Choosing Sources for Storage Capacity

DPM can use any of the following for storage pool capacity:

  • 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 supports both the master boot record (MBR) and GUID partition table (GPT) partition styles.

The storage pool does not support USB/1394 disks.

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.
