Getting Started with Cabling

Language:

Appliance cabling comprises connections to the controller service processor (SP) network cabling, cabling between disk shelves and controllers, and cabling for cluster configuration. To access initial setup and configuration, you make a network or serial connection to Oracle Integrated Lights Out Manager (ILOM), located in the SP. All disk shelf and controller cabling must be completed before you can begin power-on and initial configuration.

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. 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 (NSPF).

Disk shelves can be added to established standalone or clustered configurations without powering down the appliance or loss of service to clients. For more information, see Adding a New Disk Shelf in Oracle ZFS Storage Appliance Customer Service Manual. After connecting the disk shelves, verify that you have redundant paths to each disk shelf.

To get started with cabling, use the following sections:

Caution - Improper orientation of mini-SAS HD cables during installation can damage the HBA connector and cause the HBA to malfunction. These cables are used with 4X4 port SAS-2 HBAs and 4X4 port SAS-3 HBAs. Position the blue release tab downward for horizontally mounted HBAs or to the right for vertically mounted HBAs. For detailed information, see Cabling Disk Shelves Together and Cabling Controllers to Disk Shelves in a Base Cabinet.
