Port
The physical connection to the network. A CNA may have
two physical connections; this configuration is often
described as “dual-ported.”
CNA overview
The CNA is a PCIe device that can be configured by HP-UX as a number of LAN and FCoE devices
depending on the system configuration. Most CNAs are dual-ported. Each port represents a single
wired connection to a piece of network hardware, as follows:
•
In a Blade Virtual Connect environment, the CNA is configured in Flex-10 mode to connect
virtualized server blades to data and storage networks. Each port is logically divided into as
many as four individual devices that share the total bandwidth of the network connection.
Bandwidth limits can be dynamically configured on each NIC. One of these individual devices
on each port can be an FCoE device. For more information about HP Virtual Connect, see
the following website:
http://h18004.www1.hp.com/products/blades/virtualconnect/index.html
•
In other environments, the CNA is configured as two individual devices per port, one FCoE
and one LAN device, depending on the hardware configuration, both sharing the bandwidth
of the network connection.
The CNA can be integrated into the highly-scalable HP FlexFabric data center architecture of an
HP Converged Infrastructure. This open architecture uses industry standards to simplify server and
storage network connections while providing seamless interoperability with existing core data
center networks.
On BL8x0c i4 server blade systems, CNA devices called “integrated FlexFabric adapters” are
embedded in the system board to provide more functionality and intelligence than do traditional
LAN-only LOM adapters. The integrated FlexFabric adapters support LAN and FCoE connectivity
concurrently with high-performance protocol offloads, optimizing server efficiency and maximizing
server virtualization ratios. Connectivity can be fully virtualized to support traditional management,
virtual machine migration, IP, NAS, iSCSI, and FCoE protocols, all on a single network.

Combo overview
A 10GbE/Fibre Channel combo adapter card is a PCIe adapter that HP-UX configures as four
separate devices — a dual port FC device and a dual port LAN device. The FC devices are
connected to an FC fabric through two FC fiber connections on the adapter. The LAN devices are
connected to a 10Gigabit LAN through two NIC fiber connections on the adapter. The FC and
LAN devices do not share bandwidth on a common connection to the fabric or network.
Features
The iocxgbe driver is a PCIe 10 Gigabit Ethernet driver that can support the standup, mezzanine,
and LAN on motherboard (LOM) technologies for a variety of platforms. It can be integrated into
the highly-scalable HP FlexFabric data center architecture of an HP Converged Infrastructure.
The iocxgbe driver supports the HP Virtual Connect Flex-10 interface on server blade platforms
to connect server blades to data and storage networks. By allowing you to logically divide each
network port into multiple devices, the HP Virtual Connect Flex-10 technology reduces management
requirements, the number of NICs and interconnect modules needed, and power and operational
costs. Before HP Virtual Connect was introduced, only two interconnect choices were available for
connecting server blades to a network — passthrough devices and switches. Passthrough devices
