尽管有些人认为存储区域网络(SAN)与网络连接存储(NAS)体系的融合是一种硬性的组合,但这两种技术的融合正在积极发展。为了弄清两者之间的关系,让我们仔细分析一下这两种技术。大家普遍认为,IT 存储需求以一种跳跃式的速度增长。实际上,有报告显示 IT 存储能力现住正以每年52%的速度提高。要使存储能力跟上存储需求的步伐,意味着不仅要不断增加新的物理硬件,还要创建新的架构来管理这些硬件设施。在当前的 IT 预算已经被大幅削减的情况下,这种双重需求通常是很要命的。幸运的是,我们已经开始脱离直接连结存储(DAS)模式。这种昂贵的存储模式需要给每个单独的服务器增加硬盘,但 While some believe that the convergence of storage area networks (SANs) and network attached storage (NAS) systems is a hardcore combination, the convergence of both technologies is evolving. To understand the relationship between the two, let’s take a closer look at both techniques. It is generally believed that IT storage needs to grow at a leaping speed. In fact, there are reports that IT storage capacity is now increasing at a rate of 52% per annum. To keep pace with the storage needs of storage capacity, means not only to add new physical hardware, but also to create a new architecture to manage these hardware facilities. With the current IT budget has been drastically reduced, this dual need is often terrible. Fortunately, we have started to move away from DAS mode. This expensive storage model requires adding a hard drive to each individual server, though
