Abstract

An information handling system includes a memory and a controller. The memory stores settings for components within the information handling system. The controller can communicate with the memory. The controller detects a presence of a module, receives parameters of the module from the module, determines information for the module based on the parameters of the module, and updates the settings for the components based on the information for the module.

First claim

What is claimed is:

1. An information handling system comprising:
a memory to store settings for components within the information handling system; and
a controller configured to communicate with the memory, the controller to detect a presence of a module, to receive parameters of the module from the module, to determine information for the module based on the parameters of the module, wherein the information includes particular locations within the module that include components that can affect the air flow though the module and the information handling system, and to update the settings for the components of the information handling system based on the information for the module, to cross reference a cooling tier with a fan solution for a cooling fan, to determine a scaling factor for an open loop fan curve of a fan control setting based on the cross reference of the cooling tier with the fan solution, and to update fan control settings based on the scaling factor for the open loop fan curve.

2. The information handling system of claim 1 , wherein the information includes the cooling tier for the module.

3. The information handling system of claim 1 , the controller to update the fan control settings based on the information for the module and a configuration of the information handling system.

4. The information handling system of claim 3 , wherein the module is a component plugged within the information handling system.

5. The information handling system of claim 1 , wherein the module is connected to an external panel of the information handling system.

6. The information handling system of claim 1 , further comprising:
a thermal table to store the settings for the components, the controller to update the settings retrieved from the thermal table based on the information for the module.

7. The information handling system of claim 1 , wherein the information for the module is selected from a group including fan population details, ambient sensor corrections, a module specific zoning policy, airflow sensor correlations and targets, normalized open loop cooling requirements, airflow tier, normalized fan vibration limits, thermal scaling factor, hardware and sensor presence, chassis airflow correlation, redefined power cap settings, and redefined fresh air configurations.

8. A method comprising:
controlling, by a controller of an information handling system, a speed of a cooling fan based on fan control settings;
detecting, by the controller, a presence of a module associated with the information handling system;
receiving, from the module, parameters of the module;
determining information for the module based on the parameters of the module, wherein the information includes particular locations within the module that include components that can affect the air flow though the module and the information handling system;
updating, by the controller, the fan control settings based on the information for the module;
cross referencing the cooling tier with a fan solution for the cooling fan;
determining a scaling factor for an open loop fan curve of the fan control setting based on the cross reference of the cooling tier with the fan solution; and
updating the fan control settings based on the scaling factor for the open loop fan curve.

9. The method of claim 8 , wherein the information includes a cooling tier for the module.

10. The method of claim 8 , further comprising:
updating the fan control settings based on the information for the module and a configuration of the information handling system.

11. The method of claim 8 , wherein the module is a component plugged within the information handling system.

12. The method of claim 8 , wherein the module is connected to an external panel of the information handling system.

13. The method of claim 8 , further comprising:
storing, by the controller, the fan control settings in a thermal table of the information handling system.

14. The method of claim 8 , wherein the information for the module is selected from a group including fan population details, ambient sensor corrections, a module specific zoning policy, airflow sensor correlations and targets, normalized open loop cooling requirements, airflow tier, normalized fan vibration limits, thermal scaling factor, hardware and sensor presence, chassis airflow correlation, redefined power cap settings, and redefined fresh air configurations.

15. A method comprising:
controlling, by a controller of an information handling system, settings for components within the information handling system;
detecting, by the controller, a presence of a module associated with the information handling system;
receiving, from the module, parameters of the module;
determining information for the module based on the parameters of the module, wherein the information includes particular locations within the module that include components that can affect the air flow though the module and the information handling system;
updating the settings for the components of the information handling system based on the information for the module;
cross referencing a cooling tier with a fan solution for a cooling fan;
determining a scaling factor for an open loop fan curve of a fan control setting based on the cross reference of the cooling tier with the fan solution; and
updating fan control settings based on the scaling factor for the open loop fan curve.

16. The method of claim 15 , further comprising:
updating fan control settings based on information for the module and a configuration of the information handling system.

17. The method of claim 15 , wherein the module is a component plugged within the information handling system.

18. The method of claim 15 , wherein the module is connected to an external panel of the information handling system.
