Managing storage clusters in Astra Control as a storage backend enables you to get linkages between persistent volumes (PVs) and the storage backend as well as additional storage metrics. You can monitor storage capacity and health details, including performance if Astra Control Center is connected to Cloud Insights.

For instructions on how to manage storage backends using the Astra Control API, see the Astra Automation and API information.

You can complete the following tasks related to managing a storage backend:

View storage backend details

You can view storage backend information from the Dashboard or from the Backends option.

In the Storage Backend Details page, for Astra Data Store, you can see the following information:

  • Astra Data Store cluster

    • Throughput, IOPS, and latency

    • Used capacity compared to total capacity

  • For each Astra Data Store cluster volume

    • Used capacity compared to total capacity

    • Throughput

View storage backend details from the Dashboard

Steps

  1. From the left navigation, select Dashboard.

  2. Review the Storage backend section that shows the state:

    • Unhealthy: The storage is not in an optimal state. This could be due to a latency issue or an app is degraded due to a container issue, for example.

    • All healthy: The storage has been managed and is in an optimal state.

    • Discovered: The storage has been discovered, but not managed by Astra Control.

Add nodes to a storage backend cluster

You can add nodes to an Astra Data Store cluster, up to the number of nodes supported by the type of license installed for Astra Data Store.

What you'll need

  • A deployed and licensed Astra Data Store storage backend

  • You have added the Astra Data Store software package in Astra Control Center

  • One or more new nodes to add to the cluster

Steps

  1. From the left navigation, select Backends.

  2. Select the name of a storage backend.

  3. Under Basic Information, you can see the number of nodes in this storage backend cluster.

  4. Under Nodes, select the edit icon next to the number of nodes.

  5. In the Add nodes page, enter information about the new node or nodes:

    1. Assign a node label for each node.

    2. Do one of the following:

      • If you want Astra Data Store to always use the maximum available number of nodes according to your license, enable the Always use up to maximum number of nodes allowed check box.

      • If you don't want Astra Data Store to always use the maximum available number of nodes, select the desired number of total nodes to use.

    3. If you deployed Astra Data Store with Protection Domains enabled, assign the new node or nodes to Protection Domains.

  6. Select Next.

  7. Enter IP address and network information for each new node. Enter a single IP address for a single new node, or an IP address pool for multiple new nodes.
