Appliance" on page
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.
