10 www.commscope.com Features of Enterprise and Collocated Data Centers Enterprise: Company maintains control over network and data Optimize to business needs Maintain business flexibility No competition for priority of service Collocation: Controlled costs Frees company to focus on business operations Provide backup and redundancy Simplifies process of increasing/decreasing network capacity There is a hybrid of these two center types where a third party provides a data center that is dedicated to a single customer. This is an attempt to maintain the benefits of a private Enterprise center, while allowing a third party to maintain the physical facility. Another twist on data center types concerns companies whose business are their networks and data managed within the data centers. Online catalog, search and social networking sites are good examples of this. IDC terms these as Web 2.0 or Mega Data Centers (IDC, 2008). These data centers are typically “mega” in size as an online company is fully dependent on the speed and capacity of their network to provide customers with instant access to information and transaction capability. The business model for Mega Data Centers forces these companies to focus on low overall costs and they have to factor in power, real estate, taxes and network costs when determining which locations to set their facilities (IDC, 2008).
3. Network Topology Simply defined, a network is a communication system that seamlessly and efficiently connects voice, data, video and other selected applications together. Network speed and complexity have increased over the past 40 years and certain standards emerged out of the various protocols that were created, called topologies. The discussion of cabling topology covers two types of topologies: physical and logical. Physical topology is the way cabling or media is installed and connected to the devices. Logical topology is the way information travels on the cabling or media. A network’s logical topology is not necessarily the same as its physical topology. For example, twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's Token Ring is a logical ring topology, it is physically set up in a star topology. The best physical topology, as recommended by the standards, is a star configuration. Using a physical star, it is possible to implement any logical topology. Network Physical Topologies Star Topologies In a physical star topology, network devices are cabled to meet at a point of concentration, usually a piece of active electronics called a hub, router, switch or node. These actives are then connected to an intermediate point of concentration, and so on, until all traffic meets at a central point. Logical buses, rings and stars can be cabled together into a physical star. The hierarchical and centralized nature of the star permits the easy concentration of cables and components, thus easing maintenance burdens. Network additions can be accommodated easily by a physical connection at any of the collection points. TIA and other standards typically recommend a physical star topology within buildings. www.commscope.com 11
