Description

System and method for accessing MCTP (multimedia broadcast multicast service) equipment through SMASH (simple multimedia application service) interface

Technical Field

The invention relates to the technical field of Server Management, in particular to a system and a method for accessing MCTP (Management Component Transport Protocol) equipment through an SMASH (System Management Architecture for Server Hardware System Management) interface.

Background

Servers, also known as servers, are devices that provide computing services. Devices or sensors on the server are managed by BMC (Baseboard Management Controller) or NM (Network Management)/ME (Management Engine) on the server. Typically BMCs will access managed devices via I2C or PCIe, which is standardized by some on-board protocols such as MCTP, PMBus, NCSI, etc. At the same time, the BMC provides interfaces for external access standardized by external protocols, such as SMASH, Redfish, IPMI, etc. These standards are generally defined by the international organization for standardization DMTF (Distributed Management Task Force).

Among them, the MCTP protocol standard is a core standard that is updated frequently in recent years in the art and solves a significant problem in server monitoring. NCSI support issues such as add-in network cards, asset information of devices, sensor monitoring issues, upgrade issues of smart devices, etc. These problems are well solved in the MCTP protocol.

The SMASH protocol standard is used to manage servers through command lines. However, the SMASH protocol standard does not define the method of using MCTP, and if an external user wants to enjoy the benefits of the MCTP protocol, it needs to wait for the BMC manufacturer to complete a lot of updates and adaptations to enjoy the benefits of the MCTP protocol. Meanwhile, since the MCTP protocol is still under continuous update, even if the BMC manufacturer provides the aforementioned update, it has to wait for the next update again to use some new functions of the MCTP device, which reduces the efficiency of using the MCTP device.

Therefore, how to provide a way for a user to conveniently use an MCTP device, especially new functions based on the upgrade of the MCTP device, without waiting for more updates of the BMC firmware, is a problem that needs to be solved by those skilled in the art.
