Drive backplane connectors
The following illustration shows the internal connectors on the drive backplanes.
Note
Some cable connectors have locks or latches that must be disengaged to disconnect the cable.
There are two types of drive backplane used in the server: one that controls only SAS drives and one that controls both SAS and NVMe drives. Cable routing for drive components is different for SAS and SAS/NVMe drives:
For information about drive backplane cable routing, see Cable routing for drives.
