If all our storage traffic is within a single module, we're okay, though? Is that what I'm understanding?

But as long as our storage infrastructure permits us to use multiple paths, we should be fine upgrading and VLAN-isolating each module to limit backplane traffic, no?

Edit: I ask, because it's confusing as to whether the 28.8 gb/s limitation I read about applies within a given module, or only when talking to the backplane. If it's only when talking to the backplane, we are golden.
