v ▌1▐ LEDs
v ▌2▐ SAS ports
Each canister has two SAS ports that are numbered 1 on the left and 2 on the right.
Port 1 is used to connect to a SAS expansion port on a node canister or port 2 of
another expansion canister.
Support rails and enclosures
Storwize V5000 Gen2 systems use the same rails and enclosures for both control
and expansion enclosures. All Storwize V5000 Gen2 models use the same
expansion enclosure.
v The ledge on the inside of each rail supports the entire length of an enclosure.
v The enclosure support rails capture the left and right rear edges of an inserted
enclosure. This prevents the installed enclosure bouncing when the rack is
subjected to quake or vibration.
v The enclosure support rails adjust to fit racks from 595 mm to 755 mm deep,
measured between the front and rear rack rails.
