An earlier clustering technology from Tandem that provided a high-speed interconnect architecture between subsystems in the mid-1990s. ServerNet I used switching technology to transfer data at 50 Mbytes/sec in both directions between CPUs, between I/O devices and between CPU and I/O. ServerNet II boosted speed to 125 Mbytes/sec. Originally used with Tandem's proprietary fault-tolerant computers, ServerNet became available for Windows NT clusters. See

Tandem's ServerNet Interconnect
Used for both MPP applications and SMP clusters, this conceptual diagram shows how ServerNet interconnected a high-speed switch between CPUs and I/O subsystems. The CPUs are purple; the disks are orange, and the green pipes are the ServerNet mesh. See
MPP and
SMP.
