NPar Configuration (Dell Only)
Notes:

NPar is available only on OCe14000-series adapters.

When NPar is enabled, RoCE cannot be configured on any function.

Each partition should have standard NIC properties for stateless offload.

SR-IOV must be disabled on the adapter BIOS when NPar is used. See the
following documentation for information on disabling SR-IOV on the adapter
BIOS:

To configure SR-IOV using the adapter BIOS, see the Boot for NIC, iSCSI,
FCoE, and RoCE Protocols User Manual.

To configure SR-IOV using the OneCommand Manager application, see the
OneCommand Manager Application User Manual or the OneCommand Manager
Command Line Interface User Manual.
NPar enables you to divide a 10Gb NIC port into multiple PCI functions with flexible
bandwidth capacity allocation that appears to the operating system and network as
separate NIC ports. For example, a single Ethernet 10Gb port appears as multiple
physical devices showing in PCI configuration space as multiple functions.
Adapter Configuration
NPar can be configured on OCe14000-series adapters in several ways, including the
Emulex adapter driver properties, the adapter BIOS, or using the OneCommand
Manager application.
See the
Boot for NIC, iSCSI, FCoE, and RoCE Protocols User Manual for information
on configuring the adapter BIOS. If you are using the OneCommand Manager
application, see the OneCommand Manager
Application User Manual.
On the host operating system side, NPar provides up to sixteen PCI functions per
device using standard PCI configuration space when NParEP is enabled. Four PCI
functions can be mapped to a physical port on a 4-port adapter. Eight PCI functions can
be mapped to a physical port on an 2-port adapter. Each function or partition is
assigned a unique MAC address.
Partitions are available for virtual function assignment and for application
segmentation using VLAN or IP subnets. The partitions can be on separate subnets or
VLANs.
NPar Partition Support

Flexible Bandwidth allocation with no changes required for operating system or
BIOS.

The switch is independent, with no changes to the external switch required.

NIC teaming is supported.
