The process began with creating a product specification and trade-off analysis for different approaches in the system architecture. The final architecture included an enclosure that was 6U high and provided the cooling for the 10 server blades. Built into three hot-swap power supplies, three hot-swap fan modules in the rear of the enclosure, (as well as a couple in the front), were designed to push more than enough air through the system to accommodate future capacity. The effective size of each server is 6 rack units, leading to a maximum of 70 servers in a 42U rack.

The 600ex enclosure also has a passive backplane which can be accessed not only by the blades, but by as many a four separate control modules that plug into the back. The test system contained two modules, one to actively manage the hardware and the second to provide pass-through from each servers network interfaces to a band of RJ45 connectors.

Risk analysis and mitigation plans were developed along with development on different thermal strategies to solve inherent cooling issues.
