I would not exactly call this article news - these boxes have been around awhile... available today with the Quad Core Intel CPU's and being shipped in 5 days.

The X2250 comes in a variety of off-the-shelf options.

The article says, "The Sun Fire X2250 and X4250 machines are your go-to units for a wide variety of jobs, including hardcore stuff like HPC"

The HPC Market will probably not be interested in these servers.

Real HPC users would request SUN to include pack the new Intel CPU in the 42U high 48 blade Sun Blade 6048 Chassis. The 6048 integrates well into the SUN Constellation - providing exceptional performance, superior cable reduction, fast modular assembly, and a better price point better with similar features than anyone else in the industry.

HPC users would most likely tack in SUN's Open Source Lustre file system, since this is the file system used by most HPC clusters implemented globally.
