SAS1068E RAID卡创建RAID1 磁盘阵列

Posted by wxianfeng Tue, 19 Feb 2013 17:15:00 GMT

为生产服务器搭建RAID1磁盘阵列,一共四块 1T 硬盘, 其中两块做RAID 1, 作为数据盘, 一块为操作系统盘, 一块为 备份盘.

什么是 RAID1 ?

RAID 1 是两块物理硬盘作为一个逻辑盘, 可以有效的备份, 两块盘的数据一摸一样, 可以提高读的性能, 写性能变化不大.

搭建过程:

1, 开机按 ctrl + c 进入创建界面, 回车进入 adater properties

2, 选择 RAID Properties

3, 选择 create IM volume 创建 RAID 1

4, 选择两块硬盘作为 RAID 1盘, 按空格 选中, 按 c 创建

5, 保存被退出

6, 最后查看到RAID 1 列表

下图的 sdc 就是 RAID 1的逻辑盘

操作系统安装在sda 盘

另外的 sdb 盘就是备份盘了.

关于 RAID 网上看到的很形象的图, 呵呵.
