we setup a small Infiniband fabric using two switches QM8700. We’ll connect the switches on ports 1-6 and use 7-40 to connect host ports. Can we just use the default minhop routig engine or do we need to use something more advanced like LASH to get this working? I want to make sure that we get routes passing between switches, i.e. that all hosts on switch A can reach hosts on switch B. ;-) We’ll run the subnet manager on the QM8700 switch itself, with just about 40 host ports this should be fine.
