I was wondering if there is a guide that outlines how to cable 2 or more stacks of disk shelves on a 3240 with onboard SAS ports + a quad port SAS adapter in slot 1, specifically what ports to use for each stack. I looked at the Universal SAS cabling guide, but did not see this specific scenario. Since there is not a C port onboard, what would you use for the next top connection after the 0a and 1a ports are used ?
The documentation in the storage subsystem technical faq is to shift the bottom row of b/d ports to the left and wrap around the first entry... so the port pairs would be 0a/1b, 1a/1d and 1c/0b. The 1a/1d being less desirable on the same hba, but suported since on a different asic pair on the card.
