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).

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 fabric interconnect (Figure 3).

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 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 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 highly reliable, available, and secure.

Cisco Data Center VM-FEX technology

Cisco Data Center VM-FEX technology extends fabric interconnect ports directly to virtual machines, eliminating software-based switching in the hypervisor. Cisco Data Center 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 4). Cisco Data Center VM-FEX technology is implemented by Cisco VICs with a prestandard implementation of IEEE 802.1BR Port Extender.

Table 1 summarizes the main features and benefits of the Cisco UCS VIC 1227.

Table 1.           Features and benefits

Feature

Benefit

x8 PCIe Gen2 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 1227 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 Cisco UCS Manager configuration limits for your specific OS and environment in the configuration guide.
