Sun Aims High With Constellation Blade-Based System: Page 3 of 3

The integrated switch was particularly impressive, because of its size. "There's a lot of rocket science that went into the design," Haff said. "The fact that [Constellation] is using a massively scaled InfiniBand switch is pretty impressive technology."

Blade servers are a growing segment of the server market. The hardware uses less space than tower and rack-mount servers, and can reduce maintenance and management costs. Blade servers slide into slots on a chassis, and can be easily replaced when they fail, or added if more horsepower is needed.

IBM led the worldwide general server market last year, followed by Hewlett-Packard. Sun, Dell, and others share a small segment of the total market.
