Cluster Fabric Management

Cluster Fabric is a service that helps manage servers (GPU Nodes) included in a GPU Cluster. Using Cluster Fabric, you can move servers between GPU Clusters in the same Node pool and optimize the performance and speed of GPUs within the same GPU Cluster.

Creating Cluster Fabric

Cluster Fabric can be created together with a GPU Node, and it cannot be created or deleted separately. When all GPU Nodes within a Cluster Fabric are terminated, the Cluster Fabric is automatically deleted. If you haven’t created a GPU Node, please create one first. For more information, refer to Creating a GPU Node.

Checking Cluster Fabric Details

You can check the created Cluster Fabric list and details, and move servers on the Cluster Fabric List page and Cluster Fabric Details page.

1. Click on All Services > Compute > Multi-node GPU Server menu. It will move to the Service Home page of the Multi-node GPU Cluster.

2. Click on the Cluster Fabric menu on the Service Home page. It will move to the Cluster Fabric List page.

   • On the Cluster Fabric List page, you can view the list of resources of the GPU Cluster created by the user.
   • Resource items other than required columns can be added through the Settings button.

     Category	Required	Description
     Resource ID	Optional	Cluster Fabric ID created by the user
     Cluster Fabric Name	Required	Cluster Fabric name created by the user
     Node Pool	Optional	A collection of nodes that can be bundled into the same Cluster Fabric
     Number of Servers	Optional	Number of GPU Nodes
     Server Type	Optional	Server type of the GPU Node The user can check the number of cores, memory capacity, and GPU type and number of the created resource
     Status	Optional	Status of the Cluster Fabric created by the user
     Creation Time	Optional	Time when the Cluster Fabric was created

Details

On the Details tab of the Cluster Fabric List page, you can check the details of the selected resource and bring in servers from other clusters.

Bringing in Cluster Fabric Servers

Using the Add Target Server feature on the Cluster Fabric Details page, you can bring in servers from other clusters and add them to the selected cluster.

1. Click on All Services > Compute > Multi-node GPU Server menu. It will move to the Service Home page of the Multi-node GPU Cluster.
2. Click on the Cluster Fabric menu on the Service Home page. It will move to the Cluster Fabric List page.
3. Click on the resource to check the details on the Cluster Fabric List page. It will move to the Cluster Fabric Details page.
4. Click the Add button on the right side of the target server on the details tab.
   • The target server addition popup window opens.
     • Cluster Fabric Select a cluster.
     • The GPU Node bound to the selected cluster is retrieved, and you can select the GPU Node to bring in.
     • The selected GPU Node is listed at the bottom with the GPU Node name.
     • Click the Confirm button to complete.
     • Click the Cancel button to cancel the task.
   • Check if the added GPU Node is retrieved in the target server.

Terminating Cluster Fabric

When all GPU Nodes within a Cluster Fabric are terminated, the Cluster Fabric is automatically deleted. For more information, refer to Terminating a GPU Node.
