The High-Performance Data Center

  1. 1. SOLUTION BROCHURE The high-Performance DaTa cenTer Reducing Data Center Network Complexity and Total Cost of Ownership
  2. 2. High-Performance Data Center Solution Overview The Juniper Networks® Data Center Infrastructure Solutions reduce the total cost of network ownership by introducing a new and innovative network architecture. The architectural innovations delivered via a high- performance product portfolio significantly reduce not only the cost and complexity of acquiring and managing the network infrastructure, but also the time taken to deploy new applications and services. This portfolio of routing, switching, and security products use a single network operating system—Juniper Networks JUNOS® Software—and is managed by a single network management system. The improved simplicity, agility, and efficiency provided by these solutions, benefit businesses ranging from enterprises of varying sizes to government agencies and service providers. 2
  3. 3. The Juniper Networks Data Center Infrastructure Solutions simplify data center security and network design. By collapsing the multiple switching tiers present in traditional architectures, the new simplified network design requires fewer devices and interconnections—leading to improved efficiencies in space, power, cooling, and management. This reduction in equipment and improved performance with high availability (HA) is achieved by combining Virtual Chassis technology with line-rate performance. The solutions also simplify and improve the efficiency of deploying security services by consolidating the “security sprawl” of traditional designs into much fewer high- capacity and high-performance chassis-based products. Based on a dynamic services architecture, these products allow breakthrough improvements in the speed of deploying new security services—made possible by “true services integration” within a single operating system. Consolidation of security services not only makes the security infrastructure more energy and space efficient, but also makes operations much simpler by reducing the total number of devices that need to be managed. Performing all the security services without passing through multiple limited-scale and single-function appliances drastically lowers application latency across the network. Advanced routing technologies and platforms deliver agility of business operations by improving the scalability of converged core networks that span multiple data centers. Data centers can now rapidly deploy new applications and support new services with less complexity to achieve business growth objectives with improved performance and lower total cost. challenges The traditional data center has become overly complex, costly, and extremely inefficient. Arguably, it is the single biggest hurdle that prevents businesses from fully reaping the productivity benefits offered by other innovations occurring in the data center, including: server virtualization, storage over Ethernet, and evolution in application delivery models. Traditional architectures that have stayed unchanged for over 10 years employ excessive switching tiers, largely to work around low performance and low-density characteristics of the devices used in those designs. Growth in the number of users and applications is almost always accompanied by an increase in the number of “silos” of more devices— both for connectivity as well as for security. Adding further insult to injury, these upgrades introduce new untested operating systems to the environment. The ensuing additional capital expenses, rack space, power consumption, and management overhead directly contribute to the overall complexity of maintaining data center operations. Unfortunately, instead of containing the costs of running the data center and reallocating the savings into the acceleration of productivity-enhancing business practices, the IT budget continues to be misappropriated into sustaining existing data center operations. 3
  4. 4. Trends Data center consolidation and virtualization trends are accelerating in an effort to optimize resources and lower cost. Consolidation, virtualization and storage are placing greater network performance and security demands on the network infrastructure. While server virtualization greatly improves server resource utilization, it also greatly increases the amount of data traffic on the network infrastructure. Applications running in a virtual server environment require low latency, high throughput, robust QoS and HA. Increased traffic per port and performance demands tax the traditional network infrastructure beyond its capabilities. Furthermore, high-bandwidth and low-latency data storage requirements—and the increased adoption of iSCSI and NAS—add to the demands on the network infrastructure. With the future standardization of Fiber Channel over Ethernet (FCoE), this technology promises to place even greater bandwidth and performance demands on the network infrastructure. Additionally, new application architectures, such as Service Oriented Architecture (SOA) and Web Oriented Architecture (WOA), and new services—such as cloud computing, desktop virtualization, and Software as a Service (SaaS)—create increased performance and bandwidth demands upon the data center network infrastructure. These heightened demands often require new platforms in the data center, contributing to increased complexity and cost. IT data centers are rapidly migrating to the high-performance network infrastructure recommended by Juniper Networks to improve data center-based productivity, while lowering time to market for new data center applications and reducing operational cost. 4
  5. 5. Juniper Networks Solution Portfolio for the Data Center Juniper Networks Data Center Infrastructure Solutions provide operational simplicity, agility, and efficiency to dramatically simplify the network with the following key technologies: • Virtual Chassis technology, combined with wire-rate 10 Gigabit Ethernet performance in the Juniper Networks EX Series Ethernet Switches, reduces the number of networking devices and interconnections. This effectively eliminates the need for an aggregation tier—contributing to a significant reduction of capital equipment cost and network operational costs, improved application performance, and faster time to deploy new servers and applications. • Dynamic Services Architecture in the Juniper Networks SRX Series Services Gateways consolidates security appliances with distinct functions into a highly integrated, multifunction platform that results in simpler network designs, improved application performance—and a reduction of space, power, and cooling requirements. • Network virtualization with MPLS in the Juniper Networks MX Series Ethernet Services Routers and the Juniper Networks M Series Multiservice Edge Routers enables network segmentation across data centers and to remote offices for applications and departments without the need to build separate or overlay networks. • JUNOS Software operates across the network infrastructure, providing feature parity and reducing certification time for new releases. • Juniper Networks Network and Security Manager (NSM) provides a single portal with end-to-end visibility across the data center for security, switching, and routing infrastructure. • J-Care Technical Services provide automated incident management and proactive analysis assistance through the Advanced Insight Solutions technology resident in JUNOS. Juniper Networks high-performance data center network architecture reduces cost and complexity by requiring fewer tiers of switching—and consolidating security services, a common operating system, and one extensible model for network management. 5
  6. 6. reducing Devices, interconnections, and Tiers in the Data center network In many data center environments, three or more tiers of Ethernet switches are required to aggregate servers to the network core. To reduce the number of switching tiers, Juniper Networks Data Center Infrastructure Solutions employ Virtual Chassis technology, which enables up to 10 EX4200 switches to be interconnected as a single, logical device. Although collectively the member switches behave as a single platform, each individual physical switch has its own power supply and fan tray, providing high Ethernet-switching availability within the Virtual Chassis configuration. Using Virtual Chassis technology for top-of-rack or end-of-row deployments to aggregate servers in the data center dramatically reduces switch aggregation links and ports. Rather than requiring redundant links for each physical switch to ensure HA, redundant links are only needed for each Virtual Chassis group. Depending on the configuration, some switches in the Virtual Chassis group may not have uplinks but instead leverage uplinks on the other member switches. A high-capacity backplane connects all of the physical switches in the Virtual Chassis configuration, allowing for failover to interconnected backup switches. This configuration significantly reduces the number of links required to ensure network connection redundancy, while reducing or eliminating the need for Spanning Tree Protocol in the access-switching tier of the data center. This architecture eliminates an aggregation tier and leverages the EX4200 switches as top-of-rack or end-of-row switches in a Virtual Chassis configuration, connecting directly to a pair of Juniper Networks EX8208 core data center switches. Delivering non-blocking, high-density performance, the EX 8208 delivers 192 wire-rate 10 Gigabit Ethernet ports in a single rack and can effectively collapse the aggregation and core into a single tier. When the integration of switching and advanced routing services are needed, the EX4200 switches connect directly to a pair of Juniper Networks MX960 Ethernet Services Routers in the data center core network. The MX960 delivers scalability and flexibility with up to 1 million MAC addresses, 8,000 to 16,000 VLANs, and up to 64,000 circuit IDs. Layer 3 and feature-rich MPLS services allow data center administrators to achieve improved traffic engineering, recovery times, QoS, network virtualization, and convergence—thus improving performance with the added value of lowering total cost of ownership. 6
  7. 7. enhancing network Utilization Through Virtualization The Juniper Networks data center network architecture employs a mix of virtualization technologies—such as Virtual Chassis technology with VLANs and MPLS-based advanced traffic engineering, VPN enhanced security, QoS, VPLS, and other virtualization services. These virtualization technologies address many of the challenges introduced by server, storage and application virtualization. For example, Virtual Chassis supports low-latency server live migration from server to server in completely different racks within a data center and from server to server between data centers in a flat Layer 2 network when these data centers are within reasonably close proximity. Virtual Chassis with MPLS allows the Layer 2 domain to extend across data centers to support live migration from server to server when data centers are distributed over significant distances. Juniper Networks virtualization technologies support the low latency, throughput, QoS and HA required of server and storage virtualization. MPLS-based virtualization addresses these requirements with advanced traffic engineering to provide bandwidth guarantees, label switching and intelligent path selection for optimized low latency and fast reroute for extremely HA across the WAN. MPLS-based VPNs enhance security with QoS to efficiently meet application and user performance needs. These virtualization technologies serve to improve efficiencies and performance with greater agility while simplifying operations. For example, acquisitions and new networks can be quickly folded into the existing MPLS-based infrastructure without reconfiguring the network to avoid IP address conflicts. This approach creates a highly flexible and efficient data center WAN. Juniper Networks virtualization technologies are unmatched in their support to improve network utilization and improve productivity with lower total cost. a common oS and management Platform JUNOS Software is the field-proven operating system powering Juniper Networks routing, switching and security infrastructure in the data center. It enables the consolidation of security and networking onto a common operating system with feature consistency and interoperability across the entire data center network. Manageability and flexibility of the data center are enhanced to address business needs as they arise and improve data center operations. A common set of tools are used to monitor, administer, and troubleshoot the network—allowing data center operations teams to function more efficiently with less training, while providing higher availability. Unlike any other networking infrastructure OS on the market, JUNOS provides one operating system, enhanced through a single release train and developed upon a common modular architecture—giving enterprises a “1-1-1 advantage.” 7
  8. 8. JUNOS follows a strict single release train, which delivers a superset of features in each subsequent release. The single code train ensures a high-quality product with lower error rates and greater functionality as compared to other vendor alternatives, which are forced to maintain multiple versions of code based on different development methodologies. Rather than stretching test and quality assurance resources around a large number of software code versions, Juniper Networks teams focus a high-quality effort around this single version of code. JUNOS is built using a modular architecture designed for flexible yet stable innovation across many types of hardware platforms. This adds to the availability and robustness of platforms running JUNOS in the data center. HA is enhanced by isolating potential incidents related to software features and functions through the modular design. Problem isolation also serves to support faster troubleshooting and resolution, helping to ensure maximum data center availability. Integrated Advanced Insight Solutions provide automated support features for streamlined efficiency. Although JUNOS is robust in nature, the most frequent cause of network outages is human error. The JUNOS Software human interface has been built with this in mind and has specifically been designed to reduce the potential of human error. Configuration changes must be confirmed, and it is easy to roll back to previously known working configurations. This contributes to the high overall availability of JUNOS and its value in the data center to support business-critical applications. Additionally, scheduled downtime requirements are minimized with JUNOS Software-based features—such as in-service software upgrade (ISSU), which enables software upgrades and patches to be deployed without requiring a scheduled downtime maintenance window. A recent survey by Lake Partners of more than 120 network operators found that many JUNOS customers spend an average of 25 percent less time on common network operations tasks compared to those working with alternative operating systems. Further, the survey reported on average a 54 percent reduction in time spent on troubleshooting and unplanned events. These statistics demonstrate the improved simplicity and operational efficiencies enabled by JUNOS. consolidated Security Traditionally, organizations have been forced to balance and compromise on network security versus performance for applications in the data center. Juniper Networks eliminates this trade-off consideration and makes it possible for data centers to have the robust network security they desire with performance to meet the most demanding application and user environments. Going further, Juniper Networks can consolidate network security for the data center into fewer devices— with centralized policy and visibility to greatly improve the operational efficiency of the data center environment. As a result, you can support greater scale and advanced application demands with improved agility and less cost—and without trade-offs in sacrificing security for performance. Juniper Networks SRX5000 line of services gateways consolidates network security services—including firewall functionality, intrusion prevention systems (IPS), Network Access Control (NAC), VPN (IPsec), and attack protection (Denial of Service 8

The SRX5000 Services Gateways can scale to over 120 Gbps in firewall performance with up to 30 Gbps IPS throughput performance, making this platform the fastest integrated firewall and IPS platform in the world. The SRX Series Services Gateway enables identity management with NAT, QoS, and centralized policy control for the data center. This enables control and enforcement of policy within the data center for applications and services that are hosted on a regional to global basis. Such scale greatly reduces the operational overhead and simplifies the deployment of new business-enabling applications. Juniper Networks is the only provider of routing, switching and security infrastructure that provides all of these platforms upon a common operating system with its award-winning JUNOS Software. This facilitates coordinated security across the data center routing, switching, and security infrastructure, while 9

Human Performance-enabling SerVice anD SUPPorT elements of security are enhanced by leveraging the advanced JUNOS configuration interface, which is designed to reduce human errors in network and security Juniper Networks is the leader in configurations and provides commit-confirm and easy rollback of previous working performance-enabling services and support, which are designed configurations. Consolidation around fewer operating systems in the data center to accelerate, extend, and optimize reduces training requirements of data center IT staff, allowing more of the IT staff your high-performance network. to become certified experts on the network and security platforms with less training Our services allow you to bring and associated cost. revenue-generating capabilities online faster so you can realize Many data centers use MPLS and/or VPLS to segment and separate applications, bigger productivity gains, faster users, and functional organizations within the data center. Employing these rollouts of new business models and ventures, and greater market reach, technologies for creating multiple separate virtual networks can be used to while generating higher levels of enhance application performance, while adding a layer of security through multiple, customer satisfaction. At the same separate virtual networks. Many data centers leverage capabilities enabled by time, Juniper Networks ensures Juniper Networks technology to map VLANs to unique routing domains across the operational excellence by optimizing WAN to provide end-to-end QoS requirements for VLAN-associated applications your network to maintain required levels of performance, reliability, and and users. Juniper Networks has established itself as a leader in the development availability. For more details, please and support of routing technologies and brings these associated benefits to bear visit within the data center. In addition to routing across the WAN, frequently, application acceleration is required from the data center to branch-office locations and remote workers. Juniper Networks WX Series Application Acceleration Platforms can accelerate a wide number of latency-sensitive and delay-prone applications from the data center to remote users. Caching and sophisticated acceleration techniques can identify and accelerate WAN traffic with detailed reporting. The reporting capabilities provide management with insights regarding usage and bandwidth demand per application to manage and tune the network to deliver optimal performance. It is not uncommon to have security embedded within switching platforms, but these security features and capabilities are often ignored because the networking side of the IT organization “owns” the switches, and the security side of the IT organization typically deploys purpose-built security devices. However, Juniper Networks enables management virtualization and segmentation of switching platforms so that the security group can configure and maintain the security functionality of the switch, while the networking group can configure and maintain the networking functionality of the switch. The best of both worlds is achieved, with each group maintaining autonomy and control, while virtual security and networking platforms are consolidated to reduce space, power, cooling and associated data center costs.
