The struggle within companies between their software and hardware business can lead to interesting co-opetition, and sometimes disaster. (A most extreme example being Sony’s ignominious fall from the top the portable music device heap as a result of its reluctance to disturb its music production arm’s legacy business). IBM, of course, is probably the canonical example, with its various partnerships with Microsoft ending up not only with Microsoft on top, but with its own PC hardware business suffering a long decline into oblivion as a result. Big Blue, presumably trying to avoid a replay, has entered into software licensing agreements with, among others, arch-rival Sun. Now, it seems they’re backing off on plans to offer Solaris support for GPFS, their shared disk cluster file system.
