Device management method, device, and device management controller
First Claim
1. A device management method, comprising:
- sending, by a baseboard management controller (BMC) in a non-volatile memory express (NVMe) system, an instruction message to instruct multiple NVMe devices in the system to detect device management information, wherein the device management information comprises at least two pieces of the following information;
an in-position status, a temperature, a power status, a working status, storage space, and software configuration information of the device;
comparing, by each NVMe device, each current piece of device management information with each piece of device management information in the previous query period;
determining, by each NVMe device, whether current device management information is changed;
generating, by an NVMe device whose current device management information is changed, a feedback message;
receiving, by the BMC, the feedback message from the NVMe device whose current device management information is changed, wherein the feedback message indicates at least one piece of changed device management information, wherein the feedback message indicates at least one piece of changed device management information using a number and a value, and wherein each number corresponds to each type of the device management information; and
managing, by the BMC, the NVMe device whose current device management information is changed according to the at least one piece of changed device management information.

Abstract
A device management method, a device, and a device management controller are provided. The method includes receiving, by a device, a first instruction message sent by a device management controller, determining, by the device according to the first instruction message, a status of current device management information compared with device management information in a previous query period, generating a first feedback message, where the first feedback message indicates the status of the device management information, and sending, by the device, the first feedback message to the device management controller such that the device management controller manages the device according to the first feedback message. The device feeds back to the device management controller only the status of the current device management information compared with the device management information in the previous query period, effectively reducing a transmission amount of device management information.

4. A system, comprising:
-
multiple non-volatile memory express (NVME) devices; and a baseboard management controller (BMC) configured to send an instruction message to an NVMe system to instruct the multiple NVMe devices in the system to detect device management information, wherein the device management information comprises at least two pieces of the following information;
an in-position status, a temperature, a power status, a working status, storage space, and software configuration information of the device,wherein each of the multiple NVMe devices is configured to compare each current piece of device management information with each piece of device management information in the previous query period, and determine whether current device management information is changed, wherein an NVMe device whose current device management information is changed is configured to generate a feedback message, wherein the BMC is further configured to receive the feedback message from the NVMe device whose current device management information is changed, wherein the feedback message indicates at least one piece of changed device management information, wherein the feedback message indicates at least one piece of changed device management information using a number and a value, wherein each number corresponds to each type of the device management information, and wherein the BMC manages the NVMe device whose current device management information is changed according to the at least one piece of changed device management information. - View Dependent Claims (5, 6)
