Dear Luca, I've created a config with two 16 port 10GBe switches,those does not connected to each other. I have 4 hosts and 1 storage host. I don't know why, but I can't ping from all of host to all of hosts. For example I can ping from .1 to .2 but not .3! From .3 I can ping .4 but don't .1 :) I don't know the cables how is connected to the switch, but I'm sure every host connected to switches whit two inferface (one-to-one)
Thanks!
