DPM uses disk as the primary short-term storage location, whilst allowing long-term storage using tape. A DPM storage pool is a collection of disks that DPM uses to store replicas and recovery points for protected data. DPM requires at least one disk in the storage pool before it can begin protecting data. Additional disks can be added to the storage pool as necessary.
To add a disk to the DPM storage pool, perform the following steps:
1. In the Management workspace of the DPM console, click Disks.
2. On the ribbon, click Add. This will launch the Add Disks To Storage Pool dialog box. The disks must be online and initialized before you can add them to the DPM storage pool. Figure 1 shows two disks being added to the storage pool.

3. Click OK to add the disks to the storage pool. DPM will convert any disk you add to dynamic, and convert any volumes to simple volumes. Best practice is to allocate new, unformatted, empty disks to the storage pool, and allow DPM to manage and prepare them. Figure 2 shows two disks added to the DPM storage pool.
