IBM SP Switch

IBM's first-generation SP Switch fabric connecting ASCI Blue-Pacific's RS/6000 SP nodes, predating SP Switch2.

Why this part

The switch generation IBM shipped before SP Switch2, the fabric ASCI White used two years later; the two are easy to conflate since IBM kept the SP Switch name for both. Blue-Pacific marks one of the last big deployments of this first-generation fabric before IBM roughly doubled its bandwidth for the Power3 generation.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
