| Controller-to-stack cabling worksheets and cabling examples for common HX2000 configurations |
Multipath configuration with one multi-shelf stack
The following worksheets and cabling examples use port pair 0a/0b.
In this example, the controller is installed in slot A of the chassis. When a controller is located in slot A of the
chassis, its internal storage port (0b) is in domain A (IOM A); therefore, port 0b must connect to domain A
(IOM A) in the stack.
