  3. 3. 3 Executive summary Today we live in a global, 24/7 economy that is pushing the pace of business to staggering speeds. Forward-thinking leaders of midsize and large businesses are reevaluating their business models and looking to technology innovation to provide strategic advantage. Many businesses are inhibited by their legacy network infrastructures, which are often proprietary. Their networks are no longer able to meet current business demands, let alone support business growth or new technological innovations. CIOs and network managers are challenged to enable workers to be mobile, continually connected, and broadly dispersed, and to interact with one another as well as partners and customers at any time. At the same time, budgets are constrained, so IT executives must find ways to increase network capabilities and performance without increasing costs. Bringing next-generation technologies into your network enables you to better meet today’s business demands and put you in a great position to grasp new opportunities. Businesses can support new demands and can gain competitive advantage with modern network infrastructures that are open and based on industry standards. A modern network infrastructure can also help you reduce the TCO of your network in a number of ways: • Modern network infrastructures use open and industry-standard components, eradicating costly vendor lock-in. • Modern networking technologies are automated and intelligent, so your IT staff can dedicate more time to supporting business growth. • Network management is centralized, simplified, and streamlined through a single-pane-of-glass management platform, removing the need to maintain multiple management platforms. • Branch office network management is simplified and doesn’t require dedicated IT staff at remote locations. If your enterprise is looking for ways to thrive in the new business world order, read on. We give you five great reasons to modernize your network now, and we explain how HP, with its advanced networking technologies, can help you break free from your legacy network. Read this paper if you are a CTO, CIO, or IT manager for a midsize or large enterprise interested in advancing the capabilities, performance, scalability, and security of your network to support game-changing technologies such as virtualization, cloud computing, mobility, and unified communications & collaboration (UC&C), as well as lowering the total cost of ownership (TCO) of your network infrastructure.
  4. 4. 4 Help your organization thrive through mobility and “BYOD.” As workers use their own digital devices to access corporate applications, mobility has become the norm. This practice is known as “bring your own device,” or BYOD. Consider these IDC top predictions for 2012 and beyond:1 • In 2012, the total unit shipments of smartphones and media tablets will more than double the unit shipments of PCs. Spending on these devices now exceeds that for PCs. • By 2014, the number of “intelligent communicating” devices on the network will outnumber “traditional computing” devices by almost 2 to 1. The mobility explosion has already overtaken the enterprise, as workers connect to the corporate network with or without permission. The preferred way to connect will be through WLAN, rather than lower speed 3G or 4G networks. Progressive companies will help their workers use these smart devices to access more than just email and calendaring applications. Workers must have continual access to their business intelligence, and companies that develop and encourage the use of customized mobile applications will keep their employees’ fingers on the pulse of the business. The extensive use of mobile devices impacts enterprise networking in several ways, including an increasing need for secure wireless access that has sufficient bandwidth and consistent performance to deliver streaming video and other applications—anytime, in virtually any location. Businesses must be able to protect both company- and employee-owned digital devices, while specifying appropriate network access rules and policies. Increase business productivity through unified communications & collaboration. Companies of all sizes are looking to help workers collaborate more effectively and efficiently, and to provide customers with more meaningful interactions. This often creates an explosion in demand for handling rich media and applications such as streaming video, large image files, audio, course work materials, video collaboration, VoIP, and social business solutions. Rather than support individual applications, it’s much more cost-effective and productive to implement a single integrated solution for unified communications & collaboration. A typical UC&C system has location-aware capabilities that allow employees to work just about anywhere—in the office, at home, on the road—using a variety of Internet-enabled devices, including smartphones, wireless tablets, and of course, desktop and notebook computers. While implementing a UC&C strategy requires planning, an investment in new equipment, and considerable setup, the end result reduces costs for management and communication services and allows workers to collaborate with ease. With all of these services now running over your Internet connection or WAN, you must consider how it impacts latency and quality of service (QoS). Moreover, workers who are mobile or in a branch office expect to have the same user experience as their counterparts in the main office. 1  IDC, IDC Predictions 2012: Competing for 2020, #231720, Dec 2011
  5. 5. 5 Support growth and expansion to branch offices and other locations. Many midsize and large enterprises are growing, both organically and through acquisitions. To enhance customer services, businesses are delivering services closest to the customers. This leads to numerous branch locations such as remote offices, new storefronts, warehouses, and factories. If locales were acquired through acquisitions, there can be a heterogeneous collection of networking solutions throughout the business. Nevertheless, workers in all these locations need access to the productivity-enhancing tools in which the enterprise has invested, and they expect to have a user experience that is similar to that of the corporate headquarters. With little to no IT personnel in the branches, corporate IT organizations must deliver services remotely. What’s more, branch office networks must be protected by comprehensive security policies and enforcement to help achieve business continuity. Modern networking solutions can allow you to roll out a standardized solution that enables simple, secure access to a full complement of rich applications with high performance within the various branch locations and be remotely supported. Find cost and innovation advantages through multivendor networks. Every enterprise has an extensive investment in an existing networking infrastructure, often with most (if not all) major components coming from just one vendor. This may no longer be the best approach to building and maintaining a total network infrastructure. According to the Gartner research titled “The Disaggregation of the Enterprise Network”: “The network infrastructure market has evolved rapidly during the past three years, from one in which most organizations adhered to a single-vendor architecture to a more business-driven network architecture that increasingly uses a multivendor, best-of-breed approach. Our research found there is no operational advantage to maintaining a single-vendor approach (see ‘Debunking the Myth of the Single Vendor Network’).” Some companies believe that sourcing all components from just one networking vendor will keep their operations simple, consistent, and easy to manage. After extensive analysis of hundreds of enterprises, Gartner analysts conclude that there are benefits to introducing a second networking vendor, including reducing complexity and saving budget money: “Although there is no operational justification for choosing a single-vendor architecture, we believe that enterprises would benefit from evaluating the vendors’ operational capabilities, because there is evidence that different approaches to network equipment design and operational focus can reduce network complexity. Those that follow this new approach will find that they build a better network without functional compromises or unnecessary overbuilding, while saving substantial amounts of their total network infrastructure budgets — in most cases, demonstrating 20 percent to 25 percent total life cycle savings. Functional and financial analysis has replaced sole-sourcing convenience, due to the compelling benefits of a disaggregated approach to network design.”2 In addition, bringing in a second networking vendor will help you introduce technology innovations that can deliver real business advantages. 2  Debunking the Myth of the Single Vendor Network
  6. 6. 6 Provide the path to virtualization and cloud computing for greater flexibility and agility. Enterprises are eager to embrace cloud computing because of its potential for improving agility, cutting costs, and reducing time to revenue. Through cloud computing, enterprises are transforming from a service provider role to a service broker. IT organizations deliver services to end-users that are obtained from a variety of sources, including public, private or hybrid clouds, outsourcing providers and managed service providers. To deliver these services, enterprises often need to consolidate and virtualize data centers, as well as develop and deploy cloud service solutions to meet the pace and scaling needs of the business. The underlying architecture of “the cloud” is a converged infrastructure in which open and industry standards-based servers, storage, and networking technologies are preintegrated into a single computing framework. Additional provisioning and management technologies are layered on top to provide an entry into cloud computing. The network must be agile and flexible so it can effectively obtain and deliver services from the various aforementioned sources. An industry standards-based converged infrastructure approach to IT service delivery helps overcome the complexity, rigidity, and high cost created by the sprawl of traditional IT. Businesses can reinvest the savings into innovative and strategic initiatives. Open networks are the way forward as you look toward the cloud. Your enterprise needs a network that can easily move applications and services to the cloud in a seamless, open, and multivendor way. Characteristics of a modern network Of course, there are many more than the previous five reasons to modernize your enterprise network. Mobility, BYOD, UC&C, virtualization, and cloud computing are driving more application traffic to the network, and the underlying networks must change to support them. A legacy network design will eventually reach a breaking point that will constrain business. Further, enterprises that don’t segment their network infrastructure could see higher costs and increased vendor lock-in. As you reevaluate your network architecture, consider how to incorporate the following characteristics of a modern network: • Based on open industry standards • Scalable in terms of functionality, connectivity, and capacity • A consistent and pervasive approach to security • A simplified architecture to increase agility • A simplified approach to managing the entire network
