Page file setup for Windows Servers

Lots of the customer, even our internal staff is asking, what is the proper page file should we set for the servers? Should we let the Windows set for us automatically?

To answer this, Paging file is the process where transfering data from the physical memory to the system.

By default, if the operating system fails, it will copy everything in memory to a .dmp file, so, to be able to get the information in the physical memory, you must have a paging file size that larger than the physical amount of memory you have, plus some space to gather the data.

Example, if your machine has 4GB ram, your page file should set more than 4GB, eg: 4.1GB.

What is the recommendation? In NT4 days, we will recommend the two times of your physical memory, but with the latest hardware as for now, we will recommend physical memory + 10MB - which we get this info from TechNet.
