Drive tray cabling topologies for the E2612 controller-drive tray and the
E2624 controller-drive tray
Depending on the number of drive trays that you need to connect, see the applicable figure for a
cabling topology. Each example shows a duplex controller-drive tray configuration with redundant
paths to the drive trays. For a simplex controller-drive tray configuration, use the cabling topology
shown for controller A in the applicable figure.
The following figures show the SAS ports on a DE1600 drive tray or a DE5600 drive tray.
Note:
You can connect either of the SAS ports labeled SAS 1 and SAS 2 to the SAS expansion port on
another drive tray or on a controller-drive tray. You should not make connections to both the SAS 1
port and the SAS 2 port on the same ESM.
