In an effort to make its high-end Windows Datacenter product scale up and out even more than it does today, Microsoft is working on a new technology called Non-Uniform Memory Access (NUMA), which would speed Datacenter's data access on multiprocessor machines. Interestingly, this feature has been available in high-end UNIX systems for some time, but without any of the pretty graphics and Playskool-like administration tools. There's nothing like the sweet smell of progress.
