The level of RAID 5 is called disk striping with parity. If one of the drives in the set fails, Parity is used to restore data from the other drives.
How do you calculate data parity?
The calculation of the parity information can be done using a XOR operation between the data on the other 2 disks. Our third disk would hold the parity information.
What is parity in RAID?
Parity computations are used in RAID drive array for fault tolerance by calculating the data in two drives and storing the results on a third drive.
What does a parity bit in RAID 5 handle?
A single data bit is added to the end of a data block to make sure the number of bits in the message is even or odd.
How is RAID 5 calculated?
To get an idea of the usable amount that will be available to hosts, take the amount of capacity on the disk drive and reduce it by 15%.
