NPar enables the capability to divide a 10Gb port into multiple physical functions, with
flexible bandwidth capacity allocation, that appear to the operating system and
network as separate physical devices.
Adapter Configuration
NPar can be configured on OCe14000-series adapters through the adapter BIOS or the
OneCommand Manager application.

To configure NPar using the adapter BIOS, see the Boot for NIC, iSCSI, FCoE, and
RoCE Protocols User Manual.

On the host operating system side, NPar provides up to 16 physical functions per
device, when NParEP is enabled, using the standard PCI configuration space. The
number of physical functions that can be mapped to a physical port depends on the
adapter:

Four-port adapter = four physical functions

Two-port adapter = eight physical functions
Each physical function or partition is assigned a unique MAC address.
Partitions are available for virtual function assignment and for application
segmentation via VLAN or IP subnets.
Adapter Requirements

The partitions can be on separate subnets or VLANs

Bandwidth allocation is flexible

No operating system or BIOS changes required

No external switch changes required

Each partition should have standard NIC properties for stateless offload
The following items are supported on a per-partition basis:

Per-partition statistics

TSO required per partition

MTU per partition

Support for NetQueues
