However, traditionaldata centers typically use inflexible, three-tier network designs that cannotefficiently manage east-west traffic or deliver the bandwidth neededto support virtualization and new service delivery. In addition, with thegrowth in cloud computing, a scalable, open, programmable, agile, andresponsive network infrastructure is essential.IT service delivery and data center operators need networks that are highperformance, operationally efficient, automated, and elastic. The idealnetwork also must be easy to manage and scale out to meet demandas well as adapt to future requirements.Optimizing Scale-outArchitectureBrocade VDX switches are designedto help organizations stay ahead ofapplication-driven network change byenabling agile growth through ascale-out architecture. This approachoffers three key benefits. First, it enablesnetwork expansion as a business growsover time. One can horizontally scalespine switches as the number of leafswitches increase. Second, scale-outarchitecture also enables the creationof resilient network fabrics, eliminatinga single point of failure and potentialdowntime. Third, and most important,a scale-out network architecturedelivers a compelling economic benefit.Unlike scale-up, a scale-out modellowers upfront investment. And by usinghigh-density fixed switches, it lowers theTotal Cost of Ownership (TCO), reducingpower, cooling, and data center space.Brocade VCS Fabric technologywas designed from the ground up tofacilitate and optimize these scale-outarchitectures. With zero-touch capabilities,scale-out is simple. Organizations canadd, move, or remove network resourceswithout changing configurations to theexisting network. Resiliency is baked intothe VCS fabric at every layer. And byemploying multipathing at Layers 1, 2,and 3, the VCS fabric eliminates anysingle point of failure.
Integrated resiliency: Multipathing atLayers 1, 2, and 3 provides resiliency atevery network layer.CoreCoreEthernet Fabric ArchitectureEdgeautomation (zero-touch provisioning,self-forming trunks, logical chassis)enables administrators to add, move,and delete capacity automatically.Aggregation Zero-touch scale-out: VCS fabricClassic Hierarchical Ethernet ArchitectureScalabilityAccessWHY CHOOSE BROCADEVCS FABRICS TO OPTIMIZESCALE-OUT ARCHITECTURE Simplified operation: VCS fabrics offera single point of management.

It offers 3640 GbE QSFP ports and can bedeployed as a spine or leaf switch.Each 40 GbE port can be broken out intofour independent 10 GbE SFP ports,providing a total of 144 10 GbE SFP .Deployed as a spine, it provides options toconnect either 40 GbE or 10 GbE uplinksfrom leaf switches. By deploying this highdensity, compact switch, administratorscan reduce their TCO through savings onpower, space, and cooling.ExternalInternetIn a leaf deployment, 10 GbE and40 GbE ports can be mixed, offeringflexible design options to cost-effectivelysupport demanding data center andservice provider environments. As in otherBrocade VDX platforms, the BrocadeVDX 6940-36Q offers a Ports onDemand (PoD) licensing model. BrocadeVDX 6940-36Q is available with 24 portsor 36 ports. The 24-port model offersa lower entry point for organizations thatwant to start small and grow their networksover time. By installing a software license,organizations can upgrade their 24-portswitch to the maximum 36-port switch.MPLSCloudDC Border/CoreL3SpineSwitchesL2Brocade VDX 6940Brocade VDX 6940LeafSwitchesFigure 2: The Brocade VDX 6940-36Q Switch in spine and leaf architectures.2
The Brocade VDX 6940-144S is a10 GbE optimized switch with 40 GbEor 100 GbE uplinks in a 2U form factor.It offers 96 native 1/10 GbE SFP/SFP ports and 12 40 GbE QSFP ports, or 4100 GbE QSFP28 ports. In addition,the Brocade VDX 6940-144S providesflexibility for uplinks, 40 GbE or 100 GbEfrom leaf switches, and delivers greatercross-sectional bandwidth for east-westtraffic. Purpose-built for scale-out datacenters and service providers, it enablesaggregation of multiple server racks with asingle switch.With its high density, the Brocade VDX6940-144S is an ideal fit for middle-of-rowor end-of-row data center deployments.By connecting multiple racks to a singlecut-through switch, this architecture offersgreater cross-sectional bandwidth forapplications. Servers from multiple rackscan be just one hop away from one another.The compact 2U form factor saves space,also reducing power and cooling, resultingin lower TCO for organizations.For both the Brocade VDX 6940-36Qand 6940-144S, front access ports arepositioned to enable easy server or switchconnectivity and to simplify cabling. With achoice of front-to-back or back-tofront airflow, these switches are idealfor deployments connecting servers,storage, and other switches, as well asfor providing compatibility for eitherhot aisle or cold aisle data center designs.For the 40 GbE ports that also support10 GbE connections with breakout cables,the switches offer the flexibility neededto support a mixed environment as datacenters or service providers transition tohigher bandwidth.ExternalInternetMPLSCloudDC Border/CoreSpineSwitchesL3L2Brocade VDX 6940 orBrocade VDX 8770LeafSwitchesUp to 8 racks with a pair of Brocade VDX 6940-144S SwitchesFigure 3: The Brocade VDX 6940-144S Switch for middle-of-row architecture.Cloud and Big Data EnvironmentsBrocade VDX 6940 Switches deliveroptimized buffer and latency and highperformance to enable greater crosssectional bandwidth for east-west traffic—exactly what cloud workloads demand.These switches offer the flexibility neededto scale-out networks, deliver intelligenceto more effectively manage VM mobility,as well as provide an SDN-enabled andprogrammable infrastructure. BrocadeVDX 6940 Switches also offer anadvanced feature set that non-virtualand Big Data environments require.With 10/40/100 GbE options fordesigning oversubscribed or nonoversubscribed networks, highthroughput, and optimized buffer andlatency, it is an ideal switch for Big Dataapplications. Together with Brocade VCSFabric technology, Brocade VDX 6940Switches can simplify network design andoperations for both cloud and Big Datanetwork fabrics.High Performance for DataCentersAs data centers virtualize more of theirservers and VM density per serverincreases, organizations will requirehigher bandwidth connectivity to supportthe explosion of data and applicationprocessing. With 40 GbE and 10GbE options, Brocade VDX 6940Switches deliver the high-performancecomputing needed to keep up with thedemands of a virtualized data center,allowing organizations to reducenetwork congestion, improve applicationperformance, and meet the capacityrequired by 10 GbE servers. The 40GbE uplinks can easily aggregate highbandwidth traffic and reduce bottlenecksthat occur when aggregating multiple 10GbE connections, keeping data centernetworks working at peak performance.Brocade VDX 6940 Switches also helpmaximize network utilization with hardwarebased Brocade ISL Trunking. Organizationscan create a 120 GbE Brocade ISL trunk byutilizing three 40 GbE ports. The BrocadeISL trunk is automatically formed betweentwo Brocade VDX 6940 Switches whenthey are linked together, allowing traffic tobe equally distributed among all ports.This increases link efficiency and limitstraffic disruptions, especially during hightraffic times.3
Dedicated Networks for IPStorageBuilding a dedicated network for IPstorage is considered a best practiceamong today’s enterprises. This approachto IP storage networks helps ensureindependent administrative control andoperation, as well as a tight couplingof the application, compute, storage,and network. It allows enterprises toeffectively and reliably support evergrowing applications and workloadswhile improving service-level guarantees,containing failure domains, and reducingsecurity risks.Whether building a next-generationstorage network for server virtualization,business applications, replication, orbackup and recovery, organizationsneed a solution that not only performs,but also provides high availability, faulttolerance, and the ability to expandover time. Brocade VDX switchesdeliver that performance, resiliency, andscale via patented load balancing andmultipathing—cutting-edge technologiesleveraged from a long heritage ofBrocade Fibre Channel solutions. Selfprovisioning and self-healing, BrocadeVDX switches offer unmatched simplicityand automation, minimizing the learningcurve and ongoing operational costsfor storage administrators. BrocadeVDX 6940 Switches can facilitate anoptimal IP storage network by deliveringa fabric-based network architectureto manage the network and storageholistically. At the same time, BrocadeNetwork Advisor provides organizationswith unified management, networkvisibility, and insight across all of theirstorage networks, including dedicated IPstorage networks.4Optimized Packet Bufferand Latency for BetterApplication PerformanceBrocade VDX 6940 Switches offer aunique balance between two conflictingattributes—-buffer and latency. Nicheproducts with very high buffer often sufferfrom high latency, and products withultra-low latency are not a good fit fordata centers with bursty traffic. BrocadeVDX 6940 Switches, with a purpose-builtdata center chip, excel in optimizing bufferand latency to deliver better applicationperformance. These switches deliver700 ns any-port-to-any-port latency. Inaddition, they offer an industry-leading24 MB deep buffer. This provides thebuffering capacity to handle increases intraffic, especially during peak times whenports are congested, allowing traffic to bedistributed across the ports. Brocade VDX6940 Switches also feature a single ASICdesign, instead of multiple ASIC designscommonly found in other switches. Thisimproves performance since all portscommunicate via the one ASIC.Brocade VCX Fabric TechnologyBrocade VCS fabrics running on theBrocade VDX family of switches alloworganizations to create data centernetworks that just work. Together,these technologies provide unmatchedautomation, efficiency, and elasticityin support of the most demandingworkloads, such as rich media andmission-critical applications, particularlyin highly dynamic cloud environments.To learn more about Brocade VCS Fabrictechnology, visit www.brocade.com/vcs.Unmatched Simplicityand AutomationBrocade VDX 6940 Switches, inconjunction with Brocade VCS Fabrictechnology, streamline configurationand management, maximize efficiency,and create a more automated andreliable network, especially in highlyvirtualized environments. Brocade VCSFabric technology delivers unmatchedautomation, efficiency, and resiliencecompared to traditional architectures andcompetitive fabric offerings. It delivershigher throughput and lower latencyfor the server-to-server (east-west)traffic patterns that are now dominatingvirtualized data centers. In changinghow networks are architected,VCS fabrics deliver many benefits thatfit the needs of evolving environments.Fast, Easy Deploymentand ConfigurationBrocade VCS Fabric technology helpsstreamline network operations and speeddeployment with embedded featuresthat enable automatic configuration andmanagement. These features include: Brocade VCS Logical Chassis:Brocade VCS Logical Chassis enablesorganizations to manage an entireVCS fabric as a single switch, upgradesoftware across the fabric with onecommand, and centralize monitoringand troubleshooting to enhance theoverall availability and reliability of thenetwork. Fabric-level REST APIs allowhigher-level management frameworksto provide efficient orchestration ofVCS fabrics within a cloud context.
The single point of managementeliminates the need to manuallyconfigure and manage each switch,simplifying management, loweringoperational costs, and reducingconfiguration errors with the abilityto push software upgrades acrossthe fabric with a single command,accelerating deployment. VCS LogicalChassis also provides a single viewof the fabric for easy monitoring andtroubleshooting, minimizing the timeto repair network issues. For moreinformation about VCS Logical Chassis,read the white paper An Overview ofBrocade VCS Logical Chassis. Self-forming and self-healing fabric:Configuration is simplified with selfforming fabrics. As additional switchesare added, they inherit the configurationof the fabric, allowing the network toscale out with ease. Configuration anddevice information is always sharedamong all Brocade VDX switches,allowing fabric nodes to be addedor removed, and physical or virtualservers to be relocated—without thefabric requiring manual reconfiguration.In addition, fabrics are self-healing,increasing network resiliency. Thefabric redirects traffic in case a link fails,helping to ensure uninterrupted trafficflow and prevent data loss. Zero-touch provisioning andzero-touch scale-out: Zero-touchprovisioning enables simple, rapiddeployment. Provided natively inBrocade VDX switches throughVCS Fabric technology, this featureenables installation, automatic softwaredownload, and configuration withoutuser intervention.Brocade VDX switches arepreconfigured so that newly deployedswitches require only power and anetwork connection to become partof the fabric. RBridge-ID, VCS-ID,and other VCS fabric parameters areautomatically assigned. In addition,Inter-Switch Links (ISLs) automaticallyform between all new and existingswitches in the fabric. By eliminatingmanual processes, this installationmethod greatly simplifies scale-outarchitecture.Zero-touch provisioning facilitateszero-touch scale-out. With automaticconfiguration of VCS fabric parameters,self-forming trunks, and logical chassis,network engineers can add, move, andremove network Brocade VDX switcheswithout having to add or delete networkconfigurations. This helps organizationscontain costs while increasing reliabilityand speed when deploying clouds anddata centers. A reliable foundation for software-defined networks: The Brocade VDX6940 is hardware-enabled with theflexibility to support emerging SDNprotocols, including VXLAN/NVGRE.VCS Logical Chassis technology andnorthbound APIs with fabric- andnode-level orchestration capabilitiesprovide operationally scalablemanagement and integration with datacenter orchestration frameworks suchas OpenStack. For more information,read the white paper Brocade VCSFabrics: The Foundation for SoftwareDefined Networks.In-Service Software UpgradesThe Brocade VDX 6940 delivers a highlyefficient In-Service Software Upgrade(ISSU) by leveraging a software modelthat uses a dual-OS infrastructure on amulti-core CPU. This enables data centeradministrators to deliver enterprise-classbusiness continuity on fixed switchesduring a software upgrade/downgradeprocess. This software change process isnon-disruptive to Layer 2, Layer 3, FibreChannel, and Fibre Channel over Ethernet(FCoE) traffic. Moreover, the ISSUimplementation is hardware-optimized,thus reducing the time it takes to completethe upgrade/downgrade process.Maximum Efficiency andResiliencyBrocade VCS Fabric technology createsa more efficient and resilient networkwith a flat-meshed Layer 2 topologythat delivers the high performance andhigh reliability required by data centers.Organizations gain a more flexiblenetwork that helps them rapidly adaptto changing business conditions andtraffic patterns.Optimized East-West TrafficTraditional data centers are architectedwith a rigid, three-tier tree topologyoptimized for the north-south traffic flowof client-server computing environments,compromising performance, increasinglatency, and creating bottlenecks. Withthe increased prevalence of virtualizationand distributed applications, data centernetwork traffic is now predominantly eastwest or server-server. The VCS fabric wasspecifically designed and optimized toaddress these traffic patterns by movingtraffic through any of the active paths andavoiding the multiple hops required inother tiered topologies.5

Traditional VLANs canbe used for this purpose up to a point,but limitations on VLAN ID scale and thecomplexity of configuring large numbersof VLANs restrict their usefulness inlarger data centers. The VCS VirtualFabric feature of Brocade VCS Fabrictechnology is designed to address thescalability restrictions of traditional VLANsused for multitenant segmentation.It provides native secure multitenantsupport for both physical and virtualapplication deployments within and acrossVCS fabrics. Managed centrally throughBrocade VCS Logical Chassis, the VCSVirtual Fabric feature simplifies andaccelerates application deployment, andensures policy consistency for each tenant6Layer 2 traffic across multiple virtualfabrics within a single data center, oracross multiple data centers, while stillmaintaining multitenant segmentation.Moreover, they can avoid installingcostly dedicated WAN links or MPLS/GRE underlay, as virtual fabric extensionrequires only simple Layer 3IP connectivity across sites.regardless of how application componentsare distributed across the data center.VXLAN and VRF Lite are other optionsfor network segmentation. To learn more,read Multitenancy Options in BrocadeVCS Fabrics.Virtual Fabric ExtensionVirtual fabric extension permits a Layer2 connection between multiple VCSfabrics interconnected over a Layer3 cloud. This allows VLANs, serviceVLANs, and transport VLANs to spanacross multiple VCS fabrics.Virtual fabric extension is achievedthrough VXLAN encapsulation of Layer2 frames, which are tunneled across VCSfabrics over a Layer 3 cloud. This featuredoes not require NSX or multicast to berunning in Layer 3 clouds interconnectingVCS fabrics and any other controller.With virtual fabric extension, serviceproviders and enterprises can extendBrocade VCS Fabric technology enableshighly elastic domains with extremelyefficient load balancing in Layers 1–3.Innovative Brocade ISL Trunking loadbalances traffic across all the links ina trunk for improved performance atLayer 1. In Layer 2, Equal Cost MultiPath (ECMP) uses all available networkbandwidth, allowing all links to be fullyactive and utilized. In the event of a failure,traffic is automatically routed to theclosest path, providing higher resilienceand greater application uptime. In Layer3, the fabric automatically load balancesall flows among a number of Layer 3instances that collectively act as a singleLayer 3 gateway. Multilayer multipathinghelps improve network utilization, reducelatency, and increase overall networkperformance.

By
unifying the best of both worlds—physical and virtual—Brocade VCSGateway for NSX allows physicaldevices to connect to virtual devices.Brocade VCS Gateway is integratedwith VMware NSX, enabling the entireVCS fabric to function as a VXLANgateway and eliminating the needfor specific network placement. Assuch, the NSX Controller sees theVCS fabric as a single logical gateway,thereby simplifying management andproviding resiliency. Administratorscan leverage existing infrastructurewhile gaining the benefits of VXLAN tosupport multitenancy and large-scaledeployments of distributed applications.In addition, Brocade VCS Gateway forNSX is integrated with the VMwareNSX Controller. It offers the benefits ofagility with self-service provisioning,flexible network architecture, scale-outmodularity with VCS fabric, multitenancy,and an easily managed unified solutionfor physical and virtual assets. Zero-touch VM discovery: BrocadeVM-Aware Network Automationeliminates the manual configurationof port profiles when a VM is addedto the fabric or moved, providing anadditional level of automation. TheVCS fabric directly communicateswith VMware vCenter, automaticallydownloading all port profile informationand the associated MAC address, anddistributes the VM-specific informationto all switches within the fabric.When the VM moves, no additionalconfiguration is required. Automatic Migration of PortProfiles: During a VM migration, thedestination network switch ports mustbe configured to ensure that the VMtraffic experiences consistent policiesand configurations. With the BrocadeAutomatic Migration of Port Profiles(AMPP) feature, the VM policies andnetworking policies follow the VM withinthe VCS fabric. As a VM migrates,the destination port in the fabriclearns of the MAC address move andautomatically activates the port profileconfiguration within a single fabricor across separate fabrics. AMPP ishypervisor-agnostic and can be usedwith various hypervisors.Flexible Design Meets DataCenter NeedsBrocade VDX 6940 Switches aredesigned to connect data centers inmultiple ways to meet individual designrequirements. This flexible designprovides investment protection, givingorganizations a single switch that cansupport varying data center requirements.The following features help organizationsmeet their evolving needs: 10/40/100 GbE uplinks: The 40 GbEQSFP ports offer the flexibility toexpand and interconnect the networkinfrastructure intelligently and efficientlywhile reducing bottlenecks. The switchesoffer the option to separate each40 GbE uplink into four 10 GbE uplinksvia breakout cables. As capacity andneed increase, organizations can simplyrevert to 40 GbE when ready. Ports on Demand: Ports on Demand(PoD) enables organizations to activate12 additional ports. They can purchasethe number of ports that they currentlyneed and seamlessly scale up later bysimply applying a software license.This flexible and cost-efficient “payas-you-grow” licensing model solvesscalability challenges by allocating ITresources as needed.Advanced Storage SupportBrocade VDX 6940 Switches provideadvanced storage support with multiplestorage connectivity options, includingFCoE, iSCSI, and NAS. They also featureData Center Bridging (DCB), whichenables the reliable exchange of storagetraffic over the LAN, eliminating packetloss when network congestion occursand allocating bandwidth as needed tokeep the network running efficiently.The switches offer NAS Auto QoSintelligence to prioritize delay-sensitiveIP storage traffic within the fabric andhelp ensure consistent performancewhile decreasing latency.Ease-of-Use Augmented byBrocade Network AdvisorBrocade Network Advisor is an easyto-use network management platformfor advanced management of BrocadeVCS fabrics and Brocade VDX switchesacross the entire network lifecycle.Organizations can use Brocade NetworkAdvisor to manage a VCS fabric as asingle entity or to drill down to individualBrocade VDX switches for fault, inventory,or performance management—and tomanage multiple VCS fabrics in parallel.Brocade Network Advisor also providessimplified management of AMPPconfigurations, and integrity checks canbe performed across physical BrocadeVDX configurations—either in the samefabric or across different VCS fabrics.In addition, Brocade Network Advisorenables VM-level monitoring and can helpidentify top-talker applications leveragingsFlow across the fabric.
