DD640, DD670, DD860, and DD890 systems
SAS HBA ports
The figure below shows the rear panel of these Data Domain systems with the location
of PCI cards. SAS cards are installed in PCI slots 1, 2, and 3. Each SAS card has four
ports (D, C, B, A). The ports are 1a, 1b, 1c, and 1d; 2a to 2d; and 3a to 3d.
Only the Data Domain DD860 controller with DD Extended Retention software
(formerly called the DD860 Archiver) has three quad-port SAS cards installed. The
other systems have two quad-port SAS cards.
