Multipath HA with four onboard SAS ports, a quad-port SAS HBA, and two multi-shelf stacks
Four port pairs are available for this configuration: 0a/1b, 1a/0d, 0c/1d, and 1c/0b. You can cable port pairs in
the order in which they are identified (listed in the worksheet) or you can cable every other port pair (skip port
pairs).
When you have more port pairs than you need to cable the stacks in your system, the best
practice is to skip port pairs to optimize the SAS ports on your system. By optimizing SAS ports,
you optimize your system’s performance.
The following worksheet and cabling example shows port pairs being used in the order in which they are listed
in the worksheet: 0a/1b, 1a/0d, 0c/1d, and 1c/0b.
