VCS hardware requirements
Table: Hardware requirements for a VCS cluster lists the hardware requirements for a VCS cluster.
Table: Hardware requirements for a VCS cluster
One drive in a system that can communicate to all the nodes in the cluster.
Typical configurations require that the applications are configured to use shared disks/storage to enable migration of applications between systems in the cluster.
The SFHA I/O fencing feature requires that all data and coordinator disks support SCSI-3 Persistent Reservations (PR).
SFHA also supports non-SCSI3 server-based fencing configuration in virtual environments that do not support SCSI-3 PR-compliant storage.
In addition to the built-in public Ethernet controller, VCS requires at least one more Ethernet interface per system. Veritas recommends two additional interfaces.
You can also configure aggregated interfaces.
Veritas 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.
Each VCS node requires at least 256 megabytes.
