Cisco UCS M81KR Virtual Interface Card 

 

The Cisco Unified Computing System

™

 is a next-generation data center platform that unites compute, network, 

storage access, and virtualization into a cohesive system designed to reduce total cost of ownership (TCO) and 

increase business agility. The system integrates a low-latency, lossless 10 Gigabit Ethernet unified network fabric 

with enterprise-class, x86-architecture servers. The system is an integrated, scalable, multichassis platform in which 

all resources participate in a unified management domain. 

A Cisco

®

 innovation, the Cisco UCS M81KR Virtual Interface Card (VIC) is a virtualization-optimized Fibre Channel 

over Ethernet (FCoE) mezzanine card designed for use with Cisco UCS B-Series Blade Servers (Figure 1). The VIC 

is a dual-port 10 Gigabit Ethernet mezzanine card that supports up to 128 Peripheral Component Interconnect 

Express (PCIe) standards-compliant virtual interfaces that can be dynamically configured so that both their interface 

type (network interface card [NIC] or host bus adapter [HBA]) and identity (MAC address and worldwide name 

[WWN]) are established using just-in-time provisioning. In addition, the Cisco UCS M81KR supports Cisco VN-Link 

technology, which adds server-virtualization intelligence to the network.

Unique to the Cisco Unified Computing System, the Cisco UCS M81KR is designed for both traditional operating 

system and virtualized environments. It is optimized for virtualized environments, for organizations that seek 

increased mobility in their physical environments, and for data centers that want to reduce TCO through NIC, HBA, 

cabling, and switch reduction. 

The Cisco UCS M81KR presents up to 128 virtual interfaces to the operating system on a given blade. The virtual 

interfaces can be dynamically configured by Cisco UCS Manager as either Fibre Channel or Ethernet devices 

(Figure 2). To an operating system or a hypervisor running on a Cisco UCS B-Series Blade Server, the virtual
