Cluster Fabric Management

Cluster Fabric is a service that helps manage the 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 GPU performance and speed within a single GPU cluster.

Create Cluster Fabric

Cluster Fabric can be created together when a GPU Node is created, and it cannot be created or deleted separately. If all GPU Nodes in the Cluster Fabric are terminated, the Cluster Fabric is automatically deleted.
If you have not created a GPU Node, please create a GPU Node first. For more details, please refer to GPU Node 생성하기.

Check detailed information of Cluster Fabric

On the Cluster Fabric List page and the Cluster Fabric Details page, you can view the generated Cluster Fabric list and details, and move the server.

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

2. On the Service Home page, click the Cluster Fabric menu. 2. Go to the Cluster Fabric List page.

   • Cluster Fabric List page allows you to view the resource list of the GPU Cluster you created.
   • Resource items other than the required columns can be added through the Settings button.

     Category	required status	Detailed description
     Resource ID	Selection	User-generated Cluster Fabric ID
     Cluster Fabric name	Required	User-created Cluster Fabric name
     Node pool	Selection	A collection of nodes that can be grouped into the same Cluster Fabric
     Number of servers	Selection	Number of GPU Nodes
     Server type	Selection	Server type of GPU Node The user can view the number of cores, memory capacity, and GPU type and count of the created resources
     status	Selection	Status of the user-created Cluster Fabric
     Creation date and time	Selection	Cluster Fabric creation timestamp

Detailed Information

On the Cluster Fabric List page’s Details Tab, you can view the detailed information of the selected resource and retrieve servers from another cluster.

Import Cluster Fabric server

Using the Add Target Server feature on the Cluster Fabric Details page, you can import servers from another cluster and add them to the selected cluster.

1. All Services > Compute > Multi-node GPU Server Click the menu. 1. Go to the Service Home page of the Multi-node GPU Cluster.
2. On the Service Home page, click the Cluster Fabric menu. 2. Go to the Cluster Fabric List page.
3. Cluster Fabric List page: click the resource to view detailed information. 3. Navigate to the Cluster Fabric Details page.
4. Click the right Add button on the target server in the Details tab.
   • The popup window for adding a target server opens. *
     • Select a cluster in Cluster Fabric.
     • GPU nodes associated with the selected cluster are listed; select the GPU node you want to retrieve.
     • The selected GPU Node’s name is displayed at the bottom.
     • Press the Confirm button to complete.
     • Pressing the Cancel button cancels the operation.
   • Check whether the added GPU Node is visible on the target server.

Terminate Cluster Fabric

If all GPU Nodes in the Cluster Fabric are terminated, the Cluster Fabric is automatically deleted. For more details, see GPU Node 해지하기.
