摘要
存储系统的服务质量(QoS)保证对于满足上层应用的需求至关重要。基于对象存储(OBS)使用支持丰富语义的对象级接口,能够更好地实现QoS保证。在研究了基于对象存储系统中QoS交互机制的基础上,提出了一个基于对象存储设备(OSD)的多维QoS框架,设计并实现了一个应用于OSD的多维QoS算法。实验显示,该框架和算法能有效满足多个客户端的不同维度QoS要求。
Quality of service (QoS) is an essential issue of storage systems. Using object-level interface with rich semantic support, object-based storage (OBS) provides convenience to guarantee QoS. After studying QoS communication mechanism in OBS, an object-based storage device (OSD) framework with multidimensional QoS support is proposed. Then a multidimensional QoS algorithm for OSD is designed and implemented. Experiment results shows that the framework and algorithm can successfully fulfill multidimensional QoS requirements of different clients.
