Enabling and Disabling SR-IOV on NIC Ports

Note: This section only applies when running the OneCommand Manager application

on supported SR-IOV operating system platforms.

When SR-IOV is available, the NIC Port Information tab (Figure 8-45) allows you to

enable SR-IOV on NIC adapter ports. When SR-IOV is enabled, multiple virtual

functions (VFs) can be created on a NIC physical function (PF) for an adapter port.

These VF's are assigned by virtual operating systems such as Microsoft Hyper-V and

Linux KVM to virtual machines (VMs). Each VM can be assigned one or more VFs by

the guest operating system running on the VM. To the guest operating system, the VF is

an independent NIC function with its own MAC address and is available for network

I/O.

The discovery-tree displays the VFs running on the discovered PFs. It also shows the

selected VFs MAC Address, VLAN ID, Link Status and Transmit Rate.

To enable or disable SR-IOV:

1. Select Host or Virtual Ports view

Note: In Virtual Ports view, NIC ports only appear on FCoE adapters. They do not

appear on iSCSI or NIC-only adapters.

2. Select a NIC-Only adapter in the discovery-tree.

3. Select the Port Information tab.
