The following figures show a subset of the supported configurations for Oracle ZFS Storage 7420 standalone controllers with four HBAs. To cable the controller to the disk shelves, see Getting Started with Cabling.
Using mixed disk shelves on a controller requires the following:
The controller must use only 4X4 port SAS-2 HBAs
Do not use mixed disk shelves in the same chain
