定义
定义什么是磁盘组和虚拟磁盘非常重要。
磁盘组
被逻辑分组并分配了 RAID 级别的一组物理磁盘。每个磁盘组均提供了创建一个或多个虚拟磁盘所需的整体容量。
虚拟磁盘
为使主机可以访问存储阵列上的存储数据而创建的逻辑组件。虚拟磁盘从磁盘组上可用的容量创建,并显示为一个逻辑组件(即使该虚拟磁盘是从多个物理磁盘创建的也是如此)。
在PowerEdge控制器(PERC)中,可以创建虚拟磁盘。备份该虚拟磁盘的步骤有哪些?
示例:
Raid-5 模式的 1 个虚拟磁盘由 3 个 600GB 的磁盘组成。
提醒:
在操作系统层面下,此虚拟磁盘的最大容量将为 1200GB。
这不可能直接在虚拟磁盘级别备份。备份数据意味着在
操作系统层面
进行备份。该虚拟磁盘用一个分区表示,此分区可以使用备份工具保存。
戴尔提供了许多根据需要备份数据的解决方案。可以在文件级别到裸机还原级别执行备份。
在本示例中,假设Windows服务器正在PowerEdge上运行,您可以使用Windows服务器备份工具创建映像备份。如果需要还原数据,您可在虚拟磁盘上还原整个映像。
