1.Cisco UCS 6100系列互联阵列（Fabric Interconnect）：是思科统一计算系统的核心组成部分，提供线速、低延时、无丢包10Gbps以太网和FCoE（以太网光纤通道）统一通信给UCS 5100 系列刀片机箱和机箱里面的B系列刀片服务器。
所有连接到Cisco UCS 6100 Fabric Interconnect 的机箱和刀片服务器，将组成一个统一高可用的管理域，并输出10G网络流量给上层的网络交换机（比如，思科的Catalyst 6500系列）和4G的光纤流量给上层的存储交换机（比如，思科的MDS 9000系列）。
6100系列是在Nexus 5000交换机的基础上开发，但是两者之间有明显差异。
6100系列除了提供强大的通信能力之外，还内嵌了可管理这个UCS的系统管理程序（Manager），具体细节请查看下段。
6100系列现有两个型号可供选择：一个是提供20个端口的6120XP，另一个则是提供40个端口的6140XP。
评论：首先，由于UCS系统通过Fabric Interconnect来统一所有的通信，无论是以太网流量，光纤流量，机箱内部的刀片之间的流量，还是刀片上面的虚拟机之间流量，所以使得网络方面的管理得以简化，而且使用的cable数量非常少，这将降低安装和维护的复杂度。
其次，这个Fabric Interconnect可扩展性极强，它能支持40个刀片机箱，总共多达320台刀片。
最后，因为UCS自带的刀片服务器和刀片机箱不包含存储设备，所以企业需要自备存储，并将其连到和Fabric Interconnect相连的存储交换机上。
2.UCS 管理程序（Manager）：能为UCS系统创建和管理一个统一的域，可被视为UCS的中枢系统，提供图形界面（GUI）、命令行（CLI）和XML API 这三大接口。
直观的GUI模式是采用类似于Java Applet技术，在浏览器上运行的Java应用，它主要有四个特点：1. 它将整个UCS系统作为一个统一的域来管理。
Capacity planning and system refresh Highlightsoperations are inseparable in data centers.optimum approach ties capacity expansion to the regular server refresh cycle,enabling IT to plan for demand and gain computing power in an intelligent manner.addition, built-in management functions provide exceptional visibility into and control over the entire infrastructureto streamline and coordinate administrative effort and eliminate common errors that delay deployment and disrupt operation.that supports blade and rack-mountservers to deliver scalability andperformance. A unified fabric supportedby a single, distributed virtual switchinterconnects all server resources.Servers and virtual machines areinterconnected equally and consistently,eliminating multiple layers of switching.This radically simplified architecturepacks more computing power intoless space while allowing IT to choosefrom a portfolio of servers to delivermassive computing density andcreates barriers to resource sharing and requires additional dedicated servers standing by to take over work in the event of a failure. Cisco UCS eliminates architectural silos through on-demand provisioning. Any computing resource potentially can be used for any application at any time. The infrastructure is “wire once” with all configuration managed through Cisco UCS Manager, eliminating the physical barriers that used to prevent applications from sharing resources.The intelligent infrastructure providedby Cisco UCS enables the entireconfiguration to be programmedthrough the intuitive Cisco UCSManager GUI and open standard XMLAPI. While other vendors supportthe automatic configuration of a fewparameters, Cisco UCS Managerincludes nearly 100 server identityparameters, eliminating the needfor manual tasks or the creationof scripts or the use of tools andagents that further complicate the ITenvironment. With Cisco UCS Manager,IT organizations can plan capacity on aholistic, data center wide basis, sharinginfrastructure across applications andharnessing it to best meet businesspriorities and service-level agreements(SLAs).Eliminating Networkand Cable Sprawl andComplexityUsing traditional implementations, theconnection of servers and storagesystems to growing numbers of userapplications and services requires extensive networking infrastructure. The resulting dramatically increased connectivity uses massive numbersof cables, creating significant management challenges. Administrators find it difficult to locate ports for new servers, to map and zone connectivity, and to track and locate sourcesof failures. In addition, this cable proliferation and sprawl requires vast numbers of switch ports and switches, which consume power and increase management complexity.Simplified Network Infrastructure Addressing the increasing need for better design and control, Cisco UCS provides greater network density with less cabling and complexity. Cisco’s unified fabric integrates Cisco UCS servers with a single high-bandwidth, low-latency network that supportsall system I/O. This fabric carries IP, storage, and management traffic over redundant 10 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE) networks. This approach simplifies the architecture and reduces the number of I/O interfaces, cables, and access-layer switch ports that are required for traditional platforms. This unification can reduce network complexity by up to a factor of three, and the system’s wire-once network infrastructure increases agility and accelerates deployment with zero-touch configuration.All I/O traffic meets at a single specific and redundant point at which it is efficiently and consistently managed, increasing network security, simplifying management, and reducing errors. This approach eliminates blade-server and hypervisor-resident switching, condensing three network layersinto one and reducing capital andoperating costs. With the capability tointerconnect physical servers and virtualmachines as functional equivalents,the architecture delivers outstandingvisibility and control that lets virtualnetworks be managed with the samelevel of control as physical networks.Simplifying and AcceleratingServer Refresh OperationsThe ad hoc approach to expansionused in many data centers makes itdifficult to refresh and consolidate theenvironment. Cumbersome processesthat are tied to a complicated physicaland virtual infrastructure hamper IT’sability to install and configure newsystems and to rehost virtual serversand applications. Administrators mustperform tedious, repetitive, and time-consuming tasks that are often thesource of errors or result in inconsistentconfigurations or application ofcorporate policies and security. Thesedelays and inconsistencies affectapplication and service redeploymentand keep the IT organization fromsupporting real-time business needsand priorities.Automated Configuration for FastDeploymentCisco UCS simplifies and acceleratesserver refresh operations throughautomated configuration. The intelligentinfrastructure abstracts server identity,personality, and I/O connectivityfrom the hardware, enabling thesecharacteristics to be applied ondemand. Every aspect of a server’sconfiguration, from firmware revisionsand BIOS settings to network profiles,can be assigned through the system’sopen, documented, standards-basedXML API or Cisco UCS Manager GUI.As a result, server configurations canbe replicated easily. A new server canappear to the software stack just likethe old server, making server refreshoperations as simple as applying aCisco service profile and rebooting tolaunch the new system.Service Profiles Support PrestagingCisco service profile templatesestablish policy-based configurationfor server, network, and storageresources and can be used to logicallypreconfigure these resources evenbefore they are deployed in the datacenter. By preparing service profiles inadvance, administrators can prestageIP addresses and storage world-widenames (WWNs) and attach mappingsto components. In addition, CiscoUCS blade server slots can be set toautomatically configure blade serversupon insertion with network andstorage settings that are in compliancewith the policies established byappropriate data center administrators.Configuration also can be performed asa manual process as needed, with fullserver identity parameter control andintegration with network and storageresources.Making Virtualization MoreEffectiveAs data centers reach the limits oftheir physical capacity, virtualizationstrategies to consolidate workloadsonto fewer resources can be importantaids. Yet the virtualization effortsdeployed by many data centers haveresulted in new challenges. The useof blade server chassis-resident networks and hypervisor-resident software switches creates a complex set of switching layers that makes managing, debugging, and securing virtual networks difficult. Server sprawl continues unabated, with a proliferation of physical servers added to the environment to support a vast arrayof virtual machines, delivering ever-increasing numbers of applications and services. With a patchworkof technologies in place, physicaland virtual systems are deployed, connected, and managed in many different ways, further complicating infrastructure administration and management.More Virtualization at Less Cost Cisco UCS enables IT organizations to meet ever-increasing guest operating system memory footprint demands on fewer physical servers. The system’s high density, high-performance design,including Cisco Extended MemoryTechnology, increases consolidationratios for 2-socket servers, saving thecapital, operating, physical space, andlicensing costs of running virtualizationsoftware on larger, 4-socket servers.With support for up to 1 terabyte(TB) of high-speed memory in a2-socket server, organizations canhost applications using less-expensiveservers without sacrificing performance.As a result, IT organizations can putmore virtual machines on each server,reducing physical server sprawl andbreaking down management silos.Greater Visibility and ControlIT organizations need to simplifyphysical infrastructure to break downsilos and make the data center moreeffective. They also need to improvetheir virtual infrastructure so that it canbe managed just as simply and easilyas it scales. Traditional virtualizedenvironments require the use ofsoftware-based switches that reside inthe hypervisor. The insertion of a newswitch can cause a loss of visibility fromthe physical network interface to virtualmachines. The result is a network ofvirtual machines with connection pointsthat cannot be seen. If connectionscannot be seen, they cannot bemanaged or secured.Cisco UCS uses virtualization-optimizednetworking that makes managingvirtual machine networks equivalentto managing physical networks.Cisco FEX Technology architectureextends the visibility of network andstorage access all the way to individualvirtual machines, without hypervisorintervention. These connectionsterminate in the fabric interconnects asvirtual ports that are managed exactlythe same way as physical ports.

To view a list of Cisco trademarks, go to this network interface cards (vNICs) are attached to virtual machines, and their network profiles remain constant and attached, even when virtual machines are moved from one physical server to a different server, enhancing mobility and security. Workloads can bemigrated between physical devices, optimizing performance and maintaining security protocols and policies, without requiring intervention by the network team to reset quality of service (QoS) and security for each migrated virtual machine.The Cisco UCS design results in a distributed, virtual blade chassis that combines the performance and management of physical networks with the scalability of virtual networks. Administrators can use familiar management models on virtualmachines and take advantage of built-in automation and intelligence to gain outstanding visibility into, and control over, virtualized environments. Forexample, bandwidth can be flexibly and dynamically managed with a QoS policy to help guarantee bandwidth for priority workloads running in virtual machines, while also helping ensure that overall bandwidth is used efficiently and not wasted (Figure 2).More Capacity and Reduced ComplexityData center infrastructure management has become a complicated challenge. The proliferation of management points and the physical devices to which they are connected has resulted in a new kind of sprawl that must be contained. Typically, administrators have to use a variety of element managers to interact with dozens of management touch points that are distributedacross multiple servers, blade chassis, racks, networking, and storageresources. Unfortunately, most vendors attempt to solve this management challenge by introducing additional layers of management tools that are patched together into an accidental architecture that creates more work for administrators.Less Complex and Easier to Manage The unified infrastructure andarchitecture-by-design approach of Cisco UCS delivers the scalability needed to perform capacity planning and refresh activities without the complexity of traditional systems. The dramatic reduction in the number of physical components results in a system that makes effective use of limited space, power, and cooling by deploying less infrastructure to perform the same, or even more, work.The system’s unified fabric results in fewer NICs, host bus adapters (HBAs), cables, and upstream switch ports, and eliminates the need for a parallel Fibre Channel end-to-end network. Traditional blade server chassis resident switches are replaced by a low-cost, low-power, zero-management fabric extender that enables the entire system to scale across multiple blade chassis and rack servers without addingmanagement points. All hardware and software components are managed through the unified, embedded Cisco UCS Manager to improve operation efficiency with seamless scaling.ConclusionDeployment of Cisco UCS systems enables data centers to reap the benefits of a simplified infrastructure. By consolidating from a large-footprint rack or complex and network-intensive blade environment to Cisco UCS, IT organizations can reduce the footprint and complexity of the entire datacenter. Server refresh and consolidationoperations become easy, scalable, and repeatable exercises that optimize data center investments.Learn MoreTo learn more about Cisco UCS, visit /go/ucs or contact your local account representative.。

思科UCS：真正意义上的系统创新 思科通过真正意义上的系统架构探索服务器之外的技术世界內容提要当下的客户需求许多企业正逐渐意识到他们的 IT 部门正在为满足企业数字化转型而提出的新需求而绞尽脑汁。
然而，其中许多企业的IT部门仍然禁锢于采用 “竖井”和分立元件搭建起来的网络环境，而不是经过深思熟虑和周密考量后搭建真正适合自己的系统基础架构。
如果 IT 部门的领导们下决心对其基础架构进行现代化改造，他们所需要的解决方案不仅需要足够灵活和敏捷，还要让 IT 团队继续掌握对整个基础架构的可视性和控制性。
思科统一计算系统（Cisco UCS）平台就是这样一种统一的、系统层级的解决方案，它通过整合大量基于策略的可编程基础架构为企业的各种工作负载和 IT 运作模式提供有效支持。
面对瞬息万变的需求，企业不得不考虑用一些新的方法来代替传统的 IT 解决方案。
这是因为当下竞争激烈的市场对基础架构的敏捷性和灵活性提出了越来越高的要求，尤其是数据中心，对云经济的需求与日俱增。
尽管如此，许多企业仍然继续采购传统的服务器，并采用针对特定应用程序和用例推出的单点产品解决方案。
虽然服务器市场的年营业额呈现持续下降的趋势，但通用的机架式服务器仍然占据市场主导地位。
此外，加之服务器平均售工作负载要求的瞬息万变则让情况变得更加具有挑战性。
但是随着这类要求的不断演变， IT 部门如果把主要精力放在成本约束上，其创新能力就会受到限制。
然而想单纯依靠削减成本来帮助企业改善业务成效，效果其实并不理想。
IT 部门所采用的传统方案已经不再适合企业当下所需要的更加灵活、不断变换的环境。
企业目前所需要的，则是能让 IT 部门从现有技术局限性中解脱出来，并从真正意义上实现创新的系统。
在当今世界，随着混合式 IT 的日益发展，企业需要通过构建一个整体架构，将非本地公有云的速度和简洁与本地云的可视性和控制性有机结合在一起。
但是如果不涉及到失控或放弃当前的部分能力，那么敏捷性始终是最关键的。
