Scenario 2 Connecting high-density disk enclosures
18
 Connect two high-density disk enclosures using mini SAS HD electrical cables. The cables must be naturally bent,
and a minimum of 97 mm (3.82 inches) clearance must be reserved in front of each enclosure for winding cables.
 Standard and high-density disk enclosures cannot be connected to one expansion loop.
 Each expansion loop of high-density disk enclosures must be connected to two adjacent ports (excluding ports P1
and P2) of the 12 Gbit/s SAS interface module on a controller enclosure, for example, ports P0 and P1 or ports P2
and P3.
