Scaling an ANS service

After deploying the Arcfra Network Service (ANS) service, you can scale the Arcfra network controllers, including increasing the number of Arcfra network controllers and upgrading resource configuration.

Viewing the Arcfra network controller information

1. Enter the Arcfra Operation Center (AOC) Network and security page, click Settings in the left sidebar, and select the ANS service for which you want to update.

2. Click Arcfra Network Controller in Operations to view the details.

Note:

If total and usage data for vCPU, memory, and storage cannot be displayed, there are two possible reasons:

• The cluster to which the Arcfra network controller virtual machines belong has not associated with an observability service.

  When the collected monitoring data size in the cluster is about to reach the reserved resource limit for basic monitoring, some metrics of the virtual machine will stop being collected. Refer to the Deployment > Deploying Observability > Deployment steps > Deploying an observability service section in the corresponding version of Observability to deploy the observability service.

• The Arcfra network controller virtual machine is abnormal.

  When the virtual machine is in the Updating, Suspend, Shutdown, or Unknown state, related metrics cannot be obtained. You need to restore the virtual machine to the normal state first.

Increasing the number of Arcfra network controllers

You can increase the number of Arcfra network controller virtual machines as needed to improve the availability of the ANS service.

Before enabling the distributed firewall or the VPC networking feature, the number of Arcfra network controller virtual machines needs to be increased to 3 or 5.

1. Enter the AOC Network and security page, click Settings in the left sidebar, and select the ANS service for which you want to update.

2. Click Arcfra Network Controller in Operations to enter the configuration page.

3. Click Scale out on the right side of Arcfra Network controller VMs.

4. Select the number of virtual machines, and configure the VM network and management IP address for each newly added Arcfra network controller. After completion, click Save.

Scaling up the Arcfra network controller configuration

If you need to use two or more features, you need to upgrade the Arcfra network controller configuration to at least Medium.

1. Enter the AOC Network and security page, click Settings in the left sidebar, and select the ANS service for which you want to update.

2. Click Arcfra Network Controller in Operations to enter the configuration page.

3. Click Scale up on the right side of Configuration.

4. Select the configuration and click Save.
