SR-IOV enables the adapter to
allocate virtual PCI functions for
each virtual machine in Hyper-V.
Note that the virtual switch and
virtual network adapter must have
SR-IOV enabled in the Hyper-V
Manager. SR-IOV requires a
platform with IOMMU
virtualization (VT-d, AMD-Vi).
When using SR-IOV, the Emulex NIC
driver must be installed on each
virtual function within the virtual
machine. SR-IOV provides a direct
hardware interface from the
virtual machine to the networking
adapter, which reduces latency
and improves performance.
The Windows Server 2012 and
Windows Server 2012 R2 SR-IOV
architecture establishes each
Emulex virtual NIC with a
corresponding emulated NIC. This
allows the virtual machine to
seamlessly failover to the
emulated NIC if SR-IOV is disabled.
It also allows Live Migration to
another system, regardless of the
installed NIC hardware.
Note: The driver currently
supports the following
virtual functions for the
following adapter families:

OCe11100-series adapters
support a maximum of 24
virtual functions/port.

OCe14000-series adapters
support a maximum of:
 2-port 10 Gb: 31 virtual
functions/physical
function.

4-port 10 Gb: 31 virtual
functions/physical
function
 1-port 40 Gb: 63 virtual
functions/physical
function
