I read an article in PC World magazine about how Vista uses all available memory on a box. Which as the article pointed out is a good thing because it has the memory processes immediatley available to use when needed. Does server 2008 organize its memory usage along the same lines? Just curious because this is a fact that sold me on upgrading to Vista.

Hi, Yes. Windows Server 2008 organizes its memory allocation as the same way with Windows Vista. In Windows Server 2008, the allocation of physically memory is greatly enhanced. Requests to allocate contiguous memory are much more likely to succeed because the memory manager now dynamically replaces pages, typically without trimming the working set or performing I/O operations. In addition, many more types of pagessuch as kernel stacks and file system metadata pages, among othersare now candidates for replacement. Consequently, more contiguous memory is generally available at any given time. In addition, the cost to obtain such allocations is greatly reduced.
