if anybody out there is a DBA, please give me some inputs on my question:

does the SQL server page virtual memory?
if it does, it is normal to some extend, but wouldn't it kill the performance if
too much paging?

when the memory maxed out, what other options if no more memory can be
added to the server? buy another server?

When SQL Server reaches the max memory it can use (either dynamically or configured), it starts swapping data pages to and from the disk subsystem.  If you are seeing constant indicators from PerfMon that your disks are getting hammered by SQL I/O requests, its time to upgrade some hardware.  (Very broad generalization, as there may be internal perf tuning that can be done as well)

Not sure how SQL Server affects the Windows Page file.  Probobly the same as any other 32-bit application

Thanks very much Kevin3NF.

But when it does the swapping and paging on constant basis,
it would affect the application and causes to crash, wouldln't it?

Only if it did it to the degree that the application started timing out.  SQL Server in itself cannot crash another application.
