SAS hard drive cabling

The HP ProLiant DL385 Server SAS model uses a serial attached SCSI bus to connect SAS hard drives on a SAS backplane to a PCI SAS controller. In a SAS environment, each hard drive has a direct connection to the SAS controller. Two cables connect the PCI SAS controller to the SAS backplane. Each cable controls four SAS drives.

NOTE: If storage devices are connected to both the internal (1I) and external (1E) SAS connectors, the SAS controller recognizes only the devices connected to the internal connector. To attach devices to the external connector, disconnect the internal connector. Refer to the documentation that documentation that ships with the controller.
