This question has come up in the last hour or so with one of my customers and I thought it was worth mentioning as a reminder.

The recommend page file size for an Exchange server is 1.5x memory up to a maximum size of 4095Mb.  For example, if you have 1Gb RAM, we would recommend a page file size of 1.5Gb.

If you have the maximum RAM that Exchange can utilize (4Gb), the page file size should be 6Gb.  As we have a limitation on the page file size, you will need to create a second page file on a different volume.

From a performance perspective, it is recommend to have each page file on a seperate physical volume.

For more information, these two articles are particularly interesting:

Configuring page files for optimization and recovery in Windows Server 2003, in Windows 2000, and in Windows NT

and

Page file size is too small

I was talking to one of the Technical Account Managers (TAMs) yesterday regarding a customer and their Exchange Ops guide and if I could add anything to the current document.  He was particularly interested in any kind of "top 10" that could be incorporated.

Well, after having a look around KB I found this article which contains some very useful information.

Welcome to my new Technet blog.  I've been blogging for a while over on MSDN and I will be mirroring that here, though perhaps in the future I'll decide to migrate over, we'll see. 

Anyway, a little bit about me.  My name is James Whelan and I work for Microsoft UK.  I've been at Microsoft for around 6 1/4 years and started off in Product Support Services (PSS) as an Exchange/Outlook engineer.  I did that role for around 2 1/2 years before I moved over to my current role, which is a Rapid Response Engineer in March 2003.  I've travelled all over Europe, and perhaps some of you reading this have met me.  In the New Year, I'll be taking up a new role as a Technical Lead in the Microsoft Partner Program.  It is a going to be a massive challenge and one which I am very excited about.

I hope you enjoy the blog.  I welcome all comments and feedback.

I've just signed up to Technorati, you can check out my profile there, though it needs a bit of work.

Thanks & take care,

James.
