The Cisco UCS VIC 1240 is a modular LAN-on-motherboard (mLOM) adapter designed for the M3 generation of Cisco UCS B-Series Blade Servers. It provides four 10-Gigabit Ethernet ports with Fibre Channel over Ethernet (FCoE) capabilities. The VIC 1240 supports a stateless, agile infrastructure that can present up to 256 PCIe-compliant interfaces to the host, dynamically configured as network interface cards (NICs) or host bus adapters (HBAs). It also integrates Cisco's Data Center VM-FEX technology, extending the UCS fabric interconnects directly to virtual machines, simplifying virtualization and improving manageability.


The Cisco VIC 1240 supports bandwidth scaling through the use of a Port Expander card. When this expander is added, the VIC 1240's capabilities grow from four to eight 10-Gigabit Ethernet ports, effectively doubling the throughput available to the server. This allows administrators to adapt to increasing data demands without replacing the core adapter, maintaining a flexible and cost-efficient network infrastructure.

Base Standard Capabilities

FeatureBenefit
x16 PCIe generation-2 interfacesDelivers greater throughput
4 x 10-Gbps unified I/ODelivers 40 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
Up to 8 x 10-Gbps unified I/ODelivers 80 Gbps to the server when used with optional Port Expander
Up to 256 dynamic virtual adapters and interfacesCreates 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
Note: Cisco UCS VIC hardware is SR-IOV capable, and you can enable SR-IOV after SR-IOV is broadly supported by the popular operating systems. Please refer to UCS Manager configuration limits for your specific OS and environment in the configuration guide.
Cisco SingleConnect technologyA single unified network - the same network brings LAN, SAN, and management connectivity to each server
Cisco Data Center VM-FEX technology
  • 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
  • Provides a prestandard implementation of the IEEE 802.1BR Port Extender standard
Centralized managementEnables the mezzanine card to be centrally managed and configured by Cisco UCS Manager
Network architectureProvides a redundant path to the fabric interconnect using hardware-based fabric failover
More than 900,000 I/O operations per second (IOPS)Provides high I/O performance for demanding applications
Support for lossless EthernetUses Priority Flow Control (PFC) to enable FCoE as part of the Cisco unified fabric
Broad OS and hypervisor supportSupports customer requirements for Microsoft Windows, Red Hat Enterprise Linux, SUSE Linux, VMware vSphere and Citrix XenServer
