Cisco UCS Virtual Interface Cards
The Cisco UCS VIC 1340 is a 2-port, 40 Gigabit Ethernet, FCoE-capable modular
LAN on motherboard (mLOM) mezzanine adapter. Designed exclusively for Cisco
UCS B200 M3 and M4 Blade Servers, the Cisco UCS VIC 1340 provides 10-, 20-,
or 40-Gbps unified fabric access directly to the blade server, depending on how the
VIC is configured and the fabric extender to which it is connected.

VIC is configured and the fabric extender to which it is connected.
The personality of the card is determined dynamically at boot time using the service
profile associated with the server. The number, type (NIC or HBA), identity (MAC
address and World Wide Name [WWN]), failover policy, bandwidth, and QoS policies
of the PCIe interfaces are all determined using the service profile. The capability to
define, create, and use interfaces on demand provides a stateless and agile server
infrastructure.

The ways that interfaces are defined on the Cisco UCS VIC 1340 depends on
several factors, including whether a port expander is installed and the chosen Cisco
UCS fabric extender, as described in the sections that follow.

Cisco UCS VIC 1340 Connectivity to Cisco UCS 2200 Series Fabric Extender
The Cisco UCS VIC 1340 can be connected to a Cisco UCS 2200 Series Fabric
Extender either by itself or with a port expander inserted in the blade server’s
mezzanine connector. By itself, the Cisco UCS VIC 1340 provides four 10-Gbps
interfaces, combined by port channels into two 20-Gbps interfaces, with one
connected to each fabric (Figure 7).

If you add a mezzanine-based port expander to the blade server, the Cisco UCS
VIC 1340 provides two 40-Gbps interfaces: one to each fabric. However, the
interfaces are still four 10-Gbps interfaces combined in a port channel, and not true
40-Gbps interfaces (Figure 8).
