ABSTRACT:
FIELD OF INVENTION
This invention relates to computer systems and hardware, and in particular to a radial computer system, hardware for building a radial computer system and a method for building a radial computer system.
BACKGROUND
Scalable computer systems typically have an increased number of computer elements which typically require a greater number of cable connections within the computer system. Scalable computer systems typically also require longer cable lengths. Cables are typically expensive high frequency cables. The performance of the computer system may be degraded by increased cable lengths and an increased number of connections causing additional electromagnetic interference. In some cases, scalable computer systems also require additional cooling hardware beyond what has been used in the past to keep the larger number of computer elements at the appropriate operating temperature. These factors make the building of scalable computer systems less desirable. As computer use grows and as the size of computer systems increase, new hardware and methods are needed to provide for the necessary cable connections between elements of the computer system and to provide for the additional cooling hardware required by the larger systems.
DISCLOSURE OF INVENTION
According to one aspect of the invention, a plurality of computer elements are aligned by joiners so that the computer elements form an arc with an inner radius and an outer radius. The radial alignment maintains minimal space between computer elements along the inner radius of the arc and increases space between computer elements toward the outer radius of the arc. According to one aspect of the invention, high frequency cables are routed from element to element through the joiner proximal the inner radius of the arc. According to another aspect of the invention, at least one bulkhead is mounted in the space between the computer elements distal from the inner radius of the arc but within the outer radius of the arc. The bulkhead includes a plate for receiving cable connections on each side of the plate. According to another aspect of the invention, both the joiner and the bulkhead include features for providing electromagnetic interference shielding.
The radial configuration of the cluster and the radial hardware resolve problems typically associated with scalable computer systems, providing a computer system that reduces high speed cable lengths, provides additional connection points for the increased number of cable connections, provides electromagnetic interference shielding, and provides additional space for cooling hardware. These features result in an improved scalable computer system. The various embodiments of the invention provide a radial computer system, hardware for a radial computer system and a method for building a radial computer system
