摘　　要：文章研究了云计算环境中公民信息管理的数据存储可靠性技术,提出了一种新型的可靠性保障模型,并通过性能测试验证其有效性。实验采用KVM虚拟化平台,模拟分布式存储、RAID和纠删码三种存储技术,评估它们在不同故障和负载条件下的数据恢复时间、存储损失、系统吞吐量等性能。测试结果表明,RAID技术在数据恢复和吞吐量方面具有最佳表现,特别是在存储损失和恢复比例上;分布式存储在低负载时吞吐量较高,但随着负载增加,恢复时间和吞吐量下降;纠删码则在高故障率下能恢复更多数据,但恢复时间较长,吞吐量较低。This article studies the reliability technology of data storage in cloud computing environments with a focus on citizen information management,proposes a new reliability assurance model,and verifies its effectiveness through performance testing.The experiment utilized a KVM virtualization platform to simulate three storage technologies:distributed storage,RAID,and erasure coding,evaluating their performance in data recovery time,storage loss,system throughput,among other metrics,under various fault and load conditions.Test results indicate that RAID technology excels in data recovery and throughput,particularly in terms of storage loss and recovery ratios.Distributed storage exhibits higher throughput at low loads,but both recovery time and throughput decline as load increases.Erasure coding recovers more data at high failure rates,albeit with longer recovery times and lower throughput.
