Technical rules for drives

Understanding the technical rules for drives helps you correctly install and configure drives in the system.

Drive installation rules​

The following rules for drives provide information that you must consider when you install a drive.

General rules​

  1. The drive bays are numbered to indicate the installation order (starting from number “0”). Follow the installation order when you install a drive. See Front view for more details.

  2. The drives in a single RAID array must be of the same type (as in hard disk drives, solid-state drives, and so on), same size, and same capacity.

Mixing rules​

  1. You can use drives from different vendors.

  2. You can mix drives of different types and different capacities in one system, but not in one RAID array. And when you deploy a drive mix, install drives of lower capacity first.

  3. When mixing 1T and 2T E3.S drives, at least one 1T E3.S drive should be installed.
