Q

What does RAID 0 do?

A

Takes the contents of files and spreads them in roughly even parts across all drives in the RAID array.

20
Q

What does RAID 10 do?

A

Requires four hard drives, two hard drives for the disk mirror and then two more disks to strip the mirrored disks.

21
Q

What does RAID 1 do?

A

Writes identical data to two or more hard drives

22
Q

What does RAID 5 do?

A

Uses disk striping across at least three drives and includes parity data.

23
Q

What are the steps to replacing a failed RAID drive?

A
  1. Create a backup of the data.
  2. Remove the failed drive.
  3. Install a new drive of equal or greater capacity in place of the failed drive.
  4. Verify the new drive which is detected.
  5. Add the new drive to the RAID array.
  6. Start the rebuild process.
