Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 8 lanes of PCIe signals are transferred to two identical SSD cards, then data transfer capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the 8-lane PCIe signal transfer into two separate 4-lane transfers, with each SSD card receiving 4 lanes of PCIe signals. This segmentation allows the system to achieve high data transfer capability (8 lanes total) while reducing the complexity at each individual SSD card interface to 4 lanes, making the solution more manageable and compliant with VPX standards.
Solution Approach 2:
The patent introduces a switch as an intermediary component that receives 8 lanes of PCIe signals from a host device and distributes them to two SSD cards. This intermediary switch manages the signal routing and distribution, enabling the system to achieve high data transfer capability while the switch itself handles the complexity of signal management and distribution.
2Speed
If multiple PCIe lanes are used for data transfer, then data transfer speed is improved, but signal management complexity increases
Solution Approach 1:
The patent segments the 8-lane PCIe interface into two separate 4-lane interfaces, one for each SSD card. This segmentation maintains high data transfer speed (8 lanes total) while reducing the signal management complexity at each individual card to 4 lanes, making it more compliant with VPX standards and easier to manage.
Solution Approach 2:
The switch acts as an intermediary that manages the 8 lanes of PCIe signals, receiving them from the host device and distributing them to two SSD cards. This intermediary handles the complex signal management tasks, enabling high-speed data transfer while the switch manages the routing and distribution of signals.
3Adaptability or versatility
If VPX standards are complied with, then system compatibility is improved, but data transfer configuration complexity increases
Solution Approach 1:
The patent segments the data transfer configuration into two separate 4-lane PCIe interfaces, one for each SSD card. This segmentation simplifies the configuration process while maintaining compliance with VPX standards, as each card can be configured independently with standard 4-lane interfaces rather than requiring complex 8-lane configurations.
Solution Approach 2:
The switch serves as an intermediary that handles the complex data transfer configuration, enabling the system to comply with VPX standards. The switch manages the signal routing and distribution, simplifying the configuration process while maintaining system compatibility and adherence to VPX requirements.
