Out-of-band BMC Storage Monitoring Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices face inefficiencies in transmitting hardware information, leading to increased bandwidth consumption and decreased user data transmission speed, particularly when using in-band communication for exchanging temperature, voltage, and humidity data.
Innovation Solution
The implementation of a method where a host device with a baseboard management controller and a storage device with a microcontroller use direct communication interfaces for out-of-band communication to monitor hardware components, detect abnormal situations, and provide warning messages to perform preventive actions, such as adjusting voltage levels or backing up data, thereby reducing bandwidth consumption and maintaining data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If in-band communication is used to transmit hardware information between host device and storage device, then hardware information can be exchanged, but bandwidth consumption increases and user data transmission speed decreases
Solution Approach 1:
The patent segments communication into two separate channels: in-band communication for user data and out-of-band communication for hardware information. This segmentation allows hardware monitoring to occur independently without consuming the data transmission bandwidth, thus resolving the contradiction between transmitting hardware information and maintaining high user data transmission speed.
Solution Approach 2:
The patent introduces a baseboard management controller (BMC) as an intermediary device that handles hardware information transmission through out-of-band communication. The BMC acts as a mediator between the host device and storage device, enabling hardware monitoring without interfering with the primary data transmission path, thereby preserving bandwidth for user data.
2Reliability
If hardware information is transmitted through in-band communication, then monitoring capability is achieved, but bandwidth consumption increases
Solution Approach 1:
The patent divides the communication system into data communication (in-band) and management communication (out-of-band) segments. Hardware monitoring information is transmitted through the out-of-band segment, which does not compete with data transmission bandwidth, thus achieving reliable hardware monitoring without increasing overall bandwidth consumption.
Solution Approach 2:
The BMC serves as an intermediary that collects and transmits hardware information through a dedicated out-of-band channel. This intermediary approach enables comprehensive hardware monitoring while isolating it from the data transmission path, preventing bandwidth consumption conflicts and maintaining system reliability.
