Astra Control Center supports NetApp ONTAP and Longhorn as storage backends.

Overview

Astra Control Center supports the following:

  • Storage classes backed by ONTAP storage: If you are using an ONTAP backend, Astra Control Center offers the ability to import the ONTAP backend to report monitoring information.

  • CSI-based storage classes backed by Longhorn: You can use Longhorn with the Longhorn Container Storage Interface (CSI) driver.

Note Storage classes should be configured using Astra Control Provisioner.

Storage classes

When you add a cluster to Astra Control Center, you're prompted to select one previously configured storage class on that cluster as the default storage class. This storage class will be used when no storage class is specified in a persistent volume claim (PVC). The default storage class can be changed at any time within Astra Control Center and any storage class can be used at any time by specifying the name of the storage class within the PVC or Helm chart. Ensure that you have only a single default storage class defined for your Kubernetes cluster.
