The figures in this section show representative cabling configurations. The configurations
shown guarantee that redundant data paths exist between the controller-drive tray and all
attached drive trays in a storage array. You can attach the E2712 controller-drive tray to the
following drive trays: DE1600 drive trays or DE6600 drive trays.
You need two or four SAS cables to attach one or two drive trays to the controller-drive tray.
For each additional drive tray, you need two more SAS cables.

ESM B
All cables connect a SAS Expansion (Out) port at one end to a SAS IN port at the other
end. Never connect a SAS Expansion (Out) port to another SAS Expansion (Out) port.
Never connect a SAS In port to another SAS IN port.
–
You can use either of the two SAS IN ports on an ESM for a connection, but it is best
to follow the conventions described in the documentation so your storage
management software represents the storage array consistently.
The drive trays in the chain of connections from controller A are in the reverse order from
those whose connections start from controller B. That is, the last drive tray in the chain
from controller A must be the first drive tray in the chain from controller B.
