Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication networks with different protocols are used to connect controllers and processing devices, then communication flexibility and device compatibility are improved, but system complexity increases
Solution Approach 1:
The system is divided into two distinct communication networks: a first communication network connecting instruction processing devices to controllers, and a second communication network (ring network) connecting processing devices to each other. This segmentation allows each network to use optimized protocols for its specific purpose, improving overall compatibility while managing complexity through clear separation of concerns.
Solution Approach 2:
Controllers act as intermediaries between the first communication network and processing devices, while the ring network structure serves as an intermediary communication path between processing devices. This intermediary approach enables different communication protocols to coexist without direct interference, maintaining compatibility across diverse devices.
2Reliability
If a ring network topology is used for the second communication network, then communication reliability and fault tolerance are improved, but network complexity increases
Solution Approach 1:
The ring network implements dynamic path selection and automatic failure detection mechanisms. When a link failure is detected, the network dynamically reroutes communications through alternative paths in the ring, maintaining reliability without requiring complex manual intervention or static configuration for every possible failure scenario.
3Productivity
If hierarchical management structure is implemented with instruction processing devices and controllers, then operational efficiency is improved, but management complexity increases
Solution Approach 1:
The management hierarchy is segmented into distinct levels: instruction processing devices that issue high-level commands, controllers that translate these into device-specific instructions, and processing devices that execute operations. This segmentation improves operational efficiency by allowing each layer to focus on its specific function while reducing management complexity through clear division of responsibilities.

AI summary
The present disclosure describes a data center system including an instruction processing device for a chassis including one or more boards, a board including a set of cards, a card including a computing node or a processing device and a controller. The controller can receive an instruction from the instruction processing device through a first communication network between the controller and the instruction processing device. Based on the instruction, the processing device of the card can generate an operation result and provide the operation result to another device of the board through a second communication network different from the first communication network. The second communication network can have a ring topology or other topology. The instruction processing device can further operate a hierarchical manager to create a network manager to manage the operations of the board.
