The untagged network can send tagged and untagged traffic between the server and the
interconnect simultaneously.

When you create or modify a network set, you define the maximum bandwidth and the
preferred bandwidth for connections to that network set. A server profile can override the
preferred bandwidth but not the maximum bandwidth.

When you delete a network set, the networks that belong to the network set are not affected.
However, any servers with a connection to that network set are affected because their
connections are defined as being to the network set and not to the individual networks. Because
the network set is no longer available, the network traffic to and from that server through that
connection is stopped. When you delete a network set, any server profile connections that
specified that network set become undefined.

18.5 About Fibre Channel networks

You can use Fibre Channel networks to connect to storage systems.

18.5.1 Fibre Channel network types

The Virtual Connect interconnect modules in enclosures support two types of Fibre Channel
connections to storage systems:

Fabric attach connections—The enclosure interconnects connect to data center SAN fabric
switches.

Direct attach connections—Also called Flat SAN, in which the enclosure interconnects connect
directly to a supported storage system, such as an HP 3PAR StoreServ Storage system.

You cannot change the type of a Fibre Channel network, but you can delete the network from the
appliance, and then add the network as a different type.

A logical interconnect can use both direct attach storage and fabric attach storage at the same
time.
