Converged Network Adapters

Table 86

describes available Brocade Converged Network Adapters (CNAs) for PCIe x 8 host bus

interfaces, hereafter referred to as Brocade CNAs. These adapters provide reliable,
high-performance host connectivity for mission-critical SAN environments.

Brocade CNAs combine the functions of a Host Bus Adapter (HBA) and Network Interface Card
(NIC) on one PCIe x 8 card. The CNAs appear as NICs and Fibre Channel adapters to the host.
These CNAs fully support FCoE protocols and allow Fibre Channel traffic to converge onto 10 Gbps
Data Center Bridging (DCB) networks. FCoE and 10 Gbps DCB operations are simultaneous.

The combined high performance and proven reliability of a single-ASIC design makes these CNAs
ideal for connecting host systems on Ethernet networks to SAN fabrics based on Brocade Fabric or
M-Enterprise operating systems.

Fabric Adapters

Table 87

describes the available Brocade 1860 Fabric Adapter model. The Brocade 1860 provides

dual mode support for the port. You can configure the port mode as a 16 Gbps Fibre Channel (FC)
HBA and a 10 Gbps CNA mode using the Brocade Command Utility (BCU).

The Brocade 1741M-k and Brocade 1007 are two-port 10 GbE CNAs that mount on a blade server that installs in

a system enclosure. The adapter uses FCoE to converge standard data and storage networking data onto a shared
Ethernet link. Ethernet and Fibre Channel communication are routed through the DCB ports on the adapter to the
blade system enclosure midplane and onto the installed switch modules installed in the enclosure.

The Brocade 1741M-k and Brocade 1007 CNAs connect to the embedded switch modules or embedded

interconnect modules on the blade system chassis by way of an internal backplane and, therefore, no optical
modules (SFP transceivers) are involved. With the exception of no SFP transceivers, the Brocade 1741M-k and
Brocade 1007 CNAs function the same as the other Brocade CNAs.

For information on installing the Brocade CNAs on a blade server, refer to the Brocade Adapters Installation and
Reference Guide
