摘要
随着远程容灾、内容分发、数据网格等不断发展,要求数据存储的范围从局域网拓展到广域网。本文提出了基于iSCSI协议的IP存储广域网系统模型,并利用一种新的可用性度量标准—任务完成概率,分析了IP存储广域网的可用性。分析结果表明:当任务数量达到百万时,系统完成概率在99.7％左右。
With the increasingly development of remote disaster-tolerance, content distribution and data grid, there is a crucial need to extend the scope of data storage from LAN to WAN. The IP-SWAN system model based on iSCSI protocol is proposed in the paper. The availability analysis of IP-SWAN is made with a novel metric for availability： the probability of task completion. The analysis results show that the probability of the whole system task completion is approximately 99.7% when the number of tasks reaches a million.
