Abstract
In a data processing system having elements grouped into a plurality of power domains, each one of which has at least one processing element and at least two power supplies, power domains are interconnnected by sensing and switching circuitry which senses the conditions of power supply and demand in and among the domains and switches from one domain to power supplies in another domain in the event of failure in the first domain.
Claims15
Apparatus comprising:
- a plurality of digital data processing elements;
- a plurality of power supplies;
- said processing elements and said power supplies being interconnected to define at least two power domains, each of said domains having at least one processing element and at least two power supplies;
- and
- sensing and switching circuitry operatively connected with said power domains to sense the conditions of power supply from said power supplies to said processing elements and to respond to a sensed outage of one of said power supplies by switching excess power capacity available from a fully functional domain to a domain having a sensed power shortage.
2 more elements
Method comprising:
- connecting a plurality of digital data processing elements and a plurality of power supplies into at least two power domains, each of said domains having at least one processing element and at least two power supplies;
- monitoring the supply of electrical power to the domains;
- and
- responding to a sensed outage of one of said power supplies by switching power supply for a domain in which there is a sensed outage to a domain which has capacity to support the domain with an outage.
