Abstract

In one embodiment, a method for increasing power efficiency for an information handling system includes: monitoring, by a host service, one or more performance metrics associated with a memory device of the information handling system, the memory device including a power controller communicably coupled to a management device via a side-band bus; predicting, by the host service, an energy requirement for the memory device based on the one or more performance metrics; generating, by the host service, a power configuration profile based on the energy requirement, the power configuration profile indicating one or more power controller parameters associated with the power controller; sending, by the host service, the power configuration profile to the management device; receiving, by the management device, the power configuration profile; and modifying, by the management device and via the side-band bus, the one or more power controller parameters based on the power configuration profile.

First claim

What is claimed is:

1. A method for increasing power efficiency for an information handling system, the method comprising:
monitoring, by a host service of a processor subsystem of the information handling system, one or more performance metrics associated with a memory device of the information handling system, the memory device including a power controller communicably coupled to a management device of the information handling system via a side-band bus;
predicting, by the host service, an energy requirement for the memory device based on the one or more performance metrics;
generating, by the host service, a power configuration profile based on the energy requirement, the power configuration profile indicating one or more power controller parameters associated with the power controller, the one or more power controller parameters including one or more switching frequencies for the power controller;
sending, by the host service, the power configuration profile to the management device;
receiving, by the management device, the power configuration profile;
identifying, by the management device, an output voltage of a voltage regulator of the information handling system, the voltage regulator communicably coupled to the power controller;
determining, by the management device, that the output voltage is outside of an operating temperature threshold; and
in response to determining that the output voltage is outside of the operating temperature threshold, modifying, by the management device and via the side-band bus, the one or more power controller parameters based on the power configuration profile to cause an increased power efficiency for the information handling system, including stepping-up and/or stepping-down the one or more switching frequencies for the power controller such that the power controller experiences minimal switching losses and such that the power controller and memory device experience a decreased heat dissipation.

2. The method of claim 1 , wherein modifying the one or more power controller parameters comprises:
accessing, by the management device, a memory of the power controller via the side-band bus; and
storing, by the management device, one or more commands associated with the power configuration profile into the memory of the power controller.

3. The method of claim 1 , wherein modifying the one or more voltage regulator parameters comprises:
accessing, by the management device, a memory of the voltage regulator via the side-band bus; and
storing, by the management device, one or more commands associated with the power configuration profile into the memory of the voltage regulator.

4. The method of claim 1 , wherein monitoring the one or more performance metrics associated with the memory device comprises:
accessing, by the host service, one or more performance counters associated with the memory device; and
determining, by the host service, a memory usage of the memory device based on the performance counters, the memory usage indicating a frequency in which the memory device is accessed.

5. The method of claim 1 , wherein monitoring the one or more performance metrics associated with the memory device comprises:
accessing, by the host service, one or more memory banks of the memory device; and
determining, by the host service, a memory usage of the one or more memory banks, the memory usage indicating a frequency in which the memory device is accessed.

6. The method of claim 1 , further comprising:
modifying, by the host service and via the side-band bus, the one or more power controller parameters based on the power configuration profile, wherein modifying the one or more power controller parameters comprises:

monitor, by a host service of a processor subsystem of an information handling system, one or more performance metrics associated with a memory device of the information handling system, the memory device including a power controller communicably coupled to a management device of the information handling system via a side-band bus;
predict, by the host service, an energy requirement for the memory device based on the one or more performance metrics;
generate, by the host service, a power configuration profile based on the energy requirement, the power configuration profile indicating one or more power controller parameters associated with the power controller, the one or more power controller parameters including one or more switching frequencies for the power controller;
send, by the host service, the power configuration profile to the management device;
receive, by the management device, the power configuration profile;
identify, by the management device, an output voltage of a voltage regulator of the information handling system, the voltage regulator communicably coupled to the power controller;
determine, by the management device, that the output voltage is outside of an operating temperature threshold; and
in response to determining that the output voltage is outside of the operating temperature threshold, modify, by the management device and via the side-band bus, the one or more power controller parameters based on the power configuration profile to cause an increased power efficiency for the information handling system, including stepping-up and/or stepping-down the one or more switching frequencies for the power controller such that the power controller experiences minimal switching losses and such that the power controller and memory device experience a decreased heat dissipation.
