VMWare Checks#

Check VMWare Disk Space#

Purpose#

To ensure the datastore(s) the cluster is using will be sufficient for the cluster.

Procedure#

  1. Log into the VMWare server(s) hosting the cluster nodes.

  2. Identify the Datastore each node is using.

  3. Ensure there is sufficient space for all systems.

Step to resolve#

If there is any doubt that datastore space may not be sufficient, contact your VMWare administrator.

VMWare Snapshots#

Purpose#

VMWare snapshot management is vital to ensure optimal performance.

Procedure#

  1. Log in on one VMWare host(s)

  2. Ensure that there is no more than one snapshot, if possible. Delete any old snapshots.

VMWare recommendations#

Purpose#

VOSS recommends that there be a 1 to 1 mapping for memory and CPU in VMWare.

Procedure#

  1. Log into the VMWare console, select the VOSS nodes one by one.

  2. Ensure that the system has a 1 to 1 mapping for memory and CPU. For example, if the system is set to 16GB, there is 16GB RAM reserved, and if CPU is set to 4 cores, that the VMWare host has 4 cores available.
