Abstract

Methods and systems configured to interact with hardware components of a computer system are described. In some embodiments, the system includes a processor and a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions for generating, by a software module executing on the system, an Intelligent Platform Management Interface (IPMI) request configured for a controller of the computer system; transmitting, by the software module, the IPMI request to a server separate from the computer system, wherein the server is configured to emulate the controller of the computer system; and receiving, by the software module, an IPMI response from the server, wherein the IPMI response is based on a simulated operating condition of a hardware component of the computer system at the server, thereby obviating a manual adjustment of the hardware component on the computer system.

Claims

1. A system configured to monitor hardware components of a computer system, the system comprising a processor and a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions for

generating, by a software module executing on the system, an Intelligent Platform Management Interface (IPMI) request configured for a controller of the monitored computer system;

transmitting, by the software module, the IPMI request to a virtual IPMI server instead of the controller, wherein the virtual IPMI server is configured to act as a virtual controller for the monitored computer system to, based on the IPMI request, simulate an operating condition of a hardware component of the monitored computer system; and

receiving, by the software module, an IPMI response from the virtual IPMI server, wherein the IPMI response is based on the simulated operating condition of the hardware component of the monitored computer system at the virtual IPMI server, thereby obviating a manual adjustment of the hardware component on the monitored computer system.

2. The system of claim 1, wherein the memory is further configured to provide the processor with instructions for

receiving, by the software module, a user application inquiry from an operating system kernel executing on the monitored computer system, wherein the IPMI request is generated based on the user application inquiry;

generating, by the software module, a user application reply for the user application inquiry based on the IPMI response; and

delivering, by the software module, the user application reply to the operating system kernel.

3. The system of claim 2, wherein the memory is further configured to provide the processor with instructions for

registering the software module in the operating system kernel prior to the receiving of the user application inquiry.

4. The system of claim 3, wherein registering the software module comprises:

receiving network connection parameters for the virtual IPMI server;

initializing a network connection using the network connection parameters; and

configuring a request queue and a response queue associated with the request queue for the receiving of the user application inquiry and the delivering of the user application reply.

5. The system of claim 4, wherein receiving the user application inquiry comprises:

retrieving the user application inquiry from to the request queue; and

allowing the user application to complete the transmitting of the user application inquiry without waiting for the IPMI response from the virtual IPMI server.

6. The system of claim 5, wherein delivering the user application reply comprises:

storing the user application reply to the response queue associated with the request queue.

7. The system of claim 1, wherein the simulated operating condition of the hardware component is based on prior data collected by the controller when the hardware component was manually adjusted.

8. The system of claim 1, wherein the IPMI response is generated by the virtual IPMI server when the monitored computer system does not physically contain the hardware component.

9. The system of claim 1, wherein the memory is further configured to provide the processor with instructions for

upon detecting a setting to bypass the virtual IPMI server, transmitting, by the software module, the IPMI request to the controller;

and

receiving, by the software module, a controller response generated by the controller in response to the IPMI request.

10. A method for monitoring hardware components of a computer system, the method being performed in a system comprising a processor and a memory coupled with the processor, the method comprising:

generating, by a software module executing on the system, an Intelligent Platform Management Interface (IPMI) request configured for a controller of the monitored computer system;

transmitting, by the software module, the IPMI request to a virtual IPMI server instead of the controller, wherein the virtual IPMI server is configured to act as a virtual controller for the monitored computer system to, based on the IPMI request, simulate an operating condition of a hardware component of the monitored computer system; and

receiving, by the software module, an IPMI response from the virtual IPMI server, wherein the IPMI response is based on the simulated operating condition of the hardware component of the monitored computer system at the virtual IPMI server, thereby obviating a manual adjustment of the hardware component on the monitored computer system.

11. The method as recited in claim 10, further comprising:

preparing a database for storing raw data entries generated by the controller when the controller detects operating conditions occurring at the hardware component, wherein the raw data entries are used for generating the IPMI response.

12. The method as recited in claim 11, wherein receiving the IPMI response comprises:

fetching a sample raw data entry from the database corresponding to the hardware component under the operating condition; and

constructing the IPMI response based on the sample raw data entry.

13. The method as recited in claim 12, wherein receiving the IPMI response comprises:

altering the fetched sample raw data entry to simulate an abnormal operating condition occurring at the hardware component.

14. The method as recited in claim 12, wherein receiving the IPMI response comprises:

constructing the IPMI response to emulate the controller interacting with the hardware component, wherein the monitored computer system does not contain the hardware component.

15. A computer-readable storage medium, containing a set of instructions which, when executed by a processor of a system, cause the processor to perform a method for monitoring hardware components of a computer system, the method comprising:

generating, by a software module executing on the system, an Intelligent Platform Management Interface (IPMI) request configured for a controller of the monitored computer system;

transmitting, by the software module, the IPMI request to a virtual IPMI server instead of the controller, wherein the virtual IPMI server is configured to act as a virtual controller for the monitored computer system to, based on the IPMI request, simulate an operating condition of a hardware component of the monitored computer system; and

receiving, by the software module, an IPMI response from the virtual IPMI server, wherein the IPMI response is based on the simulated operating condition of the hardware component of the monitored computer system at the virtual IPMI server, thereby obviating a manual adjustment of the hardware component on the monitored computer system.

16. The computer-readable storage medium as recited in claim 15, wherein the software module contains
