In Xp it is 2GB. Even if you have more in your machine. I am porting Unix
apps that required more. Will Vista be able to handle it? Also, is there a
prefered flavor of Vista for running apps like this... ie Business, ultimate,
etc.

Thanks
 
Sandman,

All depends on the version... 64 bit versions of Vista can do a lot more.

Vista Starter is limited one 32-bit microprocessor and up to 256MB of RAM.

Vista Home Basic, Home Premium, Home N, Professional, Professional N, Small
Business, Enterprise, and Ultimate Editions--will ship in both 32-bit (x86)
and 64-bit (x64) versions. All the home editions will support one processor,
and the business editions and Ultimate Edition support two.

Home Basic and Home N will be limited to 8GB of RAM.
Home Premium will support up to 16GB of RAM on both 32-bit and 64-bit PCs.
All the other versions support the maximum physical memory size on 32-bit
systems and up to 128GB of RAM on x64 systems.

There is a bunch of information on Memory Management in Windows Server 2003
SP1 and Vista/Longhorn here:
