PRODUCT OVERVIEWVxRack System1000 SeriesRackVXRACK SYSTEM 1000WITH FLEX NODESVCE has expanded the industry’s broadest converged infrastructure system portfolioto include rack-scale hyper-converged systems. The VxRack System 1000 series is aVCE engineered and manufactured product family with industry-best life cyclemanagement and assurance, adding rack-scale capabilities to complement VCEVblock Systems and VxBlock Systems. In addition, the VxRack 1000 connectsthrough VCE Vscale Architecture, enabling additional Enterprise and Service Provideruse cases and consumption models.Only VCE provides standardization, modular scale, tightly integrated convergedsolutions, life cycle management, and industry-best customer experience—enablingon-demand IT services that further accelerate business outcomes and time-to-value.Hyper-converged Software-defined StorageVCE VxRack System 1000 with FLEX Nodes is engineered by VCE and based onEMC ScaleIO technology. Easy to deploy. All-inclusivesolution including networking. Flexible consumption model.Rapidly deploy applications throughintegrated hyper-convergedsystem. Grow-as-you-need. Start smallwith a single rack and grow to datacenter scale. Asymmetric scale. Flexibly addcompute and storage capabilities. No more silos. Dissolve datacenter silos through anarchitecture that accommodatesboth traditional converged andhyper-converged environments.VxRack with FLEX Nodes virtualizes the server’s direct-attached storage (DAS) into ashared, network-based, block storage solution that is similar to SAN storage, yet issoftware defined. This makes it easy to achieve extreme scale—up to thousands ofnodes. As part of the VCE VxRack System 1000 series family, it is the only hyperconverged infrastructures that provides extreme scale. And VxRack with FLEX Nodesachieves this without compromising data center performance, high availability,resiliency, or security.Start Small and Grow to Web-scaleVxRack with FLEX Nodes enables scale-out capabilities to your data center. Start smallwith as little as four nodes and grow to web scale. Add nodes one by one within asingle rack or scale out with additional racks as compute and storage resources areconsumed. This provides your infrastructure with elastic sizing and efficient scalability,allowing you to start small with your proof of concept or new application and grow toweb-scale size as your requirements evolve. Simplified operations withunified UI. Manage through astandard framework that providesa comprehensive systems and datacenter view of infrastructure. VCE Experience. VxRack Systems are pre-built, pre-tested,and receive pre-validation on newfirmware/and software releases(Release Certification Matrix). 2016 VCE COMPANY, LLC. ALL RIGHTS RESERVED.VCE CONFIDENTIAL

NetworkingThe significance ofnetworking at scale Plan for growth—Expand yourenvironment easily without theworry of complicated networkcalculations. Integrate networking—Networking isa critical part of the hyper-convergedinfrastructure. Don’t treat it as aseparate technology silo. Performance at scale—Oversubscription and spine-densitybest practices will be needed toensure performance at scale. Simplify the complexity—Amultirack architecture cannot bebuilt spontaneously. Logicalplanning and a massive number ofphysical connections are anecessity.VxRack System 1000networking benefits Standardized and repeatable Easily extensible Greatly simplifies operations Lowers risk Superior application performanceat scaleA hyper-converged network can be difficult to build as needs arise and many solutionssimply exclude it. Overlooking the network makes it very difficult to plan for growthand as the environment scales, performance degrades. These forgotten componentsconsist of the physical, top-of-rack switches, as well as software defined networking(SDN) technologies.The VxRack with FLEX Nodes encompasses support for networking—both physical andvirtual. Physical networking consists of a leaf-spine topology with top of rack (ToR) andspine switches. Each physical rack contains two ToR switches, which control network trafficand redundancy, and a management switch for out-of-band connectivity. With scale-outacross multiple racks, east-west traffic is fully self-contained. Connectivity between racks isprovided using the two inter-rack spine switches.When designing a network, oversubscription, spine density, switch ports, high density,low density, wire rates, are just a few of the many technical details that need to beconsidered. The VxRack with FLEX Nodes was designed with industry best practicesalready applied. Best-in-class Cisco Nexus ToR and Spine switches provide 10 GbE or40 GbE IP connectivity between VxRack with FLEX Nodes and the external network forsuperior performance. Unlike other solutions in the market, where networkbottlenecks limit the scale of hyper-converged infrastructures, the 10 GbE networkswitches within the VxRack with FLEX Nodes eliminate these restrictions and providesa path for future growth.Extreme Application PerformanceEvery node in the VxRack with FLEX Nodes cluster is used in the processing of I/Ooperations, making all I/O and throughput accessible to any application within thecluster. Such massive I/O parallelism eliminates bottlenecks. Throughput and IOPSscale in direct proportion to the number of nodes added to the system, improvingcost/performance rates with growth. Performance optimization is automatic; wheneverrebuilds and rebalances are needed, they occur in the background with minimal or noimpact to applications and users. The VxRack with FLEX Nodes system autonomouslymanages performance hot spots and data layout.

DAS storage onservers within the VxRack with FLEX Nodes is virtualized into a shared network-basedblock storage that is similar to SAN storage. This makes it easy to achieve extremescale-up to 1000 nodes. Customers can start with a minimum of four nodes andrapidly add more based on their business needs. ScaleIO optimizes resource allocationwith performance that scales linearly.SpecificationsVxRack with FLEX Nodes makes the transition to a hyper-converged and softwaredefined storage simple by removing complexities, such as designing and integrating abuild-it-yourself solution.
