Additional Information
Cisco UCS Virtual Interface Card 1225 Data Sheet (Cisco)

A Cisco® innovation, the Cisco UCS Virtual Interface Card (VIC) 1225 (Figure 1) is a dual-port Enhanced Small Form-Factor Pluggable (SFP+) 10 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE)-capable PCI Express (PCIe) card designed exclusively for Cisco UCS C-Series Rack Servers. With its half-height design, the card preserves full-height slots in servers for third-party adapters certified by Cisco. 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 1225 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
Feature Benefit
x16 PCIe generation-2 interfaces Delivers greater throughput
2 x 10-Gbps unified I/O
  • Delivers 20 Gbps to the server
  • Helps reduce TCO by consolidating the overall number of NICs, HBAs, cables, and switches because LAN and SAN traffic run over the same adapter card and fabric
Up to 256 dynamic virtual adapters and interfaces
  • 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

Note: Cisco UCS VIC 1225 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 technology

A 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 in a single infrastructure
  • Provides virtual machine visibility from the physical network and a consistent network operating model for physical and virtual servers
  • Enables configurations and policies to follow the virtual machine during virtual machine migration
  • Provides a pre-standard implementation of the IEEE 802.1BR Port Extender standard

Centralized management

Enables the card to be centrally managed and configured by Cisco UCS Manager

Network architecture

Provides a redundant path to the fabric interconnect using hardware-based fabric failover

More than 600,000 I/O operations per second (IOPS)

Provides high I/O performance for demanding applications

Support for lossless Ethernet

Uses Priority Flow Control (PFC) to enable FCoE as part of the Cisco unified fabric

Broad OS and hypervisor support

Supports customer requirements for Microsoft Windows, Red Hat Enterprise Linux, SUSE Linux, VMware vSphere, and Citrix XenServer
