Host Adapter Card Dual-Protocol Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network communication specifications like Infiniband and Ethernet require different mechanical and electrical connectors and cables, limiting compatibility and flexibility in high-performance computing environments.
Innovation Solution
A dual-protocol networking system with a host adapter card and an alternative network compatibility device that automatically detects connections to either Infiniband or Ethernet, using a single ASIC with control logic to select the appropriate protocol based on the number of channels present, without converting data protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different mechanical and electrical connectors and cables are used for Infiniband and Ethernet, then protocol-specific performance is optimized, but compatibility and flexibility are reduced
Solution Approach 1:
The host adapter card is designed with a universal connector that can interface with both Infiniband and Ethernet networks. The card includes multiple transceiver pairs that can be selectively activated based on the detected network type, allowing a single device to perform multiple functions and connect to different network protocols using the same physical interface.
2Adaptability or versatility
If multiple adapter cards are used to support both Infiniband and Ethernet, then protocol compatibility is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the functionality of separate Infiniband and Ethernet adapter cards into a single unified host adapter card. The card integrates multiple transceiver pairs and control logic that can detect the network type and automatically configure itself to operate on either Infiniband or Ethernet networks, eliminating the need for multiple separate cards.
Solution Approach 2:
The single host adapter card is designed to perform multiple functions by supporting both Infiniband and Ethernet protocols through its universal connector and configurable transceivers, allowing one device to replace what would traditionally require multiple specialized cards.
3Ease of operation
If automatic protocol detection is implemented, then ease of operation is improved, but control logic complexity increases
Solution Approach 1:
The host adapter card incorporates automatic self-detection capability that allows it to identify whether it is connected to an Infiniband or Ethernet network without user intervention. The control logic automatically configures the appropriate transceivers and protocol settings based on the detected network type, making the system self-configuring and easy to operate.

AI summary
A networking system includes a host adapter card including a card connector having four transceiver pairs and a mechanical connector configuration, and a controller having control logic for detecting whether a single-channel connection or a four-channel connection is made to the card connector. The controller further includes control logic for communicating over a network using a default, four-channel-protocol in response to detecting the four-channel connection or using an alternative, single-channel-protocol in response to detecting the single-channel connection. The system further includes an alternative-network compatibility device including a first connector configured for releasably mating with the card connector and a second connector having a different mechanical connector configuration than the card connector. The alternative-network compatibility device includes a transceiver lane from the first connector end to the second connector end, which transceiver lane is placed in connection with one of the four transceiver pairs when mated with the card connector.
