中文摘要：
提出和实现了一种在IP下融合NAS（附网存储）、SAN（存储区域网）和对象存储技术的高可用海量网络存储系统（MNSS，mass network storage system）。在MNSS中通过统一多协议文件系统，实现了NAS设备、SAN设备和对象存储设备在IP上的融合，满足了应用开放性、高扩展和海量存储的需求；通过iSCSI软件模块，MNSS对存储资源提供统一的管理和优化，同时提供文件I／O和块I／O服务，使MNSS同时具有NAS和SAN的优点；通过自主存储代理模块，MNSS能同时提供服务器通道和附网高速通道，改善了系统的I／O性能，减少了服务器瓶颈；通过高可用系统设计，MNSS能为数据和应用提供更高的可用性，满足了企业高可用的存储需求。实验结果显示，MNSS有超高速的文件I／O和块I／O响应速度，能为网络提供高性能、高扩展性的对象存储设备，高可用性、高性，价比的海量存储系统。
英文摘要：
An IP-based high-available mass network storage system （MNSS） was introduced, featured by the following advantages： firstly, it integrates multi-NAS and SAN with OSD through a unified multi-protocol f＇de system （UMPFS）, with greater capacity and better scalability than each of them; secondly, it simultaneously serves both the file I/O and the block I/O by an iSCSI module, with all the advantages of a NAS and a SAN; thirdly, with an autonomic storage agency （ASA）, the MNSS provide two kinds of data channels, i.e., a server channel and a high-speed network-attached channel, by which the I/O performance is improved and server bottlenecks are reduced; fourthly, high availability is attained by way of a high-available file system. In addition, in the experiment concerned, the MNSS has proved to be a network storage system with great capacity producing an ultra-high-throughput for both the file I/O and the block I/O, characterized by better performance, scalability, availability and cost performance,etc, when compared with those systems already on the market.
