Advantages of SR-IOV
SR-IOV devices can share a single physical port with multiple virtual
machines.
When an SR-IOV VF is assigned to a virtual machine, it can be
configured to (transparently to the virtual machine) place all network traffic
leaving the VF onto a particular VLAN. The virtual machine cannot detect that
its traffic is being tagged for a VLAN, and will be unable to change or
eliminate this tagging.
Virtual Functions have near-native performance
and provide better performance than paravirtualized drivers and emulated
access. Virtual Functions provide data protection between virtual machines on
the same physical server as the data is managed and controlled by the
hardware.
These features allow for increased virtual machine density on
hosts within a data center.
SR-IOV is better able to utilize the
bandwidth of devices with multiple guests.
