12–SR-IOV
Enabling SR-IOV

SR-IOV and Storage

Storage (FCoE or iSCSI) can be enabled on an SR-IOV-enabled adapter.
However, if storage is used on an NPAR-enabled physical function (PF), then the
number of virtual functions for that PF is set to zero; therefore, SR-IOV is disabled
on that PF, and the other PFs on that port can support SR-IOV VF connections.
This limitation applies only when the adapter is configured in NPAR mode. It is not
relevant when the adapter is configured in single-function mode.

SR-IOV and Jumbo Packets

If SR-IOV is enabled on a virtual function (VF) on the adapter, ensure that the
same jumbo packet settings is configured on both the VF and the Microsoft
synthetic adapter. You can configure these values using Windows Device
Manager > Advanced properties.
If there is a mismatch in the values, the SR-IOV function will show as Degraded in
Hyper-V > Networking Status.
