Archi-TECH discussed virtual bottlenecks and the multipathing feature in Virtual Iron 4.2:

Virtualization system vendors are finally taking the impact their technology is having on the network seriously, responding with novel ways to ensure that multiple virtual servers have equal access to network resources, particularly storage, without overwhelming existing infrastructures.

...

One of them is multipathing, which can be found on the Virtual Iron 4.2 to connect virtual machines to either Ethernet or Fibre Channel networks as a means to boost redundancy and business continuity. In a multipath environment, data is split along separate I/O paths so individual network interconnections don’t get bogged down.
