You can add compute clusters to your VMware Integrated OpenStack deployment to increase processing capacity.

Prerequisites

Note: If you want to add compute clusters from a separate vCenter Server instance, you must deploy VMware Integrated OpenStack with NSX-T Data Center networking. Other networking modes do not support adding compute clusters from separate vCenter Server instances.

If you have added resources to your vSphere environment after deploying OpenStack, refresh your vCenter Server instance before proceeding.

  1. Log in to the Integrated OpenStack Manager web interface as the admin user.
  2. In OpenStack Deployment, click the name of your deployment and open the Manage tab.
  3. On the Settings tab, click vCenter Credentials.
  4. In the VC Resources column for the desired vCenter Server instance, click Refresh.

Procedure

  1. Log in to the Integrated OpenStack Manager web interface as the admin user.
  2. In OpenStack Deployment, click the name of your deployment and open the Manage tab.
  3. On the Compute tab, click Add.
  4. Under Configure Nova computes, click Add.
  5. From the vCenter Server drop-down menu, select the vCenter Server instance containing the compute cluster that you want to add.
    ( NSX-T Data Center only) If the desired vCenter Server instance is not displayed, click the Add (plus sign) icon and enter its host name and credentials.
  6. Enter an availability zone for the new compute cluster.
    Compute clusters located in different vCenter Server instances cannot be in the same availability zone.
  7. From the Cluster name drop-down menu, select the desired compute cluster.
  8. Select one or more datastores for the compute cluster to consume and click Submit.

Results

The capacity of your deployment increases accordingly with the size of the additional compute cluster.

What to do next

You can add or remove datastores from a compute cluster by selecting the desired cluster and clicking Edit.

You can remove compute clusters from your deployment by selecting the desired cluster and clicking Delete. Ensure that all OpenStack instances in the cluster have been deleted before you remove the cluster.
