A technician is working with a storage array that has 15 total slots for hard drives. The technician is tasked with configuring two separate RAID 5 volumes of the same size, sharing a global hot spare

With 15 total drives and one dedicated as a global hot spare, 14 drives remain for data. These 14 drives are split to form two separate, identical RAID 5 volumes, meaning each volume utilizes 7 drives. For a RAID 5 configuration with 7 x 1TB drives, one drive's capacity is used for parity, resulting in a usable capacity of (7-1) * 1TB = 6TB per volume.

7 TB would represent the total raw capacity of the seven drives allocated to a single RAID 5 volume, but it does not account for the one drive's capacity lost to parity in a RAID 5 setup.

7.5 TB is not attainable under these specific constraints and drive configurations, as it does not align with an integer number of drives or standard RAID 5 capacity calculations.

8 TB of usable capacity would typically require 9 drives in a RAID 5 configuration (8 data + 1 parity), but only 7 drives are available per volume in this scenario after allocating the hot spare.
