General Management with NIC Partitioning
Use the NIC Partitioning (NPAR) feature to manage the QME8242 as described in
the following section.
NIC Partitioning (NPAR)
This section provides the following information about the QLogic NIC Partitioning
(NPAR) feature:
 Overview
 Configuration and Operation
Overview
The NPAR feature in QLogic adapters provides the ability to create multiple PCIe
physical functions for each physical 10 GbE port on the adapter. Each of the PCIe
functions appears as an independent interface to the host operating system or
hypervisor.
Dual-port, 10 Gb adapters configured as Ethernet-only adapters contain eight
Ethernet functions. QME8242 configurations can contain up to four Ethernet
functions corresponding to each physical port.
Configuration and Operation
By default, NPAR functionality is disabled on the adapters. Only two Ethernet
functions are enabled. Depending on the feature personality mapping supported
on the adapter, you can enable additional Ethernet or storage functions. The PCI
function number assignment is as follows:
 Functions 0 and 1 are always NIC functions.
 Functions 4 and 5 are iSCSI functions if iSCSI is enabled.
 Functions 6 and 7 are FCoE functions if FCoE is enabled.
 If iSCSI and FCoE functions are not enabled, they are available to be
configured as NIC functions.
 Only one iSCSI function per physical port.
 Only one FCoE function per physical port.
The PCI function to port mapping is also fixed as follows:
 Functions 0, 2, 4, and 6 share one physical port.
 Functions 1, 3, 5, and 7 share the other physical port.
When performed, the following operations require a system reboot to take effect:
 Enabling or disabling NPAR mode
 Changing function type (iSCSI to NIC, FCoE to NIC, or NIC to FCoE)
