Adding a Media Pool

Before adding a media pool, review the following prerequisites:

  • It is desirable for media pools to correspond to logical groups, such as business components (SALES_POOL, MARKET_POOL, etc.) or physical locations (EAST_POOL, WEST_POOL, etc.).

  • It is advantageous to locate a pool of media volumes near the backup devices where the volumes are mounted. This avoids the delay that can result when an operator must search elsewhere for the media volume requested by Catalogic DPX.

  • If the media pool is used for multiple device clusters, the device clusters and the media pool must be near each other. As you cannot predict the media volumes in the pool for which Catalogic DPX prompts, all free volumes in a pool must be easily available to all device clusters that might need it.

To add a media pool in DPX, do the following:

  1. Go to Devices & Pools in the sidebar. Switch to the Media Pools tab, then select the Add Media Pool button in the upper right corner. If you have added a device cluster through the web interface and kept the Automatically create corresponding media pool toggle on, some media pools (with the mp- prefix may already be on the list. They will be of Disk Directory type. Otherwise, the list is empty. See Adding a Device Cluster.

The Add Media Pool dialog will open.

  1. Specify the Media Pool Name. The name may only include alphanumeric characters (a-z, A-Z, 0-9), underscores (_) and hyphens (-). No other special characters are allowed. The name cannot be longer than 48 characters. The field is case-insensitive.

  2. Select Media Pool Type. Currently, only two types are available in the web interface:

    • Disk Directory

    • Cloud

    For other types, head to the desktop interface.

    If you select Cloud, an additional AWS S3 Storage Class drop-down will appear. There are three classes to choose from:

    • STANDARD

    • GLACIER

    • DEEP_ARCHIVE

    These are just types of AWS S3 subscription plans. You can learn more from the provider’s website.

  3. Optionally, you can add a brief description (max. 48 characters).

  4. Click Save. The Media Pool is now added.

Note. For Disk Directory, media pools are automatically created with 100 volumes.
