ServerNet

ServerNet

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 clustering, SAN and Tandem.

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. (Image courtesy of Tandem Computers Incorporated.)
