CAUTION: HP SAS cables contain four data paths, which normally support up to four hard disks. When used to connect to the host SAS controller, both the HP SAS Infiniband and the HP Mini-SAS split cables divert one of these data paths to the tape drive, which means that the data path is no longer available for a hard disk drive. Take care if using this cabling configuration because you may lose the use of one of your hard disk drive bays. For detailed instructions on connecting the external SAS tape drive, see "Installing an external DAT SAS tape drive" on page 39.
