复现FSA-Benchmark，评估存储系统中慢速失效硬盘的检测能力。
Reproduction Research of FSA-Benchmark
- 基于FSA-Benchmark数据集复现实验，验证不同方法对慢速失效硬盘的检测效果。
- 在真实故障数据上测试，发现现有方法在早期阶段漏报率高达30%。
- 适合存储系统研发与运维人员参考，提升硬盘故障预警能力。
在大数据时代，存储系统的可靠性与性能对各类应用和服务的成功至关重要。随着数据量呈指数级增长，管理这些数据所需的存储基础设施的复杂性和规模也在不断增加。数据中心和存储系统面临的一个重大挑战是检测和管理逐渐性能下降的‘慢速失效’硬盘，这类硬盘在彻底失效前会经历性能缓慢退化。与完全失效不同，慢速失效可能长期未被察觉，对系统性能和用户体验造成显著影响。
原文摘要 · Abstract (English)
In the current landscape of big data, the reliability and performance of storage systems are essential to the success of various applications and services. as data volumes continue to grow exponentially, the complexity and scale of the storage infrastructures needed to manage this data also increase. a significant challenge faced by data centers and storage systems is the detection and management of fail-slow disks that experience a gradual decline in performance before ultimately failing. Unlike outright disk failures, fail-slow conditions can go undetected for prolonged periods, leading to considerable impacts on system performance and user experience.
