A compute manager, for example, vCenter Server, is an application that manages resources such as hosts and VMs. NSX-T Data Center polls compute managers to find out about changes such as the addition or removal of hosts or VMs and updates its inventory accordingly. It is optional to add a compute manger, because NSX-T gets inventory information even without a compute manger, such as standalone hosts and VMs.

In this release, this feature supports:

  • vCenter Server versions 6.5 Update 1, 6.5 Update 2, and 6.7.

  • IPv6 as well as IPv4 communication with vCenter Server.

  • A maximum of 5 compute managers.


    NSX-T Data Center does not support the same vCenter Server to be registered with more than one NSX Manager.


  1. From a browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Select Fabric > Compute Managers from the navigation panel.
  3. Click Add.
  4. Complete the compute manager details.



    Name and Description

    Type the name to identify the vCenter Server.

    You can optionally describe any special details such as, the number of clusters in the vCenter Server.

    Domain Name/IP Address

    Type the IP address of the vCenter Server.


    Keep the default option.

    Username and Password

    Type the vCenter Server login credentials.


    Type the vCenter Server SHA-256 thumbprint algorithm value.

    If you left the thumbprint value blank, you are prompted to accept the server provided thumbprint.

    After you accept the thumbprint, it takes a few seconds for NSX-T Data Center to discover and register the vCenter Server resources.

  5. If the progress icon changes from In progress to Not registered, perform the following steps to resolve the error.
    1. Select the error message and click Resolve. One possible error message is the following:
      Extension already registered at CM <vCenter Server name> with id <extension ID>
    2. Enter the vCenter Server credentials and click Resolve.

      If an existing registration exists, it will be replaced.


The Compute Managers panel shows a list of compute managers. You can click the manager's name to see or edit details about the manager, or to manage tags that apply to the manager.
