Drive backplanes

The server supports the following types of drive backplanes:

SAS/SATA drive backplanes—Support only SAS/SATA drives.

UniBay drive backplanes—Support both SAS/SATA and NVMe drives. You must connect
both SAS/SATA and NVMe data cables. The number of supported drives varies by drive
cabling.

X SAS/SATA+Y UniBay drive backplanes—Support SAS/SATA drives in all slots and support
NVMe drives in certain slots.
X: Number of slots supporting only SAS/SATA drives.

Y: Number of slots supporting both SAS/SATA and NVMe drives.

For UniBay drive backplanes and X SAS/SATA+Y UniBay drive backplanes:

The two drive types are supported only when both SAS/SATA and NVMe data cables are
connected.

The number of supported SAS/SATA drives and the number of supported NVMe drives vary by
cable connection.
