Q-Logic 8200, 3200 manual Enabling NPAR, Quality of Service

2–Configuring NIC NIC Partition (NPAR)

Enabling NPAR

To enable NPAR for a port in the QLogic vCenter Plug-in, do the following:

1.Select function 2 for port 0 and function 3 for port 1.

2.Click OK to accept the NPAR parameter(s) Successfully Changed! confirmation message.

3.Reboot the ESX Host.

NOTE:

This is the Server where the Converged Network Adapter or Intelligent

Ethernet Adapter is installed.

4.Wait until the ESX Host again becomes connected in the Data Center. The ESX Host's Name (IP Address) will be italicized (not responding) while the ESX Host reboots.

5.After the ESX Host connects again, on the shortcut menu on the QLogic Adapter tab, click Refresh.

Function 2 of port 0 is now configured for NIC; this enables NPAR.

NPAR enabled on port 0—function 2 on port 0 is enabled.

NPAR disabled on port 1—function 3 on port 1 is disabled.

NPAR is now enabled, and the configuration range of the FCoE and iSCSI storage functions is extended. The FCoE Function Type options are extended FCoE, NIC, and Disabled (see Figure 2-22).

Quality of Service

The QLogic vCenter Plug-in provides control of the NPAR quality of service (QoS) capability of the 8200 and 3200 Series Adapters. QoS is enabled whenever FCoE is not enabled. This is because FCoE requires ETS, which supersedes NPAR's QoS.

The vCenter QoS controls allocate bandwidth to NIC functions in increments of 1 percent of 10Gb. There is a Maximum Bandwidth control and a Bandwidth Weight. The Maximum Bandwidth control specifies the maximum bandwidth that the NIC function is allowed take in congested conditions. A NIC function can take more bandwidth than the Maximum Bandwidth setting if there is no other demand for that bandwidth. The Bandwidth control specifies the minimum band width that a NIC function is guaranteed in congested conditions.
