摘　　要：云存储作为下一代数据存储主要模式受到广泛关注。服务质量成为目前云存储研究中需要解决的关键问题。主要从服务模式的云存储形态出发,研究了该形态下涉及的若干关键技术,包括云存储SLA协商技术、云存储中数据安全保证技术、云存储资源管理技术等。综述了各项关键技术当前的研究现状,分析并指出了现有技术存在的问题,展望了未来的研究方向,提出了一种QoS感知的云存储服务模型。As one of the main next-generation storage patterns, cloud storage tectmologles have been widely studied and applied, and QoS guarantee issue has become the key problem to be resolved at present. According to the service patterns perspective, the major technologies about QoS guarantee for cloud storage were mainly summaried and discussed, including SLA negotiation, data storage security and resource management, the limitation existed in correlative researches were analyzed and fingered out, the future research directions were prospected, and finally a novel QoS-aware service model for cloud storage was proposed.
