1. Introduction Today the Data Center is the heart of most companies’ operations, pumping the lifeblood (i.e. data) to and from users, storage devices and the world wide web. The importance of effective management of increasingly large amounts of data is prompting many companies to significantly upgrade their current operations, or to create brand new data centers from greenfield. At the same time, economic conditions are forcing companies to focus on efficiency and simplification. As a result, Data Center optimization and/or consolidation may be on your agenda. When considering a new Data Center or the consolidation of multiple sites, many questions arise: 1. Where should the Data Center be located? 2. How big should it be 3. How much power consumption can be expected? 4. What is the uptime target (what tier, how many 9's do you wish)? 6. What are the technologies to use? 7. How should the Data Center be laid out? 8. How long is the life span? Upgrading current systems may at first seem easier, but this too will have its own set of questions 1. Should we continue to use the same exact products, or start utilizing higher grade options? 2. Space is already tight; what higher density options are available? 3. What are the distance limitations for expected applications? 4. What new standards do I need to be aware of? This guide will examine all of these questions and more as we provide the information necessary to properly design a Data Center. www.commscope.com 3
