Abstract

A method and apparatus for coordinating and authenticating requests for data. In one embodiment, the apparatus comprises: a baseboard management controller (BMC); and a request coordinator coupled to the BMC to intercept BMC requests and to provide intercepted requests to the BMC, where the coordination interface comprises a request parser to parse parameters for each of the BMC requests, one or more queues to store the requests while the BMC is servicing another BMC request, and a command submitter to send individual BMC requests to the BMC, wherein the BMC is operable to generate the responses to the BMC requests received from the coordination interface and to send the responses to the coordination interface.

Claims

one or more queues to store the requests while the BMC is servicing another BMC request, and

a command submitter to send individual BMC requests to the BMC,

wherein the BMC is operable to generate the responses to the BMC requests received from the request coordinator and to send the responses to the request coordinator;

authentication check logic to authenticate each of the one or more queued requests; and

an information forwarder to forward information received from the BMC in response to one request as a response to one or more other queued requests in one of the plurality of queues, wherein the information forwarder only forwards the information as the response to the one or more other queued requests for each of the one or more other queued requests that has been authenticated by the authentication check logic.

2. The apparatus defined in claim 1 wherein the one or more queues comprises a plurality of queues, wherein each of the plurality of queues stores requests having one or more matching parameters.

3. The apparatus defined in claim 2 further comprising data check logic to generate an indicator to specify whether a time the information is received from the BMC is within a timing completion threshold for other queued requests, and wherein the information forwarder only forwards the information as the response to the one or more other queued requests for the one or more other queued requests for which the indicator indicates the time the information is received is within the timing completion threshold.

4. The apparatus defined in claim 1 wherein the command submitter is operable to submit one BMC request at a time.

5. The apparatus defined in claim 4 wherein the command submitter is operable to receive one BMC request and determine if the BMC busy, and further wherein if the BMC is not busy, then the command submitter is operable to save a timestamp of the one request, send the one request to the BMC, and set an indicator that indicates the BMC is busy, the command submitter to set the indicator to indicate the BMC is not busy in response to receiving results of the servicing the request from the BMC.

6. The apparatus defined in claim 1 wherein one or more of the BMC requests are from a sensor interface.

7. A rack server system comprising:

a plurality of nodes, each of the nodes comprising;

a baseboard management controller (BMC) having one or more processors;

a request coordinator coupled to the BMC to intercept BMC requests received via a network interface and to provide intercepted requests to the BMC, the request coordinator comprising

a request parser to parse parameters for each of the BMC requests,

one or more queues to store the requests while the BMC is servicing another BMC request, and

a command submitter to send individual BMC requests to the BMC,

wherein the BMC is operable to generate the responses to the BMC requests received from the request coordinator and to send the responses to the request coordinator;

authentication check logic to authenticate each of the one or more queued requests; and

an information forwarder to forward information received from the BMC in response to one request as a response to one or more other queued requests in one of the plurality of queues, wherein the information forwarder only forwards the information as the response to the one or more other queued requests for each of the one or more other queued requests that has been authenticated by the authentication check logic.

8. The rack server system defined in claim 7 wherein the one or more queues comprises a plurality of queues, wherein each of the plurality of queues stores requests having one or more matching parameters.

9. The rack server system defined in claim 8 further comprising data check logic to generate an indicator to specify whether a time the information is received from the BMC is within a timing completion threshold for other queued requests, and wherein the information forwarder only forwards the information as the response to the one or more other queued requests for the one or more other queued requests for which the indicator indicates the time the information is received is within the timing completion threshold.

10. The rack server system defined in claim 7 wherein the command submitter is operable to submit one BMC request at a time.

11. The rack server system defined in claim 10 wherein the command submitter is operable to receive one BMC request and determine if the BMC busy, and further wherein if the BMC is not busy, then the command submitter is operable to save a timestamp of the one request, send the one request to the BMC, and set an indicator that indicates the BMC is busy, the command submitter to set the indicator to indicate the BMC is not busy in response to receiving results of the servicing the request from the BMC.

12. The rack server system defined in claim 7 wherein one or more of the BMC requests are from a sensor interface.

13. A method comprising:

receiving, via a coordination interface, baseboard management controller (BMC) requests that are for a BMC, the coordination interface being outside of the BMC and the BMC requests being received via a network interface;

parsing parameters for each of the BMC requests;

storing the requests in one or more queues while the BMC is servicing another BMC request using one or more processors of the BMC;

submitting individual BMC requests to the BMC for servicing when the BMC is no longer servicing another BMC request;

receiving responses to the BMC requests from the BMC at the coordination interface;

sending, via the coordination interface, the responses to the coordination interface;

authenticating each of the one or more queued requests; and

forwarding information received from the BMC in response to one request as a response to one or more other queued requests in one of the plurality of queues, wherein forwarding information received from the BMC in response to one request as a response to one or more other queued requests in one of the plurality of queues only occurs for each of the one or more other queued requests that has been authenticated.

14. The method defined in claim 13 wherein storing the requests in one or more queues while the BMC is servicing another BMC request comprises storing the requests in a plurality of queues, wherein each of the plurality of queues stores requests having one or more matching parameters.

15. The method defined in claim 14 further comprising generating an indicator to specify whether a time the information is received from the BMC is within a timing completion threshold for other queued requests, and wherein forwarding information received from the BMC in response to one request as a response to one or more other queued requests in one of the plurality of queues only occurs for the one or more other queued requests for which the indicator indicates the time the information is received is within the timing completion threshold for the one or more other queued requests.

16. The method defined in claim 13 further comprising:

determining if the BMC busy prior to forwarding one request of the BMC requests to the BMC;

saving a timestamp of the one request prior to sending the one request to the BMC;

setting an indicator that indicates the BMC is busy so no additional requests are forwarded to the BMC while the BMC services the one request; and

setting the indicator to indicate the BMC is not busy in response to receiving results of servicing the one request from the BMC.

17. The method defined in claim 13 wherein one or more of the BMC requests are related to a sensor.

18. An article of manufacture having one or more non-transitory computer readable media storing instructions which, when executed by a system, cause the system to perform a method comprising:
