Table 11-2 details the different types of ports in the IBM Flex System Fabric CN4093 10Gb
Converged Scalable Switch.

Ports
(External)
The Omni ports are all by default in Ethernet mode and can carry Ethernet traffic as well as
FCoE. These ports can be configured as FC ports and attach to external storage controllers
or servers. They must be configured in pairs for either Ethernet or FC mode, for example, port
EXT11 and EXT12 must both be configured to be in the same mode and so are called paired
ports.
Fibre Channel VLANs
The ports that will be used to connect using FCoE must be isolated into a separate VLAN on
the IBM Flex System Fabric CN4093 10Gb Converged Scalable Switch. The VLAN, when
defined, must have a VLAN number and the following components:
Port Membership: Named ports, as detailed in Table 11-2; the VLAN must include at least
one FC defined port (paired FC Omni ports can reside in a separate FC VLAN).
Switch Role: Either full switch fabric or NPV mode.
The switch role mode for that VLAN will determine whether it has the switching element, thus
FCF capability; or has to pass all data to an external SAN switch for redirection, thus NPV
capability. For a compute node to connect to IBM Flex System V7000 Storage Node and
access storage, the VLAN must have FCF enabled. Thus, all storage data will remain within
the IBM Flex System Enterprise Chassis and not have to rely on an external SAN switch for
its switching or redirection.
Figure 11-12 shows VLAN 1002, which has been created and includes external ports EXT11
and EXT12 along with internal ports from the IBM Flex System V7000 Storage Node
canisters. The storage node occupies node ports 1-4 in the IBM Flex System Enterprise
Chassis so ports INTA1-4 are available for this VLAN, of which INTA3+4 have been selected.
The port from Compute Node 11 (INTA11) has also been included in the Fibre Channel
VLAN.

Description
These standard 10 Gb SFP+ Ethernet ports
connect internally to compute nodes and
storage in the system chassis.
These standard 10 Gb SFP+ Ethernet ports
provide external connectors.
These 40 Gb QSFP+ Ethernet ports can be
configured as either two 40 Gb Ethernet ports
(EXT15 and EXT19), or as four 10 Gb Ethernet
ports (EXT15-EXT18, EXT19-EXT22).
These 10 Gb SFP+ hybrid ports can be
configured to operate either in Ethernet mode
(the default) or in Fibre Channel mode for direct
connection to Fibre Channel devices.
