Which disk volume should I use for the page file on my Exchange Server 2003?

I'm running Exchange Server 2003 on a Dell PowerEdge 1800.  Using a RAID5 with two logical volumes:  C: as the system volume and D: for the data.

Unfortunately, I've run out of space on the system volume.  To free up space, I've split the page file between the system volume and the data volume.  My question:  can I safely put the entire page file on the data volume (i.e. not have any page file on the system volume)?  I'm mostly concerned about performance.

You can very well do that.  One consequence would be.. in a unlikely situation of system crash, the memory dump will not get generated if your page file is not in the boot partition.

As they are both RAID5 is not going to make much noticable difference either way - Ideally it should be on a seperate drive (non RAID5) all together.

That's what I thought.  Thanks for the feedback.

I would suggest you have a look over my page on Boot Drive Size - especially if you're running low on space on C:.


(And I agree with KCTS - it's not going to make a difference in performance - to have an impact on performance, the pagefile needs to be on a different set of spindles)

Thanks, Lee.
Regarding page file size, Microsoft referred me to a TechNet article:

It seems to suggest a size of 1.05 x size of physical memory.  And a maximum of 4095.  Your thoughts?
Lee W, MVPTechnology and Business Process AdvisorCommented:
If you read the intro to the article, those recommendations are for specific circumstances.  In general, the recommendation is 1.5x RAM for a Windows Server.  In addition, it does say a maximum of 4095 PER VOLUME - so if you have multiple disks or partitions, it's possible to create multiple pagefiles, each at 4095 MB.  The trick is that a pagefile cannot reach 4 GB on any single partition.
