Product Details

The Cisco UCS Virtual Interface Card (VIC) 1340 is a 2-port 40-Gbps Ethernet or dual 4 x 10-Gbps Ethernet, Fibre Channel over Ethernet (FCoE)-capable modular LAN on motherboard (mLOM) designed exclusively for the M4 generation of Cisco UCS B-Series Blade Servers. When used in combination with an optional port expander, the Cisco UCS VIC 1340 capabilities is enabled for two ports of 40-Gbps Ethernet.

The Cisco UCS VIC 1340 enables a policy-based, stateless, agile server infrastructure that can present over 256 PCIe standards-compliant interfaces to the host that can be dynamically configured as either network interface cards (NICs) or host bus adapters (HBAs). In addition, the Cisco UCS VIC 1340 supports Cisco® Data Center Virtual Machine Fabric Extender (VM-FEX) technology, which extends the Cisco UCS fabric interconnect ports to virtual machines, simplifying server virtualization deployment and management.


  • Delivers greater throughput
  • Delivers 80 Gbps to the server
  • Helps reduce TCO by consolidating the overall number of NICs, HBAs, cables, and switches because LAN and SAN traffic runs over the same mezzanine card and fabric
  • Adapts to either 10-Gbps or 40-Gbps fabric connections
  • Creates fully functional unique and independent PCIe adapters and interfaces (NICs or HBAs) without requiring single-root I/O virtualization (SR-IOV) support from OSs or hypervisors
  • Allows these virtual interfaces and adapters to be configured and operated independently, just like physical interfaces and adapters
  • Creates a highly flexible I/O environment needing only one card for all I/O configurations
  • A single unified network: the same network brings LAN, SAN, and management connectivity to each server
  • Unifies virtual and physical networking into a single infrastructure
  • Provides virtual machine visibility from the physical network and a consistent network operations model for physical and virtual servers
  • Enables configurations and policies to follow the virtual machine during virtual machine migration
  • Enables the mezzanine card to be centrally managed and configured by Cisco UCS Manager
  • Provides a redundant path to the fabric interconnect using hardware-based fabric failover
  • Provides high I/O performance for demanding applications
  • Uses Priority Flow Control (PFC) to enable FCoE as part of the Cisco unified fabric
  • Supports customer requirements for Microsoft Windows, Red Hat Enterprise Linux, CentOS and Ubuntu, and Citrix Hypervisor, formerly XenServer
