Commvault configuration

  • The sections that follow provide configuration guidance and best practices for configuring the Commvault CommCell.

    Basic

    This section describes the basic best practice for configuring PowerScale as a NAS client and the CommCell policy configurations.

    Basic configuration steps

    For configuration details, see the NDMP: Configuring NDMP backups section in

    Appendix: Integrations: Configuration steps.

    Advanced

    This section describes the advanced performance considerations.

    NDMP backup performance

    For increased performance, when multiple PowerScale nodes are available to participate in the backup, determine if the directory structures can be split into multiple paths. In which case, define these paths under different Subclients under a single PowerScale NAS client. This NAS client should be configured to use the FQDN configured on the PowerScale IP address pool that contains these nodes. If needed, stagger the start time of the Subclients to allow the jobs to be evenly distributed across the available nodes, which helps ensure that DNS caching is not being used.

    If more tape media is available than Subclients, define multiple data readers on some or all the Subclients that need additional performance. Also ensure that the device streams on the store policy are set high enough to cover all the tape media that will be used simultaneously.

    This configuration will use multiple PowerScale nodes, with each node using the PowerScale Multi-Stream feature to simultaneously distribute the data to multiple tape media.
