Abstract
With the rapid development of information technology and the explosive growth of data volume, storage systems are facing unprecedented challenges. Linux file systems, with their open source, flexibility and efficiency, show great potential in storage system optimization. This study aims to deeply explore the optimized application of the Linux file system in the storage system to improve the performance, reliability and scalability of the storage system. By analyzing the characteristics and limitations of the existing Linux file system, such as ext4 and XFS, and combining with the requirements of practical application scenarios, a comprehensive optimization scheme based on me tadata separation, intelligent cache mechanism and adaptive scheduling algorithm is proposed. Using the combination of theoretical analysis and experimental verification, the test platform was built to conduct a comprehensive comparative evaluation of the performance indicators before and after optimization. The results show that the proposed scheme effectively reduces the I / O latency, improves the throughput, and enhances the concurrent processing capability of the system. Especially in large-scale data read and write scenarios, the optimized file system shows better stability and response speed.
