Physical Characteristics of the CRAY-2 Supercomputer
The CRAY-2 mainframe was elegant in appearance as well as in architecture. The memory, computer logic, and DC power supplies were integrated into a compact mainframe composed of 14 vertical columns arranged in a 300°arc.
The upper part of each column contained a stack of 24 modules and the lower part contains power supplies for the system. Total cabinet height, including the power supplies, was 45 inches, and the diameter of the mainframe was 53 inches. Thus, the "footprint" of the mainframe was a mere 16 square feet of floor space.
An inert fluorocarbon liquid circulated in the mainframe cabinet in direct contact with the integrated circuit packages. This liquid immersion cooling technology allowed for the small size of the CRAY-2 mainframe and was thus largely responsible for the high computation rates.
