Why doesn't InfiniBand offer a routed fabric? Or was this the result of some "booty splitting arrangement" where the Ethernet folks got switching & routing and the InfiniBand folks - just because they offer more bandwidth - only got the switching capability?
There are many reasons why a routed fabric is more advantageous over a switched fabric, especially in light of the fact that InfiniBand offers all this bandwidth. Or is InfiniBand just fast only because it is a switched fabric? Well, application level QoS that's possible through IPv6 can only be applied on a routed fabric, and I'm counting on that capability for the buildout of my datacenters. And I would absolutely want to use InfiniBand all throughout my datacenters, so what's the best option that I have?
