Mirroring of RAID 1
Basically, the RAID 1 Mirroring is implemented when some fault tolerance is desired. The ability of the required data in the array to survive the failure of a disc is mainly known as fault tolerance. Like every piece of data in a mirrored array is duplicated over two or more hard discs accordingly. That’s why, all of one’s crucial data would be kept on a mirrored array to access the required data from the other drive, even in the event that one of the hard drives may fail. The RAID 1 mirroring is available across all of ZNetLive’s dedicated servers as well.
Disk Mirroring (RAID 1)
RAID 1 stands for Redundant Array of Independent Disks 1. RAID 1, also known as disk mirroring, is the technique of storing a copy of the same data in another disk. Here, the data is not broken into blocks rather a duplicate copy of the data is stored in another disk. A minimum of 2 disks are required in RAID.
Supposing, we have some data namely, D1, D2, and D3. In RAID 1, along with these original data we store copies of these data in another disk. Below is a diagram justifying the above statement and thus explaining the concept of RAID 1.
