Abstract

An information handling system and method provide for receiving, at an information storage device, a specification of reporting criteria for a plurality of information storage device parameters, receiving a specification of logical relationships for the reporting criteria, monitoring information storage device parameter values for the information storage device parameters, comparing the information storage device parameter values to the reporting criteria to obtain indications of whether the reporting criteria have been satisfied, applying the logical relationships to the indications, and, in response to the logical relationships applied to the indications yielding a first result, transmitting an alert notification including information storage device parameter values in the form of a single contiguous message for which a corresponding command to send the single contiguous message has not been received by the information storage device.

Claims

1. An information handling system comprising:

a processor;

a memory communicatively coupled to the processor; and

an information storage device communicatively coupled to the processor via an input/output (I/O) bus for communicating I/O data between the processor and the information storage device, the information storage device configured to receive a specification of reporting criteria for a plurality of information storage device parameters, to receive a specification of logical relationships for the reporting criteria, to monitor information storage device parameter values for the information storage device parameters, to compare the information storage device parameter values to the reporting criteria to obtain indications of whether the reporting criteria have been satisfied, to apply the logical relationships to the indications and, in response to the logical relationships applied to the indications yielding a first result, to transmit an alert notification to the processor, the alert notification including the information storage device parameter values.

2. The information handling system of claim 1, wherein, when traffic is present on the I/O bus, the alert notification comprising the information storage device parameter values is included as part of a return status being sent from the information storage device to the processor in response to a command issued by the processor to the information storage device, and, when traffic is not present on the I/O bus, a separate message is generated to convey the alert notification comprising the information storage device parameter values from the information storage device to the processor.

3. The information handling system of claim 1, wherein the information storage device is configured to transmit the alert notification to the processor via the I/O bus.

4. The information handling system of claim 1, wherein the information storage device is configured to transmit the alert notification comprising the information storage device parameter values to the processor without requiring the processor to send a request for the information storage device parameters in response to the alert notification.

5. The information handling system of claim 1, wherein alert notification comprising the information storage device parameter values is included in a device-to-host serial advanced technology attachment (SATA) frame information structure (FIS).

6. The information handling system of claim 1, wherein the alert notification comprising the information storage device parameter values is included in a new device-to-host serial advanced technology attachment (SATA) frame information structure (FIS) distinct from an existing device-to-host SATA FIS.

7. The information handling system of claim 1, wherein the processor is a management controller.

8. A method comprising:

receiving, at an information storage device, a specification of reporting criteria for a plurality of information storage device parameters;

receiving a specification of logical relationships for the reporting criteria;

monitoring information storage device parameter values for the information storage device parameters;

comparing the information storage device parameter values to the reporting criteria to obtain indications of whether the reporting criteria have been satisfied;

applying the logical relationships to the indications; and

in response to the logical relationships applied to the indications yielding a first result, transmitting an alert notification including information storage device parameter values as an electromagnetic signal.

9. The method of claim 8 wherein, when traffic is present on the I/O bus, the alert notification comprising the information storage device parameter values is included as part of a return status being sent from the information storage device to the processor in response to a command issued by the processor to the information storage device, and, when traffic is not present on the I/O bus, a separate message is generated to convey the alert notification comprising the information storage device parameter values from the information storage device to the processor.

10. The method of claim 8 wherein the information storage device is configured to transmit the alert notification to the processor via the I/O bus.

11. The method of claim 8 wherein the information storage device is configured to transmit the alert notification comprising the information storage device parameter values to the processor without requiring the processor to send a request for the information storage device parameters in response to the alert notification.

12. The method of claim 8, wherein alert notification comprising the information storage device parameter values is included in a device-to-host serial advanced technology attachment (SATA) frame information structure (FIS).

13. The method of claim 8, wherein the alert notification comprising the information storage device parameter values is included in a new device-to-host serial advanced technology attachment (SATA) frame information structure (FIS) distinct from an existing device-to-host SATA FIS.

14. The method of claim 8, wherein the processor is a management controller.

15. A method comprising:

receiving, at an information storage device, reporting criteria for a plurality of information storage device parameters and logical relationships for the reporting criteria;

monitoring information storage device parameter values for the information storage device parameters; and

in response to the logical relationships applied to comparisons of the information storage device parameter values to the reporting criteria, transmitting an alert notification including information storage device parameter values as an electromagnetic signal in the form of a single contiguous message for which a corresponding command to send the single contiguous message has not been received by the information storage device.

16. The method of claim 15, wherein, when traffic is present on an I/O bus coupled to the information storage device, the alert notification comprising the information storage device parameter values is included as part of a return status being sent from the information storage device to the processor in response to a command issued by the processor to the information storage device, and, when traffic is not present on the I/O bus, a separate message is generated to convey the alert notification comprising the information storage device parameter values from the information storage device to the processor.

17. The method of claim 15, wherein the information storage device is configured to transmit the alert notification comprising the information storage device parameter values to a processor without requiring the processor to send a request for the information storage device parameters in response to the alert notification.

18. The method of claim 15, wherein the transmitting the alert notification as the electromagnetic signal occurs asynchronously with respect to commands received by the information storage device over the I/O bus.

19. The method of claim 15, wherein alert notification comprising the information storage device parameter values is included in a device-to-host serial advanced technology attachment (SATA) frame information structure (FIS).

20. The method of claim 15, wherein the alert notification comprising the information storage device parameter values is included in a new device-to-host serial advanced technology attachment (SATA) frame information structure (FIS) distinct from an existing register device-to-host SATA FIS.
