VCS systems
|
From 1 to 32 SPARC systems running Solaris 8 or later.
|
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 applications that migrate between systems in the cluster. The VCS I/O fencing feature requires that all disks used as data disks or as coordinator disks must support SCSI-3 Persistent Reservations (PR).
The coordinator disk does not store data, so configure the disk as the smallest possible LUN on a disk array to avoid wasting space.
See Setting up I/O fencing.

Disk space
|
To run VCS, LLT, GAB, the Web Console, and the Java Console, each VCS system requires the following file system space:
-
550 MB in the /opt directory
(additionally the language pack requires another 15 MB)
-
300 MB in /usr
-
20 MB in /var
If you do not have enough free space in /var, then use the installvcs command with tmppath option. Make sure that the specified tmppath file system has the required free space.
-
10 MB in /
|
Ethernet controllers
|
In addition to the built-in public Ethernet controller, VCS requires at least one more Ethernet interface per system. Symantec recommends two additional interfaces.
|
Fibre Channel or SCSI host bus adapters
|
Typical VCS configuration requires at least one SCSI or Fibre Channel Host Bus Adapter per system for shared data disks.
|
RAM
|
Each VCS system requires at least 256 megabytes.
