Adding Disks to the Storage Pool

Applies To: Data Protection Manager, System Center Data Protection Manager 2007

The storage pool is a set of disks on which the System Center Data Protection Manager (DPM) 2007 server stores replicas and recovery points for protected data. Before you can start protecting data, you must add at least one disk to the storage pool. After configuration, you can add more disks to the storage pool.


DPM does not support USB/1394 disks.

For more information and guidelines for choosing disk types and calculating capacity requirements for your storage pool, in "Planning a DPM 2007 Deployment", see Planning the Storage Pool (

To help you estimate your storage space needs, download the DPM storage calculator (

DPM 2007 requires a disk that is dedicated to the storage pool and a disk that is dedicated to the following:

  • System files

  • DPM installation files

  • DPM prerequisite software

  • DPM database files


Adding a disk to the storage pool is not a requirement if you are going to use custom volumes to protect your data sources, or if you are only going to use disk-to-tape protection.

You can install DPM on the same volume that the operating system is installed on or on a different volume that does not include the operating system. However, a disk on which you install DPM cannot be added to the storage pool.


DPM cannot use space in any pre-existing volumes on disks added to the storage pool. Although a pre-existing volume on a storage pool disk may have free space, DPM can use only space in volumes that it creates. To make the entire disk space available to the storage pool, delete any existing volumes on the disk, and then add the disk to the storage pool.

To add disks to the storage pool

  1. In DPM Administrator Console, on the navigation bar, click Management, and then click the Disks tab.

  2. In the Actions pane, click Add.

    The Add Disks to Storage Pool dialog box appears. The Available disks section lists the disks that you can add to the storage pool.

  3. Select one or more disks, click Add, and then click OK.
