If needed, you can refer to SAS cabling rules and concepts for information about supported configurations, shelf-to-shelf connectivity, and controller-to-shelf connectivity.
-
Cabling examples show controller-to-stack cables as solid or dashed to distinguish controller 0b/0b1 port connections from controller 0a port connections.
-
Cabling examples show controller-to-stack connections and shelf-to-shelf connections in two different colors to distinguish connectivity through IOM A (domain A) and IOM B (domain B).
FAS2820 platform in a multipath HA configuration with no external shelves
The following example shows that no cabling is needed to acheive multipath HA connectivity:
FAS2820 platform in a tri-path HA configuration with no external shelves
The following cabling example shows required cabling between the two controllers to achieve tri-path connectivity:
FAS2820 platform in a tri-path HA configuration with one multi-shelf stack
The following worksheet and cabling example uses port pair 0a/0b1:
Platforms with internal storage in a multipath HA configuration with one multi-shelf stack
The following worksheet and cabling example uses port pair 0a/0b:

FAS2600 series 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.
In this example, the controller is installed in slot B of the chassis. When a controller is located in slot B of the chassis, its internal storage port (0b) is in domain B (IOM B); therefore, port 0b must connect to domain B (IOM B) in the stack.
