Cisco UCS Virtual Interface Card 1227
Cisco Unified Computing System Overview
The Cisco Unified Computing System
™
(Cisco UCS
®
) is a next-generation data center platform that unites
computing, networking, storage access, and virtualization resources in a cohesive system designed to reduce total
cost of ownership (TCO) and increase business agility. The system integrates a low-latency, lossless 10-Gbps
Ethernet unified network fabric with enterprise-class blade and rack x86-architecture servers. The system is an
integrated, scalable, multichassis platform in which all resources participate in a unified management domain.
Product Overview
The Cisco UCS Virtual Interface Card (VIC) 1227 is a dual-port Enhanced Small Form-Factor Pluggable (SFP+)
10-Gbps Ethernet and Fibre Channel over Ethernet (FCoE)-capable PCI Express (PCIe) modular LAN-on-
motherboard (mLOM) adapter designed exclusively for Cisco UCS C-Series Rack Servers (Figure 1). New to Cisco
rack servers, the mLOM slot can be used to install a Cisco VIC without consuming a PCIe slot, which provides
greater I/O expandability. It incorporates next-generation converged network adapter (CNA) technology from Cisco,
providing investment protection for future feature releases. The card enables a policy-based, stateless, agile server
infrastructure that can present up to 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
1227 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.

Features and Benefits
Stateless and Agile
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 quality-of-service (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
(Figure 2).
