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。
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 file 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.
