It's better to use 2x installed memory for Exchange as a starting point. Splitting the page file on separate physical disks should be OK as long as it is a total of 4 GB. Depending on the how much messaging activity you have you might want to bump up the memory to 4 GB and then the pagefile would need to obviously be increased substantially to about double the installed memory.

Check out this article for the Exchange memory settings. There are a few other tweaks in the registry. http://support.microsoft.com/kb/815372 Do you have any third-party apps running on your Exchange servers? I have seen memory leaks in third-party apps cause this kind of virtual memory issue. 2K3 Standard does allow 4GB on a drive. The way you have it set up with 2048 on two separate drives will give you a performance boost if they are actually separate physical disks or RAID sets. I have typically heard 1.5 times physical for virtual, but I don't think that is as much a best practice as a general rule of thumb. Depending on circumstances I have certainly set it lower or higher. 4 GB virtual should certainly be enough. Sorry for the random order of my answers. I also have trouble following directions and don't play well with others.

Colleagues, On two different Windows 2003 servers in as many weeks I have seen a popup when I logged in that says "Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied." On one server, I had 2048 pagefile on C. On the other, I had 4096 pagefile on C, but the note at the bottom of the screen showed only 2050. Both servers have 2Gb physical RAM, and both are Exchange 2003 servers. I have now put 2048 on C: and another 2048 on F: on both servers. So, I wonder if I have things set up right, so I have a few questions: 1. Isn't the pagefile limit in 2K3 Standard 4Gb per drive as I have read? Or is it actually 2Gb per drive? 2. With 2Gb physical RAM, isn't 4Gb pagefile the standard? 3. With the /3GB and /USERVA=3030 switches set, which is what I learned to do in class, why do I still get the Event Log error message that says "The memory settings for this server are not optimal for Exchange."? -- Larry Wahlers Concordia Technologies The Lutheran Church - Missouri Synod mailto:[EMAIL PROTECTED] direct office line: (314) 996-1876 List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/[email protected]/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/[email protected]/ ________________________________________________________________________ Check out the new AOL.
