思科UCSM VM-FEX安装配置手册
思科UCSM VM-FEX安装配置手册Cisco UCS针对虚拟化环境的网络管理提供了两种解决方案：一种是纯软件的Cisco Nexus 1000V；一种是基于Cisco UCS VIC (Virtual Interface Card)网卡的硬件解决方案。
Cisco Nexus 1000V是唯一的第三方分布式虚拟交换机，同样实现了交换机的数据功能和控制功能的分离。
基于硬件的解决方案服务器需要配置Cisco UCS VIC卡。
这块卡的虚拟化功能非常强大。
本文简要介绍一下Cisco UCS基于硬件的虚拟化网络管理解决方案的配置过程。
配置动态UCS vNIC登录到UCS Manager，进入服务器配置管理选项卡，选择某个Service Profile的vNIC配置，如图1所示，在Actions中选择“Change Dynamic vNIC Connection Policy”。
图1. 在UCSM中更改动态vNIC连接策略如图2所示，在弹出的“Change Dynamic vNIC Connection Policy”对话框中设置Dynamic vNIC的数量为53并选择适配器策略为VMwarePassThru。
图2. 设置动态vNIC数量以及适配器策略需要说明的是，每片UCS 刀片服务器的Cisco UCS VIC网卡能够虚拟的网卡和HBA卡数量总和为：vHBAs+vNICs+Dynamic vNICs=（15*n）-2 ，其中n为上联链路数量。
在我们的实验环境中，有4条上联链路，虚拟的vHBA卡为2块，vNIC为3块，所以能够虚拟的Dynamic vNIC数量为15*4-2-2-3=53。
利用Cisco UCS VIC网卡创建的vHBA、vNIC如图3所示。
图3. 在UCSM中创建的vHBA、动态vNIC、静态vNIC信息下表说明了在使用VMware平台时，不同连接情况下Cisco UCS VIC 可以支持的vHBA、动态vNIC、静态vNIC数量。

思科统一计算系统（Cisco UCS）容量规划和系统更新操作说明书
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.

Cisco UCS Combines Blade and Rack Servers, Networking, and Storage Resources in a Distributed, Virtual Blade Chassis with a Single, Redundant Point of Connectivity and ManagementAmericas Headquarters Cisco Systems, Inc.

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.。

文档适用人员本文档资料主要面向负责铁姆肯虚拟化平台UCS服务器实施项目的设计和实施的技术人员，管理人员。
实施原则➢实施步骤的完整性，对于每一个实施步骤各方所需要执行的动作有明确的规定，有精确的时间顺序安排，对每一个动作有详细的操作步骤，对每一个执行的动作都有相应的检查是否完成的步骤，达到任何一个只要具有实际实施经验的工程师都能按实施方案完成执行动作。
➢详细描述实施方案的风险和局限性，明确使用实施方案所应承担的风险和将导致的后果。
➢在实施前需要各参与单位和人员最终确认实施方案的正确性、明确各方所执行的动作和担负的责任。
➢对于检查实施方案的每一个阶段是否达到方案要求，需要有每一阶段的测试内容，明确那些测试在指定时间点不能完成或完成后测试结果不正确的情况下需要采用网络回退方案，不再执行实施方案的下一个执行动作或不进入下一个实施阶段。
➢为了尽量减少业务中断时间，所有测试和改造工作都在重要业务停止时进行，同时对于参与测试的设备原有数据都要备份。
➢网络调整、应用切换方案在制定时要和所相关应用部门进行充分的沟通，要向应用部门介绍详细的切换过程，切换步骤、切换时间要征得相关应用部门的同意。
➢网络调整、应用切换实施时要有应用部门的人员在场，负责对应用进行验证，并得出结论。
