1 Privae Cloud Compuing for Enerprises: Mee he Demands of High Uilizaion and Rapid Change Wha You Will Learn Enerprise daa ceners are faced wih a criical challenge: The number of applicaions and amoun of daa in he daa cener coninue heir rapid growh, while IT sruggles o provide he resources necessary o make services available o users and mee oday s demands using exising infrasrucure and organizaional silos. For oo long, his siloed approach has hindered IT from adjusing dynamically o new business requess. In exising silos, applicaion workloads are ighly coupled o physical asses, wih sofware linked o operaing sysems o manage availabiliy, enforce securiy, and help ensure performance. This ighly coupled model has resuled in proliferaion of server and sorage devices, wih aendan coss and mainenance overhead, o mee user demand. Unforunaely, only a small porion of each dollar spen on IT oday creaes a direc business benefi. Cusomers are spending approximaely 70 percen of heir budges on operaions, and only 30 percen on differeniaing he business. Since daa cener IT asses become obsolee approximaely every 5 years, he vas majoriy of IT invesmen is spen on upgrading various pieces of infrasrucure and providing redundancy and recoverabiliy: aciviies ha consume approximaely 60 o 80 percen of IT expendiures wihou necessarily providing opimal business value or innovaion. In addiion, he reurn on invesmen (ROI) for new IT projecs can ake anywhere from 9 o 18 monhs. As a resul, IT has been forced o focus on simply keeping he daa cener running raher han on delivering he kind of innovaion ha mees user needs for faser, beer services while also meeing requiremens and ensuring business agiliy. Wha is needed is a soluion wih he scale, flexibiliy, and ransparency o enable IT o provision new services quickly and cos effecively by using service-level agreemens (SLAs) o address IT requiremens and policies, mee he demands of high uilizaion, and dynamically respond o change, in addiion o providing securiy and high performance. Cloud compuing provides a soluion for meeing his challenge, and using he Cisco porfolio of producs, enerprises can begin moving oward a cloud compuing soluion oday. The Enerprise Cloud Compuing Model Cloud compuing is being proposed as one answer o he challenges of IT silos inefficiencies, high coss, and ongoing suppor and mainenance concerns and increasing user demand for services. While ransacional daa and high-performance file share applicaions are bes handled now wihin enerprise daa ceners, cloud compuing is demonsraing is abiliy o handle he increasing Inerne daa from rich web applicaions, services from online service providers, large daa processing jobs, and digial media creaion wih follow-on global disribuion. In addiion, many indusry analyss and businesses agree on he cloud compuing opporuniy. In 2008, oal spending on cloud compuing services was esimaed o have a 27 percen compound annual growh rae (CAGR) beween 2008 and 2012, growing from US$16 billion o US$42 billion, according o IDC; cloud services are projeced o grow a 5 imes he rae of curren enerprise IT spending Cisco Sysems, Inc.

2 Barriers o Adopion of Cloud Compuing Model While cusomers agree abou he benefis of cloud compuing, hey have concerns abou cos and flexibiliy, in paricular abou securiy, compaibiliy wih exising applicaions, lack of a migraion pah from exising applicaions o clouds, freedom of choice, federaion of inernal and exernal resources, lack of SLAs for policy-based managemen, and ineroperabiliy. The good news is ha hese challenges can be resolved using a cloud compuing approach ha includes compuing, nework, virualizaion, and sorage resources. Cisco is faciliaing he firs sep for he enerprise oward a mulienan cloud compuing soluion wih a unique approach oward enerprise cloud compuing: privae clouds. Why Cloud Compuing? According o he Garner Group, cloud compuing is bes defined as an infrasrucure uiliy ha is open, flexible, predesigned and sandardized, virualized, and highly auomaed, as well as secure and reliable. Cisco refines his definiion, defining cloud compuing as a model ha provides resources and services ha are absraced from he underlying infrasrucure and provided on demand and a scale in a muli-enan environmen. In addiion o is on-demand qualiy and is scalabiliy, cloud compuing can provide he enerprise wih: Global disribuion capabiliies, wih policy-based conrol by geography and oher facors Operaional efficiency from consisen infrasrucure, policy-based auomaion, and rused muli-enan operaions Inegraed service managemen inerfaces naive o he cloud Regulaory compliance hrough auomaed daa policies Lower-cos compuing Many companies are rapidly evolving oward cloud compuing, hough from differen saring poins and no wihou debae as o he bes direcion or compuing model. For example, advocaes of public cloud compuing someimes advise no owning any sofware or hardware or employing any IT adminisraors and insead relying on professional providers of IT applicaions, plaforms, infrasrucure, and services. The original Wikipedia definiion of cloud compuing emphasized ha posiion: Cloud compuing is Inerne ( cloud ) based developmen and use of compuer echnology ( compuing ). I is a syle of compuing in which dynamically scalable and ofen virualized resources are provided as a service over he Inerne. Users need no have knowledge of, experise in, or conrol over he echnology infrasrucure in he cloud ha suppors hem. On he oher side of he debae are hose who have spen years building IT infrasrucures, whose concerns mus be addressed since reliabiliy, securiy, SLAs, and ineroperabiliy will deermine he success of he various cloud compuing models wihin he enerprise. Inernal Clouds Enerprises ha wan o ake full advanage of exising IT infrasrucure invesmens ofen sar wih an inernal cloud. An inernal cloud applies he conceps of cloud compuing (on-demand resources, pay-as-you-go pricing, and he appearance of infinie scalabiliy) o resources wholly owned by he enerprise consuming he service. By enhancing exising infrasrucure wih cloud compuing capabiliies, he inernal cloud can provide economies of scale and he abiliy o handle boh exising and new web-based applicaions, while providing securiy and regulaory compliance Cisco Sysems, Inc.

3 Exernal Clouds Today, well-known clouds are ypically associaed wih an off-premises, hosed model. These exernal, or public, clouds involve IT resources and services sold wih cloud compuing qualiies, such as self-service, pay-as-you-go billing, on-demand provisioning, and he appearance of infinie scalabiliy. They are accessed hrough web browsers or hrough APIs and offer nearly unlimied capaciy on demand a pay-per-use pricing, bu wih limied cusomer conrol. Some exernal cloud ypes include: Sofware as a service, in which applicaion services are delivered over he nework on a subscripion basis: for example, Salesforce.com Plaform as a service, in which sofware developmen frameworks and componens are delivered over he nework on a pay-as-you-go basis: for example, Google Apps Infrasrucure as a service, in which compuing, nework, and sorage services are delivered over he nework on a pay-as-you-go basis: for example, Amazon EC2 Alhough many hird-pary vendors of exernal clouds are experiencing increasing demand for heir offerings, businesses repor some concern regarding infrasrucures hosed by hird paries for mission-criical, highly confidenial applicaions. Businesses and enerprises require securiy, service-level guaranees, and compliance conrol, bu wih public clouds, he vendors are in conrol of hese requisie capabiliies. Evoluion Toward Privae Clouds In conras o exernal clouds, privae clouds enerprise IT infrasrucure services, managed by he business, wih cloud compuing qualiies such as self-service, pay-as-you-go charge-back, on-demand provisioning, and he appearance of infinie scalabiliy provide a criical benefi: rus. Iniially, mos privae clouds will be made up almos enirely of inernal resources. A privae cloud can combine boh exernal and inernal cloud resources o mee he needs of an applicaion sysem, and ha combinaion, which is oally under enerprise conrol using unified managemen, can change momen by momen. Wih a privae cloud, enerprises can run processes inernally and exernally, having esablished he privae cloud as he conrol poin for workloads. Wih conrol hrough a unified managemen ool and a user-cenric view, he privae cloud hus enables IT o make he bes decisions abou wheher o use inernal or exernal resources, or boh. and allows ha decision o be made on a real-ime basis o mee user service needs. Privae clouds should no be confused wih hybrid clouds. A hybrid cloud uses boh exernal (under he conrol of a vendor) and inernal (under he conrol of he enerprise) cloud capabiliies o mee he needs of an applicaion sysem. A privae cloud les he enerprise choose, and conrol he use of, boh ypes of resources Thus, privae clouds eliminae he rewrie everyhing effec of own nohing public cloud compuing. They also provide he rused conrol ha enerprises are seeking from inernal clouds, including he capabiliy o change he mix of cloud services o be consumed, as needed. Privae cloud compuing has he poenial o eliminae enerprise silos while reducing coss hrough economies of scale and allows businesses o exploi he new economics, wih faser deploymen of new business applicaions and capaciy for greaer agiliy. Mos imporan, privae cloud compuing offers a clear and logical pahway ha preserves exising invesmen in applicaions and informaion, while each sep delivers immediae value and builds a foundaion for he nex Cisco Sysems, Inc.

4 The Movemen Toward Privae Cloud Compuing Today he movemen oward privae clouds has sared, wih he virualized daa cener and virualized deskops. I involves hree sages, shown in Figure 1. Figure 1. The Enerprise Movemen Toward a Muli-Tenan Cloud Soluion Sage 1: Consolidaion and Virualizaion The movemen oward cloud compuing began for he enerprise wih daa cener virualizaion and consolidaion of server, sorage, and nework resources o reduce redundancy and wased space and equipmen wih measured planning of boh archiecure (including faciliies allocaion and design) and process. According o John Chambers, Cisco CEO, Plaform-based virualizaion wih a unified fabric will drive he globalizaion of IT resources cliens, servers, daa ceners, neworks, and sorage. Virualizaion echnologies enable he absracion and aggregaion of all daa cener resources in order o urn hem ino a unified logical resource ha can be shared by all applicaion loads. Virualizaion decouples he physical IT infrasrucure from he applicaions and services being hosed, allowing greaer efficiency and flexibiliy, wih any effec on sysem adminisraion produciviy handled by ools and processes. Consolidaion is a criical applicaion of virualizaion, enabling IT deparmens o regain conrol of disribued resources by creaing shared pools of sandardized resources ha can be raionalized and cenrally managed. Many IT deparmens already are consolidaing underuilized compuing resources by running muliple applicaions on a single physical server wih virualizaion echnology from VMware. The percenage of new servers running virualizaion as he primary boo opion will approach 90 percen by 2012, according o analyss. Many cusomers are using server virualizaion no only for server consolidaion, bu also o improve flexibiliy, speed up service provisioning, and reduce planned and unplanned downime. Enerprise IT also has underaken projecs o regain conrol of expanding sorage resources by consolidaing ino scalable SANs. And server virualizaion is jus he sar; virualizaion really needs o exend o nework and sorage. Virualizaion of servers, sorage, and neworks will enable he mobiliy of applicaions and daa no only across servers and sorage 2009 Cisco Sysems, Inc. All righs reserved.

5 arrays in he same daa cener which cusomers are already implemening in producion bu also across daa ceners and neworks. Afer cusomers sar virualizing and aggregaing resources ino a single pool, hey can operae more efficienly, flexibly, and reliably. Alhough he mos immediae moivaions for server, sorage, and nework virualizaion are improved resource uilizaion and lower capial and operaing coss, he ulimae goal is he use of he absracion beween applicaions and infrasrucure o manage IT as a service. Enerprises ha wan o begin moving oward cloud compuing can sar wih inernal, self-buil clouds, uilizing virualizaion for consolidaion and auomaion. Sage 2: Auomaion and Opimized Virualizaion In he second sage, enerprises need o move from managing underlying infrasrucure o managing service levels based on wha makes sense for he user of applicaions. For example, he cusomer may wan o manage facors such as he minimum olerable applicaion laency or he availabiliy level of an applicaion. Enerprises also mus implemen auomaion for cenral IT and self-service for end users, hus exricaing IT from he business of repeiive managemen procedures and enabling end users o ge wha hey need quickly. In his sage, virualizaion opimizes IT resources and increases IT agiliy, hus speeding ime-o-marke for services. The IT infrasrucure undergoes a ransformaion in which i becomes auomaed and criical IT processes are dynamic and conrolled by rused policies. Through auomaion, daa ceners sysemaically remove manual labor requiremens for he run-ime operaion of he daa cener. Provisioning auomaion is he bes-known and mos-ofen implemened form of auomaion. Sophisicaed auomaion can help reduce operaing expenses hrough: On-demand reallocaion of compuing resources Run-ime response o capaciy demands Trouble-icke response auomaion (or eliminaion of rouble ickes for mos auomaed response scenarios) Inegraed sysem managemen and measuremen The ulimae goal, however, is alignmen of operaions wih business needs hrough creaion of a uiliy compuing model. To creae a cloud service, self-service and meering (feedback abou he cos of he resources allocaed) are offered in addiion o auomaion. Wih self-service and meering, he compuing model resembles a uiliy. The privae cloud hen is a echnical sraegy o urn compuing power ino uiliy compuing, wih he daa and coss conrolled and managed by he enerprise. Self-service and meering are breakhrough capabiliies for end users and business unis, faciliaing managemen and exension of he user experience. Now here is no inermediary beween he consumer of a resource and he processes for he acquisiion and allocaion of resources for core businesses requiremens and iniiaives. Since he consumer iniiaes he service requess, now IT is an on-demand service raher han a gaekeeper. Wih he ransiion o an on-demand service, he cos srucure is dramaically reduced, since he user uses and pays for only wha is needed a a specific momen. The business benefi of his change in cos srucure is significan. For example, wih he hardware and provisioning freedom ha comes wih a privae cloud, a major pharmaceuical company can perform muliple drug rials ha cos 2009 Cisco Sysems, Inc. All righs reserved.

7 While self-service and meering are breakhrough privae cloud capabiliies for end users and business unis, mainaining service delivery in a fully virualized muli-enancy environmen and providing securiy, especially for informaion and services leaving he daa cener environmen, are essenial enerprise requiremens for IT adminisraors Wih a privae cloud uiliy model enabling hese needs and requiremens, enerprises can scale and expand by pooling IT resources in a single cloud operaing sysem or managemen plaform. They hen can suppor anywhere from ens o housands of applicaions and services and enable new archiecures argeing very large-scale compuing aciviies. Sage 3: Federaion Creaion of an open, compeiive markeplace, in which IT capabiliies in a uiliy model can be procured, allocaed, and provisioned over he Inerne on demand by he consumer, wih self-service and meering, requires federaion. Federaion linking disparae cloud compuing infrasrucures wih one anoher by connecing heir individual managemen infrasrucures allows disparae cloud IT resources and capabiliies capaciy, monioring, and managemen o be shared, much like power from a power grid. I also enables unified meering and billing, onesop self-service provisioning, and he movemen of applicaion loads beween clouds, since federaion can occur across daa cener and organizaion boundaries, wih cloud inerneworking. Cloud inerneworking is he nework echnology enabling he linkage of disparae cloud sysems in a way ha accommodaes he unique naure of cloud compuing and he running of IT workloads. Service Providers and Virual Privae Clouds To go beyond organizaional boundaries hrough cloud inerneworking o reach a hird-pary, businesses will need service providers and virual privae cloud services. Ulimaely, service providers will offer boh public and virual privae cloud services on a secure infrasrucure, and ha will allow enerprises o include and consume hose services as par of enerprise privae clouds, wihou exposing conen o he general public. This virual privae cloud service provider model would: Enable choice hrough open inercloud sandards and services Suppor federaion across inernal and exernal clouds Deliver cloud services wih securiy, qualiy of service (QoS), and manageabiliy Use sandards for consolidaed applicaion and service managemen and billing Thus, enerprises will be able o choose freely among he service providers, and service providers will be able o use oher providers infrasrucures ha allow federaion o handle excepional loads on heir own offerings. Wih virualizaion of he privae cloud, Cisco will offer soluions ha suppor he packaging of applicaions and daa and he linkages beween hem ino virual conainers. The virual conainer, a sandards-based represenaion of he virual infrasrucure and relaed policies, can be inerpreed and implemened as a physical infrasrucure. Virual privae clouds will exend he rus benefi of he privae cloud o include hird-pary componens and service provider services Cisco Sysems, Inc. All righs reserved.

8 Why Use Privae Clouds? The privae cloud is a new syle of compuing in which corporae IT infrasrucure is available as a ubiquious, easily accessible, and reliable uiliy service. Business owners and applicaion owners requesing a new business service can use he infrasrucure as a sandard service, wihou he need o undersand he complexiies of servers, sorage, and neworks. The privae cloud brings he benefis of cloud compuing under he conrol of corporae IT: Available on demand Faser provisioning of business services Reduced cos hrough economies of scale Flexibiliy and freedom of choice o run workload and applicaions in he mos efficien and effecive places Use-based, pay-as-you-go model Sandardized, audiable service levels Capabiliy o work wih every applicaion, boh curren and fuure, wihou he need o rewrie applicaions Secure and conrolled by corporae IT Privae clouds serve many ypes of users in a variey of business seings: corporae and division offices, business parners, raw-maerial suppliers, resellers, disribuors, and producion and supply-chain eniies. Building he Privae Cloud While mos cusomers have some undersanding of he benefis of IT as a service and he privae cloud model, many cusomers do no know how o build a privae cloud. Today, Cisco is building core elemens of a virualized and cohesive sysem, inegraing deskop sysems, mobile devices, daa ceners, servers, neworks, and sorage resources hrough open sandards, in secure and rused, muli-enan enerprise soluions, saring wih privae clouds (Figure 2).

9 Cisco Virualized Nework Plaform Cloud compuing and privae clouds operae a he inersecion of compuing, neworking, and virualizaion, as shown in he Cisco Unified Compuing Sysem (Figure 3). Figure 3. Cisco Unified Compuing Sysem From Cisco s perspecive, he nework is he foundaion for cloud inerneworking, wih he capabiliy o deliver: Neworking echnologies o make he cloud enerprise-ready Nework inelligence for workload porabiliy Mulimedia (video) delivery in he cloud Ineroperabiliy across clouds User experience wih end-o-end service delivery across clouds As a saring poin, exising producs in he Cisco Daa Cener 3.0 and Cisco Unified Compuing Sysem porfolios enable he enerprise o ransiion o he cloud. The underlying enes of he Cisco Daa Cener 3.0 and Cisco Unified Compuing Sysem porfolios are consolidaion, virualizaion, and auomaion: he same enes ha underpin cloud compuing. These echnologies are crucial enablers of cloud compuing infrasrucures. Wih hese echnologies, and in an evoluionary manner, cusomers can creae dynamic virualized infrasrucures ha will ake advanage of new privae cloud soluions from Cisco during he coming year. Server Consolidaion The firs sep oward reducing oal cos of ownership (TCO) in he enerprise daa cener is server consolidaion. Daa ceners oday, wih heir siloed environmens and high coss, are characerized by fewer han approximaely 15 percen of producion workloads running on virual machines. As more cusomers ry o reduce coss using server virualizaion echnologies such as VMware vsphere he firs cloud operaing sysem o ransform IT infrasrucures ino privae clouds he virual machine will become he defaul applicaion plaform, wih 60 o 80 percen of x86 applicaions running in a virualized environmen Cisco Sysems, Inc.

10 Transiion o 10 Gigabi Eherne From a neworking perspecive, he increase in virual machine densiy encourages a ransiion o 10 Gigabi Eherne as he defaul mechanism for aaching servers. Muliple virual machines on a single server can quickly overwhelm a single Gigabi Eherne link, and muliple Gigabi Eherne links can increase coss. The Cisco Nexus Family, including he Cisco Nexus 7000 Series Swiches and Cisco Nexus 2000 Series Fabric Exenders, suppors exising Gigabi Eherne aached servers in oday s daa ceners and enables fuure deploymen of 10 Gigabi Eherne, unified fabric, and virual machine aware neworking (wih Cisco VN-Link). Cisco Nexus 1000V Series Swiches provide operaional consisency down o he individual virual machine as well as policy porabiliy, so nework and securiy policy follows virual machines as hey move around he daa cener. The Cisco Nexus 1000V Series can be deployed wherever VMware ESX is currenly running, wihou dependencies based on he server uplink speed or upsream access swich. Consolidaion of Server I/O To coninue o reduce TCO and o deploy virual machines wih echnologies like VMware Disribued Resource Scheduling (DRS), all servers mus have a consisen and ubiquious se of nework and sorage capabiliies. One of he simples and mos efficien ways o deliver hese capabiliies is o deploy a unified fabric. The shif o a unified fabric gives all servers, physical and virual, access o he SAN, allowing more sorage o be consolidaed in he cusomer s SAN for greaer efficiency and coss savings. Unified Fabric To consolidae server I/O, he server access layer mus be adaped o suppor a unified fabric. Cisco Nexus Family producs enable his suppor, since hey suppor Fibre Channel over Eherne (FCoE), Small Compuer Sysem Inerface over IP (iscsi), and Fibre Channel. On he nework side, supporing FCoE is simply a maer of enabling FCoE feaures in he Cisco Nexus 5000 Series Swiches and insalling eiher he Fibre Channel or Fibre Channel and Daa Cener Bridging (DCB) uplink modules. Any aached Cisco Nexus 2000 Series Fabric Exenders inheri FCoE capabiliy. The Cisco Nexus 7000 Series is FCoE capable; DCB-capable I/O modules (o provide reliable ranspor) will be available Deploymen of FCoE on he server side requires eiher a new converged nework adaper (CNA) from a company such as Emulex or QLogic or, in he case of Inel inerfaces, a new sofware driver for he 10 Gigabi Eherne nework adapors. FCoE is suppored on VMware vsphere, and he Emulex, Inel, and QLogic inerfaces are on he VMware ESX 3.5 hardware compaibiliy lis (HCL), so his sep encompasses boh physical and virual servers. Scalable, Dynamic, Unified Fabric Wih a scalable, dynamic, unified fabric, now any daa cener asse can access any oher asse. From a sorage perspecive, he Cisco daa cener fabric will suppor FCoE and iscsi server access and FCoE, Fibre Channel, and iscsi aached arges. DCB will expand from he access layer ino he aggregaion and core layers, simplifying access o he Fibre Channel SAN. FCoE inerfaces o he exising Cisco MDS 9000 Family of direcor-class Fibre Channel swiches will simplify access o he exising SAN. Unified Compuing The unified fabric now enables a fully virualized daa cener composed of pools of compuing, nework, and sorage resources. Services such as securiy and Layer 4 hrough 7 processing (for example, load balancing) are virualized and can be implemened whenever hey are needed, along wih auomaed managemen and provisioning capabiliies. In addiion, Cisco VN-Link nework services are available in VMware vsphere environmens wih he Cisco Nexus 1000V Series Swiches and hrough he Cisco Unified Compuing Sysem. Cisco VN-Link sorage services are available as par of he inelligen fabric delivered by he Cisco MDS 9000 Family of mulilayer SAN swiches Cisco Sysems, Inc. All righs reserved.

11 Cisco VN-Link bridges he server, sorage, and nework managemen domains, so changes in one environmen are communicaed o he ohers. Cisco VN-Link helps enable new capabiliies and feaures, simplifies managemen and operaions, and allows scaling for server virualizaion soluions. Specific benefis include: Real-ime policy-based configuraion Mobile securiy and nework policy, moving policy wih he virual machine during VMware VMoion live migraion for persisen nework, securiy, and sorage compliance Nondisrupive managemen model, aligning managemen and operaions environmen for virual machines and physical server conneciviy in he daa cener The daa cener up o his poin in is evoluion has been confined o he enerprise. The Cisco Unified Compuing Sysem faciliaes movemen ouside he enerprise for services. The Cisco Unified Compuing Sysem bridges he silos in he daa cener, enabling beer uilizaion of IT infrasrucure in a fully virualized environmen, and creaes a unified archiecure using indusry-sandard echnologies ha provide ineroperabiliy and invesmen proecion. The archiecure unies compuing, nework, sorage access, and virualizaion resources ino a scalable, modular design ha is managed as a single energy-efficien sysem hrough Cisco UCS Manager, managemen sofware embedded in he Cisco UCS 6100 Series Fabric Inerconnecs, a family of line-rae, low-laency, lossless, 10-Gbps Cisco DCB and FCoE inerconnec swiches ha consolidae I/O wihin he sysem. Cisco UCS Manager provides an inuiive GUI, a command-line inerface (CLI), and a robus API for managing all sysem configuraion and operaion. Cisco UCS Manager helps increase IT saff produciviy, enabling IT managers of sorage, neworking, compuing, and applicaions o collaborae on defining service profiles for applicaions. Service profiles help auomae provisioning, allowing daa cener managers o provision applicaions in minues insead of days. The Cisco Unified Compuing Sysem provides suppor for a unified fabric over a low-laency, lossless, 10-Gbps Eherne foundaion. This nework foundaion consolidaes oday s separae neworks: LANs, SANs, and highperformance compuing neworks. Nework consolidaion lowers coss by reducing he number of nework adapers, swiches, and cables and hus decreasing power and cooling requiremens. The Cisco Unified Compuing Sysem also allows consolidaed access o boh SANs and nework aached sorage (NAS). Wih is unified fabric, he Cisco Unified Compuing Sysem can access sorage over Eherne, Fibre Channel, FCoE, and iscsi, providing cusomers wih choices and invesmen proecion. In addiion, IT saff can preassign sorage access policies for sysem conneciviy o sorage resources, simplifying sorage conneciviy and managemen. Cisco UCS 2100 Series Fabric Exenders bring unified fabric o he Cisco UCS 5100 Series Blade Server Chassis, providing up o four 10-Gbps connecions each beween blade servers and he fabric inerconnec, simplifying diagnosics, cabling, and managemen. The new Cisco UCS B-Series Blade Servers, based on he fuure Inel Nehalem processor families (he nexgeneraion Inel Xeon processor), offer paened exended memory echnology o suppor applicaions wih large daa ses and allow significanly more virual machines per server. Cisco UCS B-Series Blade Servers suppor up o eigh blade servers and up o wo fabric exenders in a six-rack-uni (6RU) enclosure, wihou he need for addiional managemen modules. Each blade server uses nework adapers for access o he unified fabric. Cisco UCS nework adapers include adapers opimized for virualizaion, compaibiliy wih exising driver sacks, and efficien, high-performance Eherne. Wih inegraed managemen and wire-once unified fabric wih he indusry-sandard compuing plaform, he Cisco Unified Compuing Sysem opimizes virualizaion, provides 2009 Cisco Sysems, Inc.
