Note

Memory usage for the DPM instance of the SQL Server service

(Microsoft$DPM$Acct.exe) is expected to be comparatively high. This does not indicate a

problem. The service normally uses a large amount of memory for caching, but it

releases memory when available memory is low.

How DPM Operations Affect Performance

DPM and Memory

When the memory in use by all the existing processes exceeds the amount of RAM available, the

operating system will move pages (4-KB pieces) of one or more virtual address spaces to the

computer’s hard disk, freeing that RAM for other uses. In Microsoft Windows systems, these

pages are stored in one or more files, called pagefile.sys, in the root of a partition.

DPM requires a pagefile size that is 0.2 percent the size of all recovery point volumes combined,

in addition to the recommended size (generally, 1.5 times the amount of RAM on the computer).

For example, if the recovery point volumes on a DPM server total 3 TB, you should increase the

pagefile size by 6 GB.

For information about modifying the pagefile size, see "

" (http://go.microsoft.com/fwlink/?LinkId=95116).

There is a Volume Shadow Copy Service (VSS) non-paged pool limitation on x86 32-bit operating

systems. Therefore, if you are protecting more than 10 TB of data, the DPM server must be

running on a 64-bit operating system.

Managing Performance

Performance Counters

One method you can use to monitor DPM server performance is Performance in Administrative

Tools. You can configure the monitored data to be saved as a log. You can also configure

Performance to generate alerts. For information about how to create and configure performance

alerts, see Microsoft Knowledge Base article 324752,

, (http://go.microsoft.com/fwlink/?LinkId=47881).

Note

You can use the DPM Management Pack for Microsoft Operations Manager 2005 (MOM)

or System Center Operations Manager 2007 to centrally monitor the state, health, and

performance of multiple DPM servers from an Operations Management server. For
