CCSI's Clusteron™ represents a breakthrough in cooling technology for high density rack mounted servers. The Clusteron carries cool, fresh, outside air directly to each CPU, rather than recirculating heated air within the enclosure. This ensures thermally correct cooling of each CPU, and permits high density installations to operate at maximum speed 24/7. In today's high power, high density servers, the cooling is the technology that makes the difference.
The Clusteron rack enclosure brings the necessary fresh outside air to each chassis, and carries the heated air away, so that it cannot short-circuit back through another chassis. Fresh cool air enters the rack through the bottom and front. It is ducted to the front and left side of each chassis, and metered into the chassis. The hot air from the rear and right side of each chassis is sucked out and ducted up through the top of the enclosure, where it can then be removed from the room. The Clusteron is the only rack enclosure that ducts all incoming and exhaust air, and prevents them from mixing.
It is the designed-in integration of the Clusteron chassis and rack that provide the extreme cooling. The ducting in the rack brings the fresh cool air to each chassis, and removes the heated air. Each chassis completes this air-flow circuit by directing the fresh incoming air to the CPU's, and directing the heated air out of the chassis. Heated air is never allowed to be recirculated back over a CPU. Instead, fresh cool air is used, and this lowers CPU core temperature far below what would be possible using fans that recirculate the hot air. In the CCSI Clusteron, the CPU's operate at a far lower temperature than in other systems.
In the Clusteron, the design of the individual chassis is integrated with the design of the rack enclosure to provide the cooling solution. In each chassis, fresh cool air is sucked in through the front and left side, and ducted directly to the CPU's by a CCSI Wind Tunnel. Two blowers, (not fans), provide the force necessary to move the air through the sidewall resistance. The heated air from both the CPU's and the power supply is exhausted out the right side and rear of the chassis. This ensures that heated air is not blown back over a CPU. In this Quadra-Side™ cooling solution, air flow is directed through the chassis to ensure that hot components are always cooled by fresh air from outside the chassis.
