Cluster Configuration Options

You can create a cluster of two or more servers running Parallels Server Bare Metal to provide a

high degree of availability for your servers. A typical failover cluster implementation must meet the

following requirements:

• The cluster configuration is as follows:

• A shared SCSI storage device (iSCSI or Fibre Channel) is used as a cluster storage.

• The /vz partition is located on the shared SCSI storage device and formatted as ext3.

• Clustered file systems (GFS v1, GFS v2, and NFS) are not used.

• One and the same version of the Parallels Server Bare Metal software is installed on all servers

in the cluster.

• Only one /vz partition is created per clustered service.

• The following cluster resources are available in the cluster: the /vz filesystem, the

/etc/init.d/vz-cluster script, and the IP address resource.
