Silicon Graphics Inc., or SGI, is one of the storied Silicon Valley names. Co-founded by Jim Clark (who later co-founded Netscape) in 1981, SGI was a pioneer in powerful desktop engineering workstations and, later, super-powerful servers. The company got hammered by Sun Microsystems and other competitors and became a shadow of its former self after the dot-com bust. It filed for bankruptcy in 2006, limped along in a zombie state, and then was picked up in May for about $25 million by Rackable Systems—which bought it out of a second bankruptcy proceeding. Rackable renamed itself Silicon Graphics International to squeeze the remaining brand equity out of the Silicon Graphics name. Mark Barrenechea, a former Oracle and CA executive who took over as CEO of Rackable in 2006, has the task of reviving a faded icon. “It’s humbling to have this incredible brand under my stewardship,” he told me recently.
