Transcript of "Bolstering Campus Networking Infrastructure To Optimize Wireless Access"

  1. 1. 24 2014 Issue 02 | Dell.com/powersolutions Features Reprinted from Dell Power Solutions, 2014 Issue 2. Copyright © 2014 Dell Inc. All rights reserved. T he groundswell of bring- your-own-device (BYOD) initiatives has become a major force driving mobility and wireless network access, leading all types and sizes of organizations to rethink their mobility infrastructure. Over the course of any given work day, an employee typically uses a mix of two or more devices, such as smartphones, tablets and laptops. Moreover, workers are using mobile devices to access content that is richer than before. They need minimal latency for multimedia-heavy, real-time applications, including the Microsoft® Lync® unified communications platform and Citrix® virtual desktop infrastructure. Data- intensive usage, such as uploading and downloading to Dropbox® or Microsoft® OneDrive cloud-based hosting services, requires high bandwidth. To deliver the performance demanded by burgeoning ranks of mobile workers and an exponentially growing number of devices, organizations must tune the IT infrastructure for optimal network bandwidth and capacity. A panoply of mobile users and devices calls for an enhanced mobility infrastructure that supports the demands of today’s content-rich applications. Four key components form the basis of a flexible, end-to-end network access solution.

IT organizations also need ways to maintain control over data, applications and networks as they expand access to online resources. Making the right infrastructure choices can help organizations meet evolving performance and security requirements while avoiding the cost and complexity of maintaining numerous point solutions. In particular, an infrastructure built on industry standards helps keep capital expenses low by enabling easy integration of a wide range of options. Creating a modern mobility infrastructure Four main infrastructure components are required to support wireless access needs and deliver an excellent end- user experience — keeping in mind that any solution is only as good as its weakest link. For example, increasing the number of wireless access points can be a good first step. However, if the network does not support the added capacity, the organization may not obtain the desired results. 1. Intelligent wireless access points and controllers To handle the increasing density of mobile devices without sacrificing performance, organizations can add wireless access points and adopt high- performance solutions based on the latest IEEE 802.11ac standard, also referred to as Gigabit WiFi. Access points based on 802.11ac are designed to deliver up to 1.3 Gbps transfer speeds, up to three times faster than the 450 Mbps of the previous- generation IEEE 802.11n standard. The Dell Networking W-Series family of wireless networking solutions includes mobility controllers and access points that support the latest standards, including 802.11ac. These access points can be powered by standard IEEE Power over Ethernet Plus (PoE+), enabling organizations to extend the life of their existing wired infrastructure while upgrading to the latest mobility solution — avoiding capital investments for wiring power infrastructure upgrades. Another way to boost performance in dense deployments is to reduce congestion by balancing clients across access points. To minimize IT involvement, Dell Networking W-Series solutions incorporate ClientMatch™ technology, which is designed to steer clients automatically to the optimal access point. This client optimization leads to a boost in overall WiFi performance and consistent, predictable performance for each user. 2. Scalable wired infrastructure The switching infrastructure should provide the scalability and performance to support the bandwidth and throughput requirements of a large number of client devices and applications. Organizations should account for specific usage patterns within each campus location to optimize network deployment in terms of cost and performance. In addition, organizations may need to upgrade the switches and core networking pathways that connect client devices to application servers and storage or out to the internet. Dell offers standards-based access and aggregation switches designed to scale network infrastructure as well as provide PoE+ for access points. Dell Networking N-Series switches are designed to interoperate within an organization’s existing network infrastructure and be managed together with switches in a multivendor environment. 3. Streamlined network management Centralized management is essential, helping administrators quickly identify sources of client, user and network problems without toggling between multiple tools and screens. Wireless network management using the Dell AirWave™ management suite provides the context and control needed to quickly identify, troubleshoot and resolve issues. AirWave offers device discovery, classification and diagnosis as well as reporting and analysis capabilities. Administrators can configure and provision access points, distribute firmware and enable compliance across multivendor, multisite environments through a centralized interface. AirWave supports the portfolio of Dell Networking W-Series wireless networking products. To manage Dell network switches from campus to data center, administrators Making the right infrastructure choices can help organizations meet evolving performance and security requirements while avoiding the cost and complexity of maintaining numerous point solutions.

OpenManage Network Manager helps save time and lower costs by automating common, labor-intensive network management operations. 4. Flexible access management Organizations also must manage employee and guest access to the network; each user needs to have the right access privileges based on who they are and what device they are using. Dell Networking W-Series ClearPass Access Management System™ software lets administrators secure wireless network access to guests and employees from a single, unified platform. ClearPass scalability enables administrators to manage role-based access for thousands of users whether they are local or dispersed geographically. Administrators also can use ClearPass to manage policies that help prioritize traffic according to applications, providing the required bandwidth for users based on their roles, device types and location. Self- registration capabilities let employees and guests gain the access they need, freeing IT administrators from time-consuming onboarding and provisioning processes. Preparing the way for continuous innovation and growth By understanding their organization’s needs, knowing the technologies available and right-sizing the solution, IT professionals can implement a network infrastructure that promotes employee flexibility and productivity while enhancing policy management. From switches and access points to management tools and firewalls, Dell brings together solutions designed to address specific needs created by mobility and BYOD, such as enabling mobile access, preparing the infrastructure and maintaining security to accommodate the rapid increase in users. For example, Dell has released a campus reference architecture to speed network designs and enable network growth for fast productivity gains. Dell also offers a full range of services, including comprehensive product and technical support. Organizations can draw on the deep expertise of installation and deployment services to help assess needs and design and implement a mobility strategy. Through Dell support services, IT groups can access networking professionals 24 hours a day for help with configuration, troubleshooting and diagnostics. Using modern networking solutions and comprehensive services, organizations can build an end-to-end network with products from a single vendor or easily integrate capabilities into an existing multivendor environment. Ultimately, this comprehensive approach helps organizations optimize their network infrastructure to support mobile users today and meet evolving requirements for access, performance, security, scalability and ease of management. By understanding their organization’s needs, IT professionals can implement a network infrastructure that promotes employee flexibility and productivity and enhances policy management.
