Question

A systems administrator has deployed a Dell Unity XT 380F system with 15x 1.92 TB SSD drives, in a RAID 5 dynamic pool. Shortly after deployment, the administrator wants to expand the capacity of the system and use larger drives to increase the density. What will happen if the administrator adds 4x 3.84 TB SSD drives?

Options

  • AThe full capacity of the drives will be available.
  • BOnly half of the capacity of the new drives will be available.
  • CThree of the drives will be added with a fourth reserved as spare.
  • DThe mixing of drive types is not supported, and the operation will fail.
