You can edit cluster properties to enable vSAN for an existing cluster.

Prerequisites

Verify that your environment meets all requirements. See Requirements for Enabling vSAN.

Note: vSAN HCI Mesh compute clusters have limited configuration options.

Procedure

  1. Navigate to an existing host cluster.
  2. Click the Configure tab.
  3. Under vSAN, select Services.
  4. Click Configure vSAN.
  5. Select the type of vSAN cluster to configure, and click Next.
    • Single site cluster. For more information, see vSAN Deployment Options.
    • Single site cluster with custom fault domains. For more information, see "Managing Fault Domains in vSAN Clusters" in Administering VMware vSAN.
    • Two node vSAN cluster. For more information, see vSAN Deployment Options.
    • Stretched cluster. For more information, see Introduction to Stretched Clusters.
    • vSAN HCI Mesh compute cluster. For more information, see "Sharing Remote Datastores with HCI Mesh" in Administering VMware vSAN.
  6. Configure the vSAN services to use, and click Next.
    • Configure vSAN performance service. For more information, see Monitoring vSAN Performance in vSAN Monitoring and Troubleshooting.
    • Enable File Service. For more information, see vSAN File Service in Administering VMware vSAN.
    • Configure vSAN Network options. For more information, see Designing the vSAN Network.
    • Configure vSAN historical health service.
    • Configure iSCSI target service. For more information, see Using the vSAN iSCSI Target Service in Administering VMware vSAN.
    • Configure Data Management options, including deduplication and compression, data-at-rest encryption, and data-in-transit encryption. For more information, see Administering VMware vSAN.
    • Configure capacity reservations and alerts. For more information, see About Reserved Capacity in vSAN Monitoring and Troubleshooting.
    • Configure advanced options:
      • Object Repair Timer
      • Site Read Locality for stretched clusters
      • Thin Swap provisioning
      • Large Cluster Support for up to 64 hosts
      • Automatic Rebalance
  7. Claim disks for the vSAN cluster, and click Next.
    Each host requires at least one flash device in the cache tier, and one or more devices in the capacity tier. For more information, see "Managing Disk Groups and Devices" in Administering VMware vSAN.
  8. Review the configuration, and click Finish.
