Chapter 6. Controller-to-stack cabling worksheet and cabling
example for a quad-path HA configuration with two quad-port
SAS HBAs
You can use the completed controller-to-stack cabling worksheet and cabling example to cable a quad-path
HA configuration that has two quad-port SAS HBAs.
• If needed, you can refer to the “SAS cabling rules” section for information about supported configurations,
the controller slot numbering convention, shelf-to-shelf connectivity, and controller-to-shelf connectivity
(including the use of port pairs).
• If needed, you can refer to the “How to read a worksheet to cable controller-to-stack connections for
quad-pathed connectivity” section.
• The cabling example shows controller-to-stack cables as solid or dashed to distinguish controller A and C
port connections from controller B and D port connections.
• Cables in the cabling examples and their corresponding port pairs in the worksheets are color-coded to
distinguish connectivity to each stack in the HA pair.
