Symantec 5 manual Required disk space, Hardware requirements for a VCS cluster, Description

24Planning to install VCS Hardware requirements

Table 2-1	Hardware requirements for a VCS cluster
Item	Description
VCS nodes	From 1 to 32 Linux PPC systems running the supported Linux PPC
	operating system version.
DVD drive	One drive in a system that can communicate to all the nodes in the
	cluster.
Disks	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.
Disk space	Note: VCS may require more temporary disk space during installation
	than the specified disk space.
Network Interface	In addition to the built-in public NIC, VCS requires at least one more
Cards (NICs)	NIC per system. Symantec recommends two additional NICs.
	You can also configure aggregated interfaces.
Fibre Channel or	Typical VCS configuration requires at least one SCSI or Fibre Channel
SCSI host bus	Host Bus Adapter per system for shared data disks.
adapters
RAM	Each VCS node requires at least 256 megabytes.

Required disk space

Confirm that your system has enough free disk space to install VCS.
