I've got a SS 2000 SP4 server in a warehouse environment that is doing a lot
of paging. It has many periods of 10-20 minutes where SS Buffer Cache Hit
Ratio stays below 90% for example.
The server has 8G of physical RAM and we've got the page file set at 8.2G
per MS. The MS engineer recommended setting it at basically 12M over physical
RAM.
So here's my problem: we want to add memory to the server but the server
really does not have much disk space on the internal drive and it's an older
server so expanding the drives is probably not practical.
So, for example, if we add 8G giving us a total of 16G of RAM, I can't
expand the page file to 16.5G.
So the Win Admin's idea was to add a huge amount of physical RAM to the
server, like say 24G additional, so that the server will basically never page
and then we don't have to worry about expanding the page file.
Is this a reasonable approach? Can you just flood the server with RAM and
assume it will never page?

I would not like to say it will never use page file. But adding more RAM will definitely reduce the use of page file.
My understanding is that the purpose of using page file is to reduce the cost since RAM is much more expensive than hard disk.
