You can also substitute custom volumes that you define in Disk Management for volumes in the
storage pool.
DPM can use any of the following for the storage pool:
• Direct attached storage (DAS)
• Fibre Channel storage area network (SAN)
• iSCSI storage device or SAN
The storage pool supports most disk types, including Integrated Drive Electronics (IDE), Serial
Advanced Technology Attachment (SATA), and SCSI, and it supports both the master boot
record (MBR) and GUID partition table (GPT) partition styles.
If you use a SAN for the storage pool, we recommend that you create a separate zone for the
disk and tape used on DPM. Do not mix the devices in a single zone.
You cannot add USB/1394 disks to the DPM storage pool.
We recommend that you use disks with capacity of no more than 1.5 terabytes. Because a
dynamic volume can span up to 32 disks, if you use 1.5-terabyte disks, DPM can create replica
volumes of up to 48 terabytes in size.
Important
Some original equipment manufacturers (OEMs) include a diagnostic partition that is
installed from media that they provide. The diagnostic partition might also be named the
OEM partition, or the EISA partition. EISA partitions must be removed from disks before
you can add the disk to the DPM storage pool.

Calculating Capacity Requirements
Capacity requirements for the DPM storage pool are variable and depend primarily on the size of
the protected data, the daily recovery point size, expected volume data growth rate, and retention
range objectives.
Daily recovery point size refers to the total size of changes made to protected data during a single
day. It is roughly equivalent to the size of an incremental backup. Retention range refers to the
number of days for which you want to store recovery points of protected data on disk. For files,
