Abstract
An apparatus and system for throttling I/O devices in a computer system is provided. In an example, a method for throttling device power demand during critical power events. The method includes detecting a critical power event and issuing a signal to system devices to defer optional transactions during the critical power event.
Claims28
A method for throttling device power demand during critical power events, comprising:
- detecting a critical power event;
- and
- issuing a signal to system devices to defer optional transactions during the critical power event.
A system for controlling power usage, comprising:
- a power-fault detection system;
- a plurality of peripheral devices;
- and
- a control system, wherein the control system is configured to receive a signal from the power-fault detection system indicating a power fault and send a signal to the plurality of peripheral devices to defer optional transactions.
A system that throttles back power usage in peripheral devices in a computer system, comprising:
- a system management engine comprising:
- a power detection system;
- and
- an opportunistic buffer flush and fill (OBFF) controller;
- a signal line coupling the OBFF controller to a peripheral device;
- a communications bus coupling the OBFF controller to a second peripheral device;
- and
- a module comprising code configured to direct the system management engine to detect a power fault and issue an OBFF command to a coupled peripheral device.
A non-transitory, computer readable medium comprising code configured to control a node manager to throttle device power demand during critical power events, comprising:
- code configured to detecting a critical power event;
- and
- code to direct the node manager to issue a signal to system devices to defer optional transactions during the critical power event.
