Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a detailed identification solution with matrix sorting is used to cover all possible configurations, then configuration identification accuracy is improved, but device complexity and implementation cost increase significantly
Solution Approach 1:
The patent implements a universal identification method where the BIOS reads peripheral ID signals directly from the MCIO connector to determine PCIE bandwidth allocation. This single universal approach handles all configuration scenarios (x4, x8, x16 bandwidths and mixed hard disk types) without requiring separate identification matrices for each configuration, thereby reducing system complexity while maintaining identification accuracy.
Solution Approach 2:
The patent extracts the essential identification information by reading only the peripheral ID signals from the MCIO connector, which directly indicate the PCIE bandwidth configuration. This extraction approach eliminates the need for complex matrix sorting and comprehensive configuration checking, achieving accurate identification with minimal signaling overhead.
2Adaptability or versatility
If PCIE bandwidth allocation is dynamically adjusted for mixed hard disk configurations, then system adaptability is improved, but configuration identification feasibility deteriorates due to hundreds of possible combinations
Solution Approach 1:
The patent changes the identification parameter from complex configuration matrices to simple peripheral ID signal levels on the MCIO connector. By monitoring the voltage levels of these signals, the system can directly determine the required PCIE bandwidth allocation for any hard disk configuration, enabling dynamic adaptability without encountering the combinatorial explosion of identification scenarios.
3Ease of manufacture
If traditional configuration identification methods are used, then implementation cost is reduced, but configuration identification efficiency and feasibility decrease for mixed hard disk scenarios
Solution Approach 1:
The patent enables the system to self-identify its configuration by automatically reading the peripheral ID signals from the MCIO connector during BIOS initialization. This self-service approach eliminates the need for external configuration input or complex identification routines, achieving both low implementation cost and high identification efficiency for mixed hard disk scenarios.

AI summary
Disclosed are a method and apparatus for identifying peripheral configuration of server, a method and apparatus for laying out peripheral silkscreen, and a server. The method includes: determining a PCIE external interface of each central processing unit on the basis of configuration requirement information of a server to be identified; determining, in sequence according to a level state of each peripheral ID signal transmitted by each PCIE external interface, a peripheral type that is capable of being configured for a peripheral bandwidth corresponding to the peripheral ID signal, allocating corresponding serial numbers to peripherals of different peripheral types, generating a peripheral silkscreen including all peripheral sequences managed by the server to be identified; sending the peripheral silkscreen to a basic input output system and/or a baseboard management controller, and allowing the basic input output system and/or the baseboard management controller to unify respective default silkscreen into the peripheral silkscreen.
