Connecting DS60 shelves
The cabling diagrams in this section show maximum configurations. Not all systems will have all the disk shelves shown in the
diagrams.
When connecting DS60 shelves, all the cables have HD-mini-SAS connectors at both ends.
Add shelf-to-shelf cables between shelves in a loop and to the controller as shown in the diagrams.
CAUTION: When connecting SAS cables to the SAS cards, ensure there is sufficient slack in the cable to avoid
unnecessary strain on the cable connector and the SAS card when the controller is fully extended from the rack.
Connect an FS25 shelf with DS60 shelves (HA systems)
Connect the FS25 shelf to the controller as shown in the diagrams.
● Cable the SSD shelf on its own loop, separate from the DS60 shelves.
● The SSD shelf counts towards the total number of shelves connected to the system.
DD6900 with DS60 cabling
The diagram shows the system cabled in a single set. The FS25 SSD shelf is cabled separately from the DS60 shelves.
