Evolution of the Data Center CONSOLIDATION of assets VIRTUALIZATION of servers & storage CONVERGENCE of networks QFX3500 LAN SAN FCoE Now there is a lot of talk about designing and building out a green, extremely efficient virtual data center and Network Convergence plays a big part in that. You see, there are many degrees of data center efficiency, and there are several key steps companies need to take to arrive at an Intelligent Converged Data Center. The first step of data center efficiency is the consolidation of physical servers and storage systems. We’re all familiar with deploying massive consolidation strategies whereby you consolidate your stranded midrange storage systems into your high-end enterprise-class storage systems and the same applies for servers. The next step beyond consolidation is the virtualization of your physical assets . For blade servers, this means using hypervisors to create dozens or hundreds of virtual machines in a single system. For storage devices, this means virtualizing multiple storage systems under common management so that they can be partitioned like one giant hard drive. Now the next degree of data center efficiency—one step beyond virtualization—is the convergence of your networks. You can consolidate your assets, you can virtualize them, but ultimately your data center will not be operating at peak levels of efficiency unless you have converged your mixed protocols supporting your common applications. Network Convergence, along with Virtualization of the server, network and storage infrastructure are driving the next gen data center toward a service-based, cloud-enabled computing model Network Convergence lowers both CAPEX and OPEX as there are a lot less adapters, switches, and cables to buy and a lot less power and cooling required. The Transition to convergence can be done in a phased approach, protecting investments in existing LAN and SAN equipment, tools and training, avoiding disruptions to mission-critical systems and applications. Convergence improves IT’s ability to provide services to their clients. A converged network enables applications to be implemented over whatever protocols provide the service levels that are appropriate for the business requirements of the applications. I/O is a key element I/O bandwidth requirements are exploding, you can expect 100 fold increase within 72 months Maximize I/O efficiency with protocol offloads, protect CPU utilization Realize reductions in capital and operating expenditures Data center computing is in the process of moving to the cloud and network convergence using enhanced Ethernet is an enabling technology HPC

Advanced management functionality Dozens of integrated tools let you do more with your fabric! QuickTools, Adaptive Trunking, Drag-and-drop Zoning Lowest lifecycle costs World-class functionality included with base product Affordable single site license for advanced software Fewer per-switch license upgrade fees The QFX3500 switch delivers a high-performance, ultra low latency, feature rich L2 and L3 solution for supporting a wide range of deployment scenarios including traditional and virtualized data centers, high-performance computing, network-attached storage, converged server I/O, and cloud computing. A versatile, compact, high-density 10GbE platform that runs the same Junos OS as other Juniper switches, routers and security platforms, the QFX3500 also delivers a fabric-ready edge solution for the Juniper Networks QFabric architecture. For converged server edge access environments, the QFX3500 is a standards-based Fibre Channel over Ethernet (FCoE) transit switch and FCoE to Fibre Channel (FCoE-FC) gateway, protecting customer investments in existing data center aggregation and Fibre Channel storage area network (SAN) infrastructures. When deployed with other components of the Juniper Networks QFabric architecture, the QFX3500, which is manageable by Junos Space, delivers a fabric-ready QF/Node edge solution that contributes to a high-performance, low latency fabric, unleashing the power of the exponential data center for users migrating from traditional multitier networks. The QFX3500 offers 63 dual-mode small form-factor pluggable transceiver (SFP+/SFP) ports and four quad small form-factor pluggable plus (QSFP+) ports in a 1 U form factor, delivering feature-rich L2 and L3 connectivity to networked devices such as rack servers, blade servers, storage systems and other switches in highly demanding, high-performance data center environments. Juniper Networks helps enterprises simplify their data center network architecture by collapsing it into two tiers with Virtual Chassis fabric technology, and finally, to one tier with QFabric. By leveraging a common operating system, an open network automation platform, and an industry-leading product and services portfolio, we help to reduce the total cost of ownership and provide performance, scale, and agility.
