VPD Table Definitions

Product Name – The product information about a selected adapter port.

Part Number – The adapter's part number.

Serial Number – The adapter's serial number.

VO – Vendor unique data. “V” indicates a vendor-specific field. An adapter
may have none, one or more of these fields defined. Valid values for this field
are “VO” (the letter “O”, not the number zero) and “Vx” (where “x” is a
number).
Note: Some adapters may show additional VPD information such as engineering
change (EC) level and MN (manufacturer ID).
Using SR-IOV on NIC Ports
When SR-IOV is available, the NIC Port Information tab (Figure 6-36) allows you to
enable SR-IOV on NIC adapter ports. When SR–IOV is enabled, multiple VFs can be
created on a NIC PF for an adapter port. These VF's are assigned by the ESXi host to the
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.
Enabling or Disabling SR-IOV
To enable or disable SR-IOV:
1. Select Host view.
2. Select a NIC port function on an adapter in the discovery-tree.
3. Select the Port Information tab.
4. Click Enable SR-IOV or clear the Enable SR-IOV checkbox. See Figure 6-36 on
page 101.
Notes:

SR-IOV is not supported with UMC channel management; they are mutually
exclusive. If you set channel management, then you must disable SR-IOV. If you
set SR-IOV, then you must disable channel management.

To use SR-IOV, you must enable SR-IOV in OneCommand Manager for
VMware vCenter and the system BIOS. See the Emulex Drivers for VMware ESXi
User Manual for information on enabling SR-IOV in the system BIOS.

If you disable SR-IOV from the Port Information tab by clearing the Enable
SR-IOV checkbox, the operating system or port stops supporting SR-IOV after
reboot.

A system reboot is required to change the SR-IOV state.
