OCe14100–Series Adapters

You can switch between showing eight functions and showing sixteen functions for a
given adapter, if NPar is enabled. If you know whether you are in an NParEP Mode
configuration, you can display the appropriate number of functions for an adapter.
NPar protocol assignments are subject to the following rules:

The first channel can only be assigned NIC protocols. The first channel cannot
be assigned None.

The second and third channels can be assigned the following:

NIC

None (channel disabled)

Storage protocol (note: on 3rd channel only when concurrent mode storage
is available)

The fourth and higher channels (if available) can only be assigned NIC or None
(channel is disabled).

The total of the minimum bandwidths of the enabled functions for each port
must add up to 100 percent. The maximum bandwidth for each function must
be greater than, or equal to, the minimum bandwidth for that channel.

After changing the NPar configuration and applying the changes, except for
bandwidth changes, a reboot is required to activate the new configuration.

SR-IOV must be disabled on the adapter BIOS when NPar is used. See “Using
SR-IOV on NIC Ports” on page 106 for information on disabling SR-IOV on the
adapter BIOS.

SR-IOV must be enabled on the system BIOS when NParEP is used. See the
documentation that accompanied your Dell server for more information.

NParEP support is available only on Dell 13G or newer systems.
