Abstract

The present invention discloses a method for managing voltage supply in multiple linked systems. The method may comprise the steps of connecting a plurality of digital data processing elements and a plurality of power supplies into at least two power domains, each of the domains having at least one processing element and at least two power supplies; monitoring a supply of electrical power to the at least two power domains; sensing a drawn current drawn from associated power supplies; sensing a loss of electrical supply to associated power supplies; 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 another domain which has capacity to support the domain with an outage.

Claims (7)

1. 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 a supply of electrical power to the at least two power domains;

sensing a drawn current drawn from associated power supplies;

sensing a loss of electrical supply to associated power supplies; 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 another domain which has capacity to support the domain with an outage;

said responding to a sensed outage comprises determining a capability of interconnected power supplies to supply a required current by associated processing elements supplied by a power supply which has lost electrical supply and, in the event that the interconnected power supplies are incapable of continuing current supply, limiting the interval of time during which current is supplied to said associated processing elements supplied by the power supply which has lost electrical supply.
