DPM 2007 Recommendation

DPM Server Hardware Requirements

We recommend that you install DPM on a 64-bit machine.

Component	Recommended Requirement
Processor	· 2.33 GHz Quad
Memory	· 4 GB RAM
Pagefile	N/A
Disk space for DPM installation	· 2–3 GB of free space on the program files volume Note DPM requires a minimum of 300 MB of free space on each protected volume for the change journal. Additionally, before archiving data to tape, DPM copies the file catalog to a DPM temporary installation location; therefore, we recommend that the volume on which DPM is installed contains 2–3 GB of free space.
Disk space for storage pool Note The storage pool does not support Universal Serial Bus (USB)/1394 disks.	· 2–3 times the size of the protected data
Logical unit number (LUN)	· Maximum of 17 TB for GUID partition table (GPT) dynamic disks · 2 TB for master boot record (MBR) disks Note These requirements are based on the maximum size of the disk as it appears to the Windows Server operating system.

Disk type Supported by DPM 2007

• DPM 2007 supports using any of the following sources for server storage capacity:
  • Direct attached storage (DAS)
  • Fibre Channel storage area network (SAN)
  • Internet SCSI (iSCSI) storage device or SAN; the iSCSI target must have received Windows Hardware Certification

Note  : The storage pool supports most disk types, including Integrated Drive Electronics (IDE), Serial Advanced Technology Attachment (SATA), SCSI, and supports both the master boot record (MBR) and GUID partition table (GPT) partition styles.

• DPM 2007 does not support USB/1394 disks

How much data can I protect with DPM 2007?

Following are the data source limits that DPM 2007 can protect and the recommended disk space required per DPM server. These recommendations assume that you meet the DPM server minimum hardware requirements.

 

Platform	Data Source Limit	Recommended Disk Space
32-bit computers	· 150 data sources We recommend approximately 50 servers and 75 clients fanning into a single DPM server.	· 10 TB Note There is a Volume Shadow Copy Service (VSS) non-paged pool limitation on x86 32-bit operating systems. If you are protecting data using a secondary DPM server, the recommended disk space is only 6 TB.
64-bit computers	· 300 data sources Data sources are typically spread across 75 physical servers or 150 client computers.	· 40 TB

Note

The actual number of computers and how much data DPM can protect will vary depending on the total amount of data you want to protect, and the change rate of the data. For example, a single DPM server could potentially protect 300 servers with single volumes and low change rates.
