基于iSCSI的软件RAID的小型企业网络解决方案

Network Solution of Small Enterprise Based on Software RAID of iSCSI

iSCSI作为SCSI的网络解决方案,通常利用硬件RAID卡将多块磁盘按不同的方式组合成一个磁盘组,提供数据冗余的存储方案,现广泛用于大型企业和高等院校等的信息系统,但此方案的成本较高.本文使用iSCSI的软件RAID,将几个独立计算机通过局域网连接,充分利用网络和磁盘资源,组成一个GB级的分布式存储,实现低成本分布式存储解决方案,对此系统进行了性能测试,并对此方案应用于小型企业的可行性进行了分析.分析表明,此方案完全可用于小型企业,同时可推广到中小学校和家庭用户.

As the network solution of SCSI, iSGSI usually makes up a disk organization with several dlsl^s in different ways using hardware RAID cards and provides memory solution with data redundancy. It is generally applied in information systems of large-scale company and institutions of higher learning at present, but the cost is relatively high. The software RAID used by iSCSI in this article connects several independent computer with LAN and adequately makes use of network and disk resources. It makes up a distributive storage of GB level to realize low-cost distributive memory solution. It carries on a capability testing on this system and analyzes the feasibility of applying this scheme to small enterprise. The analysis indicates that the scheme is absolutely capable of applying in small enterprise, at the same time, it may extends to primary schools, high schools and domestic users.
