PC-CPU motherboards with common fault-tolerant power supply
DCFirst Claim
1. A computer system comprising:
- a multiplicity of PC-CPU motherboards, each of the multiplicity of PC-CPU motherboards includes a CPU processor having electrical circuitry interconnected with the processor, and a power-input connector connected to the circuitry for use in the supply of electrical power to power the respective motherboard;
an electrical power-supply means for affording fault-tolerating redundancy for supplying electrical power;
a mounting means for mounting the motherboards together with the power-supply means as a single unit; and
a wiring means for connecting the power-supply means n common to the power-input connectors of the motherboards for powering the motherboards in parallel with one another;
and wherein the power-supply means comprises a plurality of pairs of power-supply modules, means coupling the two power-supply modules of each said pair together for supplying power in parallel with one another and wherein the wiring means couples the pairs of power-supply modules together in parallel with one another for supplying power to the motherboards in parallel.

Abstract
Processor modules (2) are supported side-by-side with one another to slide in and out of a cabinet (1) on tracks (6, 7), each module (2) including a PC-CPU motherboard (11) and a hard-disk unit (16) mounted on a metal plate (3). Power is supplied to all the modules (2) in parallel from two power-supply units (18) mounted in the back of the cabinet (1), each comprising a pair of power-supply modules (19). The pairs of power-supply modules (19) supply power in parallel with one another to the processor modules (2). Diode circuitry (20) is included in each power-supply module (19) to isolate that power-supply module (19) from its paired power-supply module (19) in the event that a fault occurs by which the output voltage of the respective power-supply module (19) fall below that of the power-supply module (19) with which it is paired.
