Dual computers boost system performance

General Micro Systems V469 Patriot Many aerospace and military applications require redundant or parallel processors to achieve extended availability requirements while meeting performance goals. So why not include redundant hardware on a single board?

General Micro Systems has done just that with the V469 Patriot, a new VXS (VME switched serial), dual-processor, single-board computer that claims to provide higher "horsepower density" per watt than any other current technology. Unlike other dual-processor boards, the Patriot utilizes two independent M-760 Pentium-M processors that offer 100% redundancy, including power, cooling, and I/O.

Each half operates at 2.0 GHz and has its own Fibre-Channel connection with boot capability. The two halves communicate via a direct Gigabit-Ethernet link. Support for the board is available under Windows XP/2000, VxWorks-Tornado II, and Linux. Pricing starts at $4700 (100).
