BASEBOARD MANAGEMENT CONTROLLER (BMC) TO HOST COMMUNICATION THROUGH DEVICE INDEPENDENT UNIVERSAL SERIAL BUS (USB) INTERFACE

摘要

Aspects of the disclosure relate to systems and methods for performing communications between a management device and a host computer through a device independent universal serial bus (USB) interface. The system includes a management device communicatively connected to a computing device through a first communication link. In operation, the management device emulates a mass storage device to the computing device through the first communication link, and then identifies the emulated mass storage device as an unsupported mass storage device to the computing device, such that the emulated mass storage device is accessible by the computing device as a bulk-only device. Thus, Intelligent Platform Management Interface (IPMI) communications between the management device and the computing device may be performed using the bulk-only device mechanism.

主权项

1. A system, comprising:
a management device communicatively connected to a computing device through a first communication link, the management device comprising a processor and a storage device storing computer executable code, wherein the computer executable code, when executed at the processor, is configured to:
emulate the management device as a mass storage device to the computing device through the first communication link;identify the emulated mass storage device as an unsupported mass storage device to the computing device, such that the emulated mass storage device is accessible by the computing device as a bulk-only device; andin response to receiving a first message from the computing device directed toward the bulk-only device through the first communication link,
determine whether the first message is an Intelligent Platform Management Interface (IPMI) message intended for communication with the management device, or a non-IPMI message; andwhen the first message is the IPMI message, process the IPMI message.
