You must have at least one access node for Kubernetes. For faster backups and restores, you can add more access nodes.
Network interface for backup data
Scale the Kubernetes access nodes horizontally for consistent scaling and performance.
For resilience scaling, add an additional access node. If the recovery point objective (RPO) cannot be met within the backup window, add additional access nodes.
Generally, approximately 32TB data can be transferred in a standard 8 hour backup window, on a 10GbE network configuration.
In addition, the read speed from disks, the network throughput from worker nodes, and the network throughput on your access nodes affect the amount of data transferred in the backup window.

Automatic Load Balancing Across Access Nodes
To manage your growing Kubernetes data, instead of increasing the hardware specifications of your access node, add more access nodes (with identical hardware specifications) to your Kubernetes hypervisor.
The Commvault software performs automatic load balancing across the access nodes.
Third-party maintenance (minor) releases or feature releases that are supported by the Commvault software may not be listed in our System Requirements. When possible, Commvault provides information on any known issues related to these minor releases or feature releases. In some cases, these minor releases or feature releases affect how the Commvault software works. Commvault software may experience changes in functionality as the result of the third-party minor release or feature releases. These changes are beyond the control of Commvault. Platforms that are supported in the current version of Commvault software may not be supported in earlier versions of the software. Contact your software provider to ensure that third-party minor releases or feature releases are compatible with the Commvault software.
Additional considerations regarding minimum requirements and End-of-Life policies from third-party vendors also apply.
