Dynamic Topology Discovery for Multi-Protocol Peripheral Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing systems face challenges in efficiently supporting multiple peripheral communication protocols, particularly in datacenter environments where frequent upgrades are necessary due to increasing demand for data storage and low latency data maintenance. This leads to costly motherboard upgrades and temporary reductions in computing throughput during server downtimes.
Innovation Solution
The implementation of a computing system with multiple servers connected via connectors that support multiple communication protocols, allowing for flexible configuration and automatic protocol matching. A processor executes the topology manager to determine the communication protocol of attached peripheral devices and configure the connectors accordingly, ensuring seamless data transfer and minimizing configuration errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If motherboard upgrades are performed to support new communication protocols, then protocol compatibility is improved, but system cost increases and computing throughput decreases during upgrade downtime
Solution Approach 1:
The patent segments the protocol support functionality from the motherboard hardware into a separate software layer (topology manager and protocol detection module). This allows protocol compatibility to be upgraded independently via software updates rather than requiring physical motherboard replacement, thus maintaining computing throughput while improving adaptability to new protocols
Solution Approach 2:
The patent implements universal connector designs that can physically accommodate multiple peripheral device types (SAS, SATA, NVLink, etc.). The topology manager software then dynamically detects and configures the appropriate protocol for each connector, enabling a single motherboard to support multiple communication protocols simultaneously without hardware upgrades
2Adaptability or versatility
If multiple communication protocols are supported through hardware upgrades, then protocol versatility is improved, but device complexity increases
Solution Approach 1:
The patent extracts the protocol management complexity from the hardware layer and relocates it to the software layer. The topology manager and protocol detection modules handle protocol identification, configuration, and compatibility management, simplifying the motherboard hardware to universal connectors while maintaining multi-protocol support through software intelligence
Solution Approach 2:
The patent introduces the topology manager as an intermediary software layer between the hardware connectors and peripheral devices. This mediator automatically detects device types, determines appropriate protocols, and configures connectors accordingly, eliminating the need for complex hardware switching mechanisms while supporting multiple protocols
3Ease of operation
If protocol detection and configuration is automated, then ease of operation is improved, but software complexity increases
Solution Approach 1:
The patent implements self-service automation where the topology manager autonomously performs protocol detection, device identification, and connector configuration without user intervention. The system automatically queries device capabilities, matches compatible protocols, and configures connectors, providing ease of operation while consolidating software complexity into a dedicated management module
Data Source
AI summary
An apparatus and method for efficiently supporting multiple peripheral communication protocols in a computing system. A computing system includes multiple servers with one or more of the servers using multiple connectors for connecting to multiple peripheral devices such as data storage devices. At least one of the connectors is able to support multiple communication protocols, rather than a single communication protocol. A processor of the server determines a peripheral device has been attached to a connector that supports multiple communication protocols, and the processor determines whether one of the multiple communication protocols supported by the particular connector matches the attached peripheral device's communication protocol. If so, the processor configures the connector with the matching communication protocol. Otherwise, the processor generates an indication that specifies that there is no match.
