Abstract

Systems and methods for automatic throttling of resources in an information handling system are disclosed. A method may include determining whether a first throttling condition exists, the first throttling condition existing when a chassis management controller fails to communicate a clock or synchronization signal to one or more devices in an information handling system chassis for a particular duration of time. The method may also include determining whether a second throttling condition exists, the second throttling condition existing when the chassis management controller fails to communicate data to one or more devices in the information system handling chassis. The method may further include throttling a resource in the information handling system chassis if at least one of the first throttling condition and the second throttling condition exists.

21. A method for automatic throttling of resources in an information handling system chassis, comprising:

determining whether a first throttling condition exists, the first throttling condition existing when the resource is not in a low-power configuration;

determining whether a second throttling condition exists, the second throttling condition existing when an out-of-band command has been received to throttle the resource; and

throttling a resource in the information handling system chassis if at least one of the first throttling condition and the second throttling condition exists.

22. A method according to claim 21, further comprising:

determining whether a third throttling condition exists, the third throttling condition existing when a chassis management controller fails to communicate a clock or synchronization signal to one or more devices in an information handling system chassis for a particular duration of time; and

throttling the resource in the information handling system chassis if at least one of the first throttling condition, the second throttling condition, and the third throttling condition exists.

23. A method according to claim 21, further comprising:

determining whether a fourth throttling condition exists, the fourth throttling condition existing when the chassis management controller fails to communicate data to one or more devices in the information system handling chassis; and

throttling the resource in the information handling system chassis if at least one of the first throttling condition, the second throttling condition, and the fourth throttling condition exists.

24. A method according to claim 21, further comprising:

determining whether a fifth throttling condition exists, the fifth throttling condition existing when an electric current in the information handling system chassis has exceeded a predetermined threshold; and

throttling the resource in the information handling system chassis if at least one of the first throttling condition, the second throttling condition, and the fifth throttling condition exists.

25. A method according to claim 21, further comprising:

determining whether a sixth throttling condition exists, the sixth throttling condition existing when a command has been communicated by the chassis management controller to throttle the resource; and

throttling the resource if at least one of the first throttling condition, the second throttling condition, and the sixth throttling condition exists.

26. A method according to claim 21, wherein the resource includes a host, a processor, or a memory.

27. A method according to claim 21, wherein at least one of determining whether the first throttling condition exists and determining whether the second throttling condition exists includes monitoring a time division multiplexed (TDM) bus.

28. A system for automatic throttling of resources in an information handling system chassis, comprising:

at least one resource;

a throttle module communicatively coupled to at least one resource, the throttle module operable to;

determine whether a first throttling condition exists, the first throttling condition existing when the resource is not in a low-power configuration;

determine whether a second throttling condition exists, the second throttling condition existing when an out-of-band command has been received to throttle the resource; and

communicate a signal to throttle a resource if at least one of the first throttling condition and the second throttling condition exists.
