I have a server ( Windows 2003 ) running SQL Server DB and SSAS
We have 32GB of physical memory available
The DB and cubes are farly large 200GB DB's - 100GB cubes

What is the optimum size of the page file I should be using
I am aware that Microsoft recommend 1.5 * Phys RAM GB
( ie in my scemario 48GB page file would be recommended )

I am also aware that this recommendation relates to home PC's and not production servers running large SQL DB's

In practice this is too large as I am limited by local disk space - the alternative being to use a SAN drive which I dont want to do because of poor performance.

Is the 48GB really necessary ?
What would be the impact of reducing this and letting the physical RAM do the work ?
It has been suggested we reduce this page file to a very minimal size ie 1GB - what problems if any would this cause ?

We are trying to balance the slow read time of reading the disk for page file use whilst optimizing memory available for SQL services.

any thoughts?
