
The BW[%] column lists the maximum bandwidth that a PCI function can use as
a percentage of the total port bandwidth.

The Name column provides a friendly device name if possible. Otherwise, it is a
device name or a generic operating system device class name.

NParEP — enables NParEP. See “Using NParEP” on page 649 for more
information.
Criteria for Making PCI Function Modifications

The first PCI function on each port cannot be disabled.

The sum of the minimum bandwidth values of every enabled PCI function must
be 100%.

A minimum bandwidth of 0% is acceptable, which means that the partition does
not have a guaranteed bandwidth assigned.

The minimum bandwidth cannot be greater than the maximum bandwidth
specified on a PCI function.

Each port can be configured to run up to two storage functions as long as they
are different storage protocols.
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 setting
modifications.
Using NParEP
Notes:

NParEP support is available only on Dell 13G or newer systems when NPar is
enabled.

NParEP is available only on OCe14000-series adapters.

On a four-port adapter, ARI functionality must be enabled in the PCIe
subsystem on a particular system to support NParEP on all four ports.
PCI functions are displayed in the Windows Device Manager based on how this option
is set. By enabling NParEP, you can expand the PCI functions of the adapter. See
“Enabling NPar Using the Multichannel Property Page” on page 645 for more
information.
