HP VC FlexFabric
Because of the many possible configurations of the FlexFabric module, pluggable modules can differ for each uplink port on the FlexFabric module. If the uplink port is being used for an FC fabric, an

When an available port is used for Ethernet, it is no longer available for FC configuration, and
The FlexFabric VC module requirements also imply some additional constraints with current
On the NC551i LOM and the NC551m mezzanine card, there is a limitation. FCoE and iSCSI connections are not supported on the same adapter at the same time. By default, if a FlexFabric module is found in the enclosure, FCoE connections are created for each server profile. If you do not want to configure FCoE connections, delete the default connections to allow the ports to be used for other connections, such as iSCSI or additional Ethernet connections. To delete the connections,
There are additional limitations with the supported LOMs and mezzanine cards that support FlexFabric configurations. Both FCoE boot and PXE can be configured on the same port with the NC551i LOM and the NC551m mezzanine card on different physical functions. Alternatively, iSCSI and PXE can be configured on the same port. Only one physical function can be configured for FCoE on a port.
When configuring FCoE connections, the port speed can be set to 1Gb, 2Gb, 4Gb, 8Gb, custom, preferred, or disabled. The port speed is limited to a total of 20Gb, which must be shared between all defined connections for that port. The custom speed allows you to better control the bandwidth between FC and Ethernet connections. Valid custom speeds are between 100Mb and 10Gb, in 100Mb increments. After all connections are defined for a port, the actual allocated bandwidth is calculated by VCM. For bandwidth information, see “Bandwidth Assignment (on page 175)."
