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.
