You can add additional servers to your vSphere Bitfusion cluster when you require more GPU resources. To add a new server in a vSphere Bitfusion cluster, first you deploy the vSphere Bitfusion appliance on a virtual machine (VM), enable passthrough of the GPU to the vSphere Bitfusion server VM, customize the vSphere Bitfusion OVF template, and enable the VM as vSphere Bitfusion server.

After the first vSphere Bitfusion server starts, vSphere Bitfusion registers a vSphere Client Plug-in in the vCenter Server, resulting in a single vSphere Bitfusion cluster containing one vSphere Bitfusion server. To add a new server to your cluster, you must perform the steps that are listed as prerequisite, and enable the server in vCenter Server before you power on the VM. Additional vSphere Bitfusion servers must be part of the same vCenter Server instance as the first vSphere Bitfusion server.

Prerequisites

  • Verify that all existing vSphere Bitfusion servers are in a healthy state.
  • Verify that you deployed the vSphere Bitfusion appliance.
  • Verify that you customized the vSphere Bitfusion OVF template.
  • Verify that you enabled passthrough of the GPUs to the vSphere Bitfusion server VM.
  • Power off the vSphere Bitfusion server VM.

Procedure

  1. From the Hosts and Clusters view in vCenter Server, right-click the server VM.
  2. Select Bitfusion > Enable Bitfusion.
  3. In the Bitfusion Enablement dialog box, select the For a server, this will allow it to be used as a GPU server option, and click Enable.
  4. Power on the server VM.
    When you add multiple vSphere Bitfusion servers to a cluster, you must power on the VMs in a sequential order.
    Note: Do not power on the VM before enabling the VM in vCenter Server. Otherwise the new vSphere Bitfusion server replaces the vSphere Client Plug-in, which eliminates the cluster, and creates a new cluster.

Results

When a new vSphere Bitfusion server joins the cluster, vCenter Server supplies a token, a certificate, and a configuration to access the vSphere Bitfusion cluster.
