基于负载均衡的阵列存储策略设计与实现
Design and Implementation of a RAID Storage Strategy Based on Load Balancing
摘要
Abstract
According to the challenges of data storage in the aerospace field,an FPGA-based serial ATA(SA-TA)controller is designed,focusing on solid-state drive(SSD)media.The designed controller achieves an aver-age read/write speed of 500 MB/s for a single hard drive and integrates the ATA command set to enable self-monitoring,analysis,and repoting technology(S.M.A.R.T.)functionality for monitoring the health status of SATA hard drives.To further meet the demands for high-capacity,high-throughput data storage tasks,a multi-SSD array system is implemented based on the single-drive controller,a load-balancing-based array storage strategy is innovatively proposed by dynamically monitoring drive health and adaptively adjusting data alloca-tion,which significantly reduces the performance degradation impact of individual drives in space environments on the overall array system.Experiments are conducted using the domestically developed V7-690T FPGA for validation.The results show that when a single drive experiences performance degrades by 65％,the proposed load-balanced four-drive array system achieves over 50％higher performance compared to traditional RAID0.This solution significantly enhances the efficiency of storage systems in scenarios where individual drives suffer performance degradation,making it higly valuable for practical applications.关键词
