| 随着Internet的发展,应用的数据存储量与其增长速度都相当高,同时数据具有结构化特点,当前的(分布式)文件系统与数据库系统都无法较好地满足这一类需求.提出了一种网络附属对象存储设备模型,利用自身处理器的能力,提供结构化数据的存储/检索接口,消除了传统存储系统的服务器瓶颈问题.同时提出了基于该对象设备的集群存储体系--OStorage.它利用集群网络方式,实现了数据/元数据统一存储与查询式数据访问机制.其在系统的可扩展性、可用性与对结构化数据的支持上,均较符合当前存储应用的特点.实现了该体系的原型系统.测试结果表明,其吞吐率随规模的扩大呈线性增长. |

| Abstract: |
| With the ever-increasing development of Internet, today抯 data-centric applications require storage platforms not only to possess some properties including high capacity and high scalability, but also to support structured data directly, which is beyond the abilities of current file systems and DBMS. In this paper, a model of network-attached object-based storage devices is presented. It provides storage and index interfaces for structured data employing the power of embedded processors, which eliminates the bottleneck of conventional storage systems. Then the architecture of cluster storage based on the model OStorage is proposed. It introduces the uniform storage of data and meta-data as well as query-locating mechanism to adapt storage hierarchies to structured data. These two methods improve the scalability and availability of the storage system. The prototype of Ostorage is implemented. The experimental results show that the throughput of it increases with the system scale linearly. |
