VMware Cluster Site Requirements

Ensure that your VMware cluster site meets the following requirements:

■

The configuration process assumes that you have a VMware cluster that contains at least two ESXi servers controlled by vCenter server.

■

The clustered VM servers should be connected to a shared network storage of type iSCSI or any other types supported by VMware ESXi.

For example, a datastore “QASWDatacenter” which contains a cluster named “qaswCluster01” and is combined of two ESXi servers ( figure below).

■

Verify that Shared Storage is defined and mounted for all cluster members:

Storage Adapters

■

Ensure that the 'Turn On vSphere HA' check box is selected:

Turn On vSphere HA

■

Ensure that HA is activated on each cluster node:

Activate HA on each Cluster Node

■

Ensure that the networking configuration is identical on each cluster node:

■

Ensure that the vMotion is enabled on each cluster node. The recommended method is to use a separate virtual switch for vMotion network (this should be defined in all cluster nodes and interconnected):

Switch Properties

■

A VM will be movable and HA protected only when its hard disk is located on a shared network storage on a cluster. You should choose an appropriate location for the VM hard disk when you deploy the OVOC VM. If your configuration is performed correctly, a VM should be marked as “protected” as is shown in the figure below:

Protected VM

If you wish to manually migrate the OVOC VMs to another cluster node, see Managing Clusters.
