and boot code to run, which then enables Virtual Connect to configure the "Dynamic Changes to FlexNICs"
feature.
The Allocated Bandwidth column displays "not allocated" until the profile is assigned to a device bay that
contains a server. At that time, bandwidth is allocated to each connection and the result is reported in this
column. See "Bandwidth assignment (on page
)."
The Mapping column describes how each connection of a profile is assigned to physical devices in a server
and to which interconnect bay that device is connected. The four FlexNICs on port 1 of a server LOM that
supports Flex-10 are numbered LOM:1-a, LOM:1-b, LOM:1-c, and LOM:1-d. If a LOM does not support
Flex-10, then it is simply referenced by its port number (for example, LOM:1 or LOM:2).
FlexFabric overview
VCM 3.15 and higher supports the HP VC FlexFabric 10Gb/24-port Module. This module provides eight
uplinks, four of which can be designated as either Fibre Channel or Ethernet. The remaining 4 uplinks are
Ethernet-only uplinks. It is now possible to include one FC connection and three Ethernet connections on a
single 10Gb port. However, both the server and switch hardware must support FlexFabric. In addition to the
existing NICs and LOMs, this module functions with FlexFabric mezzanine cards and embedded FlexFabric
LOMs.
FlexFabric module uplink ports X1-X4 can be configured as FC fabric ports or Ethernet network ports. If a port
is configured as an FC fabric port, the protocol used is FCoE, and the server profile connection to that fabric
is an FCoE connection.
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 SFP-FC connector
is required. SFP speeds of 2Gb, 4Gb, or 8Gb are supported for this configuration. A 1G SFP connector is not
supported on ports X1-X4 for either Ethernet or FC configurations. For Ethernet ports, the 10GbE SFP-LRM
pluggable module is not supported on ports X1-X4. The Ethernet SFP-LR and SFP-SR are supported on all
ports.
