RAID 1 (Disk Mirroring)

Introduction

RAID 1 (Disk Mirroring) is a fault tolerance configuration. In this RAID data is coped simultaneously from one disk to another disk creating a replica of the disk. The advantage of this is if one disk fries we can use other drive and keep the system work. the main disadvantage of this is it create slight drag of performance.We can implement this by software RAID and hardware RAID.Minimum two disks required with software RAID we can use two use two volumes in single disk to mirror. This cuts the capacity by half .

Lets see how to create RAID 1 (Disk Mirroring)
