What is the minimum number of disks required to implement a RAID 1 for the boot partition and a RAID 5 for the data partition?

To implement RAID 1 for the boot partition, at least two disks are needed. RAID 1 mirrors data across the disks, so redundancy is achieved by duplicating the same data on both drives. This setup ensures that if one disk fails, the system can continue to operate using the other disk.

For the data partition using RAID 5, a minimum of three disks is required. RAID 5 uses block-level striping with distributed parity, which allows data to be reconstructed in the event of a single disk failure. Each of the disks in a RAID 5 array stores a portion of the data and also parity information that provides redundancy.

When you combine both configurations, you need a total of five disks: two for the RAID 1 boot partition and three for the RAID 5 data partition. This configuration ensures that both the reliable boot partition and the robust data partition are supported and operate correctly.

This total of five disks facilitates a functional and redundant system across both the boot and data partitions, aligning with the requirements set by the respective RAID levels.
