問題文
Dynamic path selection has been turned on for the switch profile in an InfiniBand fabric, but the traffic distribution has not changed. Which condition still has to be satisfied?
選択肢
- The link speed has to be identical on every alternative path, and the mechanism compares the paths by their rated capacity and treats a slower alternative as ineligible for selection.
- The option has to be enabled in the fabric management entity as well; enabling it on the switch alone does not make it take effect.
- Every endpoint has to be reconfigured to open more than one connection between each pair of nodes, because the mechanism distributes connections rather than individual packets and a single connection between two nodes will always follow one path no matter how many alternatives exist in the topology.
- The partition membership has to be widened so that the alternative paths become reachable, since a path that crosses a switch outside the tenant's partition cannot be selected.
