How are the ports mapped from server to fabric interconnect in UCS?
Port mapping from server to fabric interconnect is automatic in UCS. If the number of links from fabric extender to fabric interconnect is only one then all of the 8 ports are pinned to it. If the number of links from the fabric extender to the fabric interconnect is two then ports 1,3,5,7 are pinned to the first link and ports 2,4,6,8 are pinned to the second link. If the number of links from fabric extender to fabric interconnect is four then ports 1,5 are pinned to the first link; port 2,6 are pinned to the second link; port 3,7 are pinned to the third link, and port 4,8 are pinned to the fourth link. Remember that the three link topology is not supported in UCS.
