Your vSphere environment must meet certain software and hardware requirements for vSphere Advantage.

ESXi Host Requirements

ESXi host 6.5 or later.

vCenter Server Requirements

Ensure that the vCenter Server meets the following requirements:

  • vCenter Server Appliance version must be 7.0 Update 3a and later.
  • Configure the vCenter Server with a backup and restore mechanism.
  • Dedicate at least three ESXi hosts for the vCenter Server. (Recommended)
  • The vCenter Server must be self-managed. It must manage its own ESXi hosts and virtual machines.

    For your vCenter Server deployment, take the appropriate action to convert it to a self-managed vCenter Server.

    Table 1. Converting a vCenter Server to a Self-Managed vCenter Server
    vCenter Server Deployment Action
    vCenter Server deployed on an unmanaged host. Add the host to the management cluster. See Add a Managed Host to a Cluster.
    vCenter Server deployed on a standalone host managed by a different vCenter Server. Remove the host from the managing vCenter Server and add the host to the management cluster. See:
    vCenter Server deployed on a cluster managed by a different vCenter Server. Perform either of the following tasks:

Unsupported vCenter Server Configurations

vSphere Advantage does not support certain vCenter Server configurations:

  • Ensure that the vCenter Server is not configured in High Availability mode.
  • If the vCenter Server is configured in Enhanced Linked Mode (ELM), unlink it from ELM. See Repoint a vCenter Server Node to a New Domain. ELM is no longer required because with vSphere Advantage you can monitor your entire vSphere inventory in a single pane of glass.
  • Ensure that the vCenter Server is not configured with NSX for vSphere, vRealize Operations Manager, Site Recovery Manager, vCloud Suite, or vSAN.

Management Cluster Requirements

The cluster where you have deployed the vCenter Servers you plan to convert to subscription is the management cluster. You must install vCenter Cloud Gateway in the same cluster. Ensure that the management cluster meets the following requirements:

  • The vCenter Server that you plan to convert to subscription must manage the cluster.
  • For high reliability, the management cluster must meet DRS cluster requirements. See DRS Cluster Requirements.
Note: vSphere Advantage uses the management cluster for future updates of vCenter Servers that you plan to convert to subscription. Do not move the vCenter Servers out of this cluster.

In addition to the above requirements, the management clusters on which you plan to install vCenter Cloud Gateway must also meet certain hardware requirements. The hardware requirements depend on the number of vCenter Servers you plan to convert to subscription.

The following hardware requirements are for a single instance of vCenter Cloud Gateway. The number of instances you must install depends on the number of vCenter Servers you want to convert to subscription. You can connect up to 4 vCenter Servers on each vCenter Cloud Gateway instance. Therefore, plan your hardware accordingly.
