在网上看到很多关于虚拟化的东西,自己也关注过很长时间,居然没有查到中文的定义,下面的英文部分是从中搜到的,中文部分是自己的简单总结。 Virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. 依据个人的理解,虚拟化实质是将繁杂的物理操作转变为较为简单的逻辑操作。 Storage virtualization is commonly used in a storage area network (
). The management of storage devices can be tedious and time-consuming. SAN并不是使用虚拟化的标准,真正的标准是存储设备的数量与物理管理的复杂程度;节省了管理时间,提高了管理效能是实施虚拟化的目的。 Storage virtualization helps the storage administrator perform the tasks of backup, archiving, and recovery more easily, and in less time, by disguising the actual complexity of the SAN. 存储虚拟化是否成功应该从管理的灵活性,全面性,成熟性来考虑。 再来点感想
