Engineering Contradiction Analysis
1Productivity
If CPU compression algorithms are used, then compression functionality is provided, but CPU resource occupation is high
Solution Approach 1:
The patent replaces software-based CPU compression algorithms with hardware-based PCIe compression accelerator cards. The compression function is migrated from the CPU's software execution environment to dedicated hardware acceleration cards, achieving hardware acceleration for data compression and reducing CPU resource occupation while maintaining compression performance.
Solution Approach 2:
The patent introduces a PCIe compression accelerator card as an intermediary device between the CPU and storage devices. This intermediate hardware component handles compression and decompression operations, freeing the CPU from these computationally intensive tasks while providing efficient data processing capabilities.
2Use of energy by moving object
If PCIe compression accelerator card is used, then CPU resource occupation is reduced, but supporting software development complexity increases
Solution Approach 1:
The patent makes the PCIe compression accelerator card compatible with multiple operating systems (Windows, Linux, Unix) and storage protocols (NVMe, SATA, SAS) through universal driver interfaces. This multi-functionality allows the hardware compression card to work across different platforms without requiring extensive platform-specific software development, reducing the complexity of supporting software.
Solution Approach 2:
The patent simulates the compression accelerator card as a virtual hard disk device, copying the familiar hard disk access interface and protocols. This simulation approach allows existing hard disk access software to work with the compression card without modification, eliminating the need for extensive supporting software development while providing hardware acceleration capabilities.
3Productivity
If hardware compression card is adopted, then compression performance is improved, but enterprise equipment cost increases
Solution Approach 1:
The patent combines multiple functions (compression, decompression, storage simulation, multiple protocol support) into a single PCIe compression accelerator card. This consolidation reduces the need for separate hardware components and software solutions, providing high compression performance while controlling overall equipment costs through functional integration.
