How to Connect Disk Shelf and Controller Cables
2.
If clustered controllers, repeat to perform an SP connection for the second
controller.
3.
Connect an Ethernet cable from the NET-0 port on the rear panel of the controller
to your Ethernet switch.
4.
If clustered controllers, connect an Ethernet cable from the NET-1 port on the
second controller to your Ethernet switch.
How to Connect Disk Shelf and Controller Cables
Use the following procedure to connect the cables between storage controller(s) and disk
shelves.
Caution - Do not connect the power cables until instructed to do so in “Powering On the
Appliance” on page 119.
The cabling configuration for your appliance depends on the number and type of controllers and
disk shelves, as well as the number of host bus adapters (HBAs) in your system. Disk shelves
attach to other disk shelves with daisy-chained serial attached SCSI (SAS) cables. Controllers
attach to each disk shelf chain with a longer SAS cable connected via HBAs located in specified
PCIe slots of the controllers. Clustered controllers are attached via three Ethernet cables that
provide redundant communication channels: two serial links and an Ethernet link. The cabling
methodology designed for the appliance includes bottom-to-top cabling for easier growth with
optimum safety, strategic slot placement for optimum load distribution and performance, and
interface redundancy for clustered controllers, ensuring no single point of failure.
1.
Locate the appropriate cabling configuration for your system in the Oracle ZFS
Storage Appliance Cabling Guide.

Connect cables between disk shelves and between storage controller(s) and
disk shelves.
If clustered controllers, be sure to connect the cluster cables as described in Connecting the
Cluster Cables in Oracle ZFS Storage Appliance Cabling Guide.
