The following items are supported on a per-partition basis:

Statistics

LSO, LRO, RSS, TSO, and MTU

Support for NetQueues

NPar Considerations

NPar can use virtual adapters using VLAN tagging per partition.

NPar can use RSS queuing support per partition.

DCBX is supported while in NPar mode.

If iSCSI or FCoE functions are not enabled, they are available as NIC functions.

Only one iSCSI function is allowed per physical port.

Only one FCoE function is allowed per physical port.

Each function has at least one unique MAC address.

The second to fourth functions on a particular port are available for storage

protocols if desired; allowing you to configure up to two storage functions.

When NParEP is disabled, a total of 8 functions are available evenly distributed

across the ports on the adapter. For example, a 2-port adapter can have 4

functions /port and 4-port adapter can have 2 functions/port. When NParEP is

enabled, a total of 16 functions are available evenly distributed across the ports

on the adapter. For example, a 2-port adapter can have 8 functions/port and

4-port adapter can have 4 functions/port.

Note: A system reboot is required if any of the NPar function mode settings are

modified. A reboot is not required for bandwidth and MTU settings

modifications.

Enabling NPar Using the Multichannel Property Page

You can enable NPar on a port using the Multichannel property page. Each port is

represented by a tab on the Multichannel property page that lists all of the available

PCI functions for a particular port. The list of PCI functions displayed depends on the

multichannel mode.

Note: When provided by the switch, the driver accepts the QoS setting as set by DCBX

for the minimum committed bandwidth instead of the minimum bandwidth

configured on each partition in the Multichannel tab. If there are multiple NIC

functions in an NPar configuration with storage and NIC functions together, the

committed minimum bandwidth for NIC will be divided equally between all

NIC functions, and the storage bandwidth will be assigned to the storage

functions as applicable.

From the Multichannel property page, you can:

Enable or disable NPar using the Mode list.

Enable or disable NParEP.
