Abstract

An Incremental Power System for a computer system consists of defining a bulk supply capability at a high enough voltage level to obtain efficient regulation from switched mode on card regulators at an incremental current necessary to supply the entr minimum configuration systems needs, and replicating that bulk supply in whatever quantity is necessary to supply the maximum configuration system's need. This is followed by identifying the increments of growth at which the customer is required to add bulk supplies between the entry and maximum systems. If incremental redundancy is allowed as part of the system definitio the packaging of the bulk supplies is allocated to enable the addition of one bulk supply to the maximum number defined above.

Incremental Power System

An Incremental Power System for a computer system consists of defining a bulk supply capability at a high enough voltage level to obtain efficient regulation from switched mode on card regulators at an incremental current necessary to supply the entr minimum configuration systems needs, and replicating that bulk supply in whatever quantity is necessary to supply the maximum configuration system's need. This is followed by identifying the increments of growth at which the customer is required to add bulk supplies between the entry and maximum systems. If incremental redundancy is allowed as part of the system definitio the packaging of the bulk supplies is allocated to enable the addition of one bulk supply to the maximum number defined above. The remainder of the incremental power definition consists of identifying the on card regulator requirements of each card or device function in the system. This consists of defining the current requirement at each voltage for each card and/or function, selecting a regulator capable of supplying that current voltage, and allocating the space on the card to package the necessary regulators. Three major advantages accrue from the on card regulators: 1. tighter regulation at the load, 2. reduced distribution effects, and 3. increased reliability at the load.

From the above it is seen that an Incremental Power System provides the following advantages over a Centralized Power System: 1. decreased entry and average systems cost, 2. decreased distribution losses with improved regulation at the load, 3. decreased power generated to accommodate losses, 4. no dummy loads are ever required, 5. reduced cabling complexity for distributing power, 6. potential for battery back-up without UPS expense, 7. potential for low cost K of N redundancy, and 8. the potential to separate the power cooling from logic cooling.
