Manage GPU (Specific VPC)

GPU enables an Instance to handle high-performance parallel compute tasks such as AI/ML model training, inference, and graphics rendering. You can select a GPU Instance type at creation time, or add a GPU to an existing standard Instance after it has been created.

GPU management is only available for Instances in Specific VPC.

Add a GPU to an Instance​

Requirements​

  • The Instance must belong to Specific VPC.
  • The Instance must be in Stopped (POWERED_OFF) state.
  • The Image must have GPU drivers installed — when selecting an image, prefer images labeled GPU to ensure driver compatibility.

Steps​

Step 1: Power off the Instance

If the Instance is running, perform a Power Off first. See Power Operations Guide.

Step 2: Open the Add GPU dialog

From the Instance list or detail page, click the action menu → select Add GPU.

Add GPU dialog

Step 3: Select the vGPU type

The system displays a list of vGPU types compatible with the Instance's current Flavor. Select the type that suits your workload.

Important: The vGPU list is filtered by the Instance's Flavor. If the current Flavor is not compatible with any vGPU type, you need to resize the Instance to a compatible Flavor first.

Step 4: Confirm

Click Confirm. After the operation completes, power the Instance back on using Power On.

Important: Adding a GPU requires the Instance to be in Stopped state. If the Instance is running when this operation is performed, the system will reject the request.

Remove a GPU from an Instance​

Step 1: Power off the Instance (if running).

Step 2: From the action menu → select Remove GPU.

Step 3: Confirm in the dialog. The system will remove the GPU and the Instance reverts to its original Flavor configuration.

Change the GPU Type (Edit GPU Plan)​

If the Instance already has a GPU and you want to switch to a different vGPU type:

Step 1: Power off the Instance (if running).

Step 2: From the action menu → select Edit GPU Plan.

Step 3: Select the new vGPU type from the list → click Confirm.
