No matter how hard they blow...
No matter how hard they blow, they can't turn a dog turd into a balloon.
SGI spiraled down the porcelain throne. Rackable was bleeding red and heading for the great whirlpool as well. Joining the two isn't going to cure the flu they each have. It is just going to require a plunger and some elbow grease when they finally reach the bottom of the bowl.
SGI had their own processor technology (Mips), and was a pioneer in 64-bit computing. In their heyday they were amazing, a real technology pioneer and serious computing and visualization player. Once they ditched their own processor architecture for Intel's they became nothing more than a technicolor Supermicro. As for Rackable, their major feat was shorty 2U chassis in a rack and using DC power. Compared to SGI's once having a processor architecture, Rackable is a helmet wearing short bus commando with a drool bucket.
Both of them seem to excel at blowing cash like an undersexed, alcoholic trust fund kid in Vegas.
