Virtual memory low on Windows SBS 2003

We are running a Windows SBS 2003 and are low on virtual memory, our RAM is maxed out for what a 32-bit system can take advantage of.

I am under the impression that because our pagefile is on our C drive, I could create another pagefile on our D drive to alleviate this problem, or is that not true? the only pagefile we currently have is on C. C drive is also our OS partition and right now there is not really a lot of space free on the C drive. D is mainly used for storage.

Are there any potential problems in doing such a thing?

For best performance the pagefile should be on the same partition as the OS, unless the other partition is on a separate physical drive. If it is on the same physical drive there will be a performance penalty. How great a penalty depends on the nature of the workload and the current size of the pagefile. With some workloads you may not even notice the difference.

The pagefile is not simply used as overflow when RAM is exhausted. That would be a very bad idea. The pagefile is used on an ongoing basis to offload rarely used data, leaving more RAM for more important uses. This generally helps performance. It is only when the workload becomes so great that working data must be offloaded that performance really suffers.

Do not be deceived by a high value for "PF Usage" in Task Manager. This is not actually pagefile usage at all but the commit charge. Actual pagefile usage will typically be much lower.

You should be able to do this, but you will take a performance hit. While placing it on another HDD will help out, the Pagefile is not really meant to be relied on heavily as a memory source. I know this sounds terrible, but I'll say it: you should begin looking into either a 64 bit server system or a clustering system to relieve stress on that unit.

I hear you, from everything I have been reading the best thing would be for us to go to a 64-bit system, like you said. I was just hoping for a temporary solution to tide us over until that time.

Is the D Drive a logical partition on the same HDD or is it another physical drive?

Logical partition on the same HDD.

As a better temp solution, you could try adding another HDD and place the pagefile there. It might help you out more there.
