Hmm, I thought the 7000 series is Unisys-designed, but further research makes me uncertain. IBM nee Sequent has a serious effort going to get Linux running well on their 8- to 32-CPU boxes. The Unisys effort seems much more lackadaisical. IBM is looking to run single large database images (and whatnot) on theirs, while Unisys seems to be content doing server consolidation. So IBM is working on large SMP scaling issues, while Sequent is just adding the necessary BIOS/APIC/ppb support. Note that Unisys also supports Linux on their mainframe-hybrid boxes like the ClearPath: http://www.unisys.com/products/clearpath__servers/clearpath__plus__os__2200/models.htm -andy
