New Features and Capabilities

Running multiple instances of VAST CSI Driver

You can run multiple VAST CSI Driver instances on the same Kubernetes cluster.

To do so, deploy each instance under its own name specified on the csiDriverName parameter in the driver instance's Helm chart configuration file. Each driver instance needs to be deployed in its own namespace. After deployment, you can supply the driver instance name when specifying the provisioner for a storage class (or a snapshot class), as well as when supplying the driver name in your pod definition.

For more information, see the VAST CSI Driver 2.5 Administrator's Guide.

Passing VAST QoS policy ID for a Storage Class

In addition to specifying a QoS policy name for a storage class, you can also pass the ID of the QoS policy using the new qos_policy_id parameter in the storage class definition provided in a Kubernetes YAML configuration file.

Note
Supplying qos_policy_id in the Helm chart configuration file (values.yaml) is not supported.
