AlphaServer GS80 utilizes a modular crossbar switch structure
AlphaServer GS80 uses either one or two system drawers as building blocks. Each drawer houses a Quad building block
(QBB) system module, which supports up to four CPUs, four memory modules, and eight PCI buses on a 7-GB/s non-
blocking backplane switch
Up to two system drawers are connected by a direct internal interconnect with 3.3-GB/s of bandwidth
