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.
