Technical rules for drives
Use this section to understand the technical rules for drives.
Drive installation rules
The following rules for drives provide information necessary for installing 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” on page 17.
2. The drives in a single RAID array must be of the same type (as in hard disk drives (HDD), solid-state
drives (SSD), and so on), same size, and same capacity.
3. If your server comes with rear drives, always install the rear backplane first. The drive installation should
be rear drive bay 16 → 17, and then front drive bay 0 → 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9.
4. The suggested priority of different drive types: NVMe SSD→SAS SSD→SATA SSD→SAS HDD→SATA
HDD.
5. The installation order of different drive interface types: NVMe → SAS → SATA.
6. For EDSFF drives, follow the numerical order of the drive bay sequence. Do not skip bays when installing
EDSFF drives.
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 NVMe/SAS/SATA drives in one system, install NVMe drives in a descending bay sequence
order, 9 → 8 →7...; and SAS/SATA drives in an ascending bay sequence order, 0 → 1 → 2....
