摘要
Swift是开源云计算平台OpenStack中云存储服务组件,为平台提供廉价、可靠、安全的云存储服务。针对Swift没有充分利用存储系统的备份数据来实现并行读取操作及负载均衡的这一问题,提出了基于I/O负载均衡的并发读策略。实验结果表明,该策略不仅能够充分利用备份数据来达到存储设备读操作的负载均衡,而且能够实现数据的并行读取,提高平台整体读性能。
Swift is the opefl source cloud computing platform OpenStack cloud storage service component, as a platform to pro- vide cheap, reliable and secure cloud storage service. Backup data for Swift did riot make full use of the storage system to achieve parallel read operation and load balancing problems, based on the I/O load balancing concurrent reading strategies. The experi- mental results show that the strategy is not only take full advantage of backup data storage devices read operation to achieve load balancing, but also achieve parallel data read and improve the platform overall reading performance.
