• If needed, you can refer to
convention, shelf-to-shelf connectivity, and controller-to-shelf connectivity (including the use of port pairs).
• If needed, after you complete the worksheet, you can refer to
to-stack connections for quad-pathed
Steps
1. In the boxes above the gray boxes, list all SAS A ports on your system, and then all SAS C ports on your
system in sequence of slots (0,1, 2, 3, and so on).
For example: 1a, 2a, 1c, 2c
2. In the gray boxes, list all SAS B ports on your system, and then all SAS D ports on your system in
sequence of slots (0,1, 2, 3 and so on).
For example: 1b, 2b, 1d, 2d
3. In the boxes below the gray boxes, rewrite the D and B port list so that the first port in the list is moved to
the end of the list.
For example: 2b, 1d, 2d, 1b
4. Identify the two sets of port pairs to connect to stack 1 by drawing an oval around the first set of port pairs
and a rectangle around the second set of port pairs.
Both sets of cabling are needed to achieve quad-pathed connectivity from each controller to stack 1 in your
HA pair or single-controller configuration.
The following example uses port pair 1a/2b for the multipathed cabling and port pair 2a/1d for the quad-
pathed cabling to stack 1.
