HP GS80 - Manual (Page 2)

Processor Processor Processor Processor Up to eight Alpha 21264 6/1224-MHz CPUs (one CPU per module)
Cache Memory Cache Memory Cache Memory Cache Memory 64-K I and D caches on-chip; 16-MB ECC on-board cache per CPU
Architecture Architecture Architecture Architecture 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
