Connecting Disk Enclosures to the Controller Enclosure
All EXP expansion ports on the storage devices only connect to the PRI expansion ports.
The expansion ports on controller A must connect to the PRI expansion ports on expansion module
A of the disk enclosure; the expansion ports on controller B must connect to the PRI expansion ports
on expansion module B of the disk enclosure.
Each 6 Gb SAS expansion port on the controller enclosure can be connected to a maximum of three
disk enclosures, each of which supports up to 25 disks.
The bend radius of the mini SAS cable should be larger than 150 mm (5.91 inches).
If the controller enclosure is connected to one or two disk enclosures: Expansion module on
controller A must connect to expansion module A on each disk enclosure. Expansion module on
controller B must connect to expansion module B on each disk enclosure.
If the controller enclosure is connected to three disk enclosures: The third disk enclosure is directly
connected to the first or second disk enclosure.
