
cluster.
DVD drive
Typical VCS configurations require that shared disks support the
applications that migrate between systems in the cluster.
The VCS I/O fencing feature requires that all data and coordinator
disks support SCSI-3 Persistent Reservations (PR).
See “About setting up disk-based I/O fencing” on page 89.
Disks
Note:VCS mayrequiremore temporarydiskspaceduring installation
than the specified disk space.

In addition to the built-in public NIC, VCS requires at least one more
NIC per system. Symantec recommends two additional NICs.
You can also configure aggregated interfaces.

Each VCS node requires at least 256 megabytes.RAM
Required disk space
Confirm that your system has enough free disk space to install VCS.
Table 2-2 shows the approximate disk space usage by directory for the Veritas
Cluster Server RPMs.
