Cisco Unified Computing System Overview

The Cisco Unified Computing System (Cisco UCS) is a next-generation data center platform that unites compute, network, storage access, and virtualization resources 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.

Product Overview

A Cisco® innovation, the Cisco UCS Virtual Interface Card (VIC) 1280 (Figure 1) is an eight-port 10 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE)-capable mezzanine card designed exclusively for Cisco UCS B‑Series Blade Servers. 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 1280 supports Cisco 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).

Network Interface Virtualization: Each PCIe interface created on the VIC is associated with an interface on the Cisco UCS Fabric Interconnect, providing complete network separation for each virtual cable between a PCIe device on the VIC and the interface on the Cisco UCS Fabric Interconnect.

Cisco SingleConnect Technology

Cisco® SingleConnect technology provides an exceptionally easy, intelligent, and efficient way to connect and manage computing in the data center. Cisco SingleConnect technology is an exclusive Cisco innovation that dramatically simplifies the way that data centers connect to:

    Rack and blade servers

    Physical servers and virtual machines

    LAN, SAN, and management networks

The solution addresses the challenges of today’s data center, and the result is a simple, intelligent, and efficient fabric:

    Easy: Cisco SingleConnect technology provides a “wire once and walk away” solution that eliminates traditional manual, time-consuming, error-prone processes and instead makes connecting servers to the Cisco Unified Computing System (Cisco UCS®) fast and easy.

    Intelligent: the technology is intelligent because it uses a zero-touch model to allocate I/O connectivity (LAN, SAN, and management) across any type of server: physical rack and blade servers and virtual machines. The network intelligence helps Cisco UCS adapt to the needs of applications. Rather than limiting applications to specific servers, Cisco UCS makes it easy to run any workload on any server.

    Efficient: the technology is highly efficient because LAN, SAN, and management connections are shared over a single network, increasing utilization while reducing the number of moving parts compared to traditional approaches with multiple networks.

Cisco SingleConnect technology is implemented with an end-to-end system I/O architecture that uses Cisco Unified Fabric and Cisco Fabric Extender Technology (FEX Technology) to connect every Cisco UCS component with a single network and a single network layer. As customers expect from Cisco, the Cisco UCS I/O architecture is based on open standards and is reliable, available, and secure.

Cisco VM-FEX Technology

Cisco VM-FEX technology extends Fabric Interconnect ports directly to virtual machines, eliminating software‑based switching in the hypervisor. Cisco VM-FEX technology collapses virtual and physical networking infrastructure into a single infrastructure that is fully aware of the virtual machines’ locations and networking policies (Figure 3). Cisco FEX-VM technology is implemented by Cisco VICs with a pre-standard implementation of IEEE 802.1BR Port Extender.

Table 1 summarizes the features and benefits of the Cisco UCS VIC 1280.

Table 1.         Features and Benefits



x16 PCIe Gen2 interfaces

Delivers greater throughput

8 x 10-Gbps unified I/O

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 run over the same mezzanine 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 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 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 management

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

Network architecture

Provides 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 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
