Tutorial: Scale clusters in a private cloud

To get the most out of your Azure VMware Solution private cloud experience, scale the clusters and hosts to reflect what you need for planned workloads. You can scale the clusters and hosts in a private cloud as required for your application workload. You should address performance and availability limitations for specific services on a case-by-case basis.

In this tutorial, learn how to use the Azure portal to:

[!div class="checklist"]

  • Add a cluster to an existing private cloud
  • Add hosts to an existing cluster

Prerequisites

You need an existing private cloud to complete this tutorial. If you don't already have a private cloud created, follow the create a private cloud tutorial to create one.

If you are planning on using the AV64 SKU, define a network for the management and control plane. In your Azure VMware Solution private cloud, under Manage, select Clusters > Add a cluster. Then add the Address block for AV64 clusters (one /23 network or three /25 networks) under the Extended address block tab and select Save.

Add a new cluster

  1. In your Azure VMware Solution private cloud, under Manage, select Clusters > Add a cluster. Then select the required SKU from Size of host and specify the Number of hosts for the cluster. Prices listed in image are for illustration only.

We do not allow the mixing of AV36, AV36P, or AV52 SKUs within the same cluster. We only allow the addition of AV64 clusters to existing private clouds that are built with the AV36, AV36P, or AV52 SKUs in certain regions. For more information.

  1. The deployment of the new cluster will begin.

Delete an existing cluster

Caution

Deleting a cluster terminates all running workloads and components and is an irreversible operation. Once you delete a cluster, you cannot recover the data.

  1. In your Azure VMware Solution private cloud, under Manage, select Clusters.

  2. Select the Cluster you plan to delete, select More (...), select Delete.

  3. The deletion of the cluster will begin.

Scale a cluster - Host Addition

  1. In your Azure VMware Solution private cloud, under Manage, select Clusters.

  2. Select the cluster you want to scale, select More (...), then select Edit.

  3. Select Add Host to add a host to the cluster. Repeat that to reach the desired number of hosts, and then select Save.

    The addition of hosts to the cluster begins.

    [!NOTE] The hosts will be added to the cluster in parallel.

Scale a cluster - Host Removal

Note

Scaling down a cluster successfully requires all objects (VM/vmdk/iso/etc) on a vSAN datastore to be configured with a storage policy below or equal to RAID level requirements. Scaling down a cluster will place requested host(s) into maintenance mode prior to actual removal of host from vCenter inventory. Clusters cannot be scaled down past the minimum requirement of 3 hosts per cluster.

  1. In your Azure VMware Solution private cloud, under Manage, select Clusters.

  2. Select the cluster you want to scale down, select More (...), then select Edit.

    :::image type="content" source="media/tutorial-scale-private-cloud/ss4-select-scale-private-cloud-2.png" alt-text="Screenshot showing where to edit an existing cluster." lightbox="media/tutorial-scale-private-cloud/ss4-select-scale-private-cloud-2.png" border="true":::

  3. Select the host you want to remove, select More (...), select Delete, then select Save.

    :::image type="content" source="media/tutorial-scale-private-cloud/remove-host-from-cluster.png" alt-text="Screenshot showing how to remove a host from an existing cluster." lightbox="media/tutorial-scale-private-cloud/remove-host-from-cluster.png" border="true":::

    The removal of a host from the cluster begins.

Next steps

If you require another Azure VMware Solution private cloud, create another private cloud following the same networking prerequisites, cluster, and host limits.
