问题描述
我对RAID1和RAID5硬件解决方案有一些疑问.例如，我在Windows Server 2003中将RAID1实施为磁盘镜像.如何在实际环境中测试该磁盘镜像的作用?这是否意味着如果一个硬盘驱动器发生故障，系统将继续在镜像驱动器上运行?或者，当一个硬盘驱动器发生故障时，系统将发生故障，但是一个硬盘驱动器可以将系统重新引导至镜像驱动器吗?
同样，如果我使用3个磁盘实现RAID5，它的实际作用是什么?它是否支持故障转移，数据冗余或两者兼而有之? RAID5如何实现它?
Hi,
I have got some questions about RAID1 and RAID5 hardware solutions. For example, I implemented RAID1 as disk mirroring in Windows Server 2003. How do I test this disk mirroring in action in the real world? Does it mean if one hard drive has failed, the system will continue to operate on the mirrored drive? Or when one hard drive has failed, the system will fail but one can reboot the system to the mirrored drive?
Similarly, if I implement a RAID5 using 3 disks, what does it really do? Does it support failover, data redundancy or both? How does RAID5 achieve it?
