VCS nodes
|
From 1 to 32 systems running a supported AIX operating system.
Note: |
VCS is capable of supporting clusters with up to 64 nodes. Symantec has tested and qualified VCS configurations of up to 32 nodes at the time of the release. For more updates on this support, see the Late-Breaking News TechNote.

|
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).
Note: |
VCS also supports non-SCSI3 server-based fencing configuration in virtual environments that do not support SCSI-3 PR-compliant storage. |
See About planning to configure I/O fencing.

|
Disk space
|
Note: |
VCS may require more temporary disk space during installation than the specified disk space. |
|
|
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.
You can also configure aggregated interfaces.
Symantec recommends that you turn off the spanning tree on the LLT switches, and set port-fast on.

|
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 node requires at least 1024 megabytes.
