Hard Drive Backplanes; Removing The Hard Drive Backplane - Dell PowerEdge C6320p Owner's Manual

Hard drive backplanes

Servers use a backplane to attach hot swappable hard drives. A backplane has pins that pass directly into hard drive sockets without
cables. They may have single connector to connect one disk array controller or multiple connectors that can be connected to one or
more controllers.
