The N1 Grid is Sun's vision, strategy, and architecture—and a set of products—that redefine the nature of data center computing. The N1 Grid architecture uses the network, physically and logically, as its fundamental organizing principle.This book enables the reader to implement service-centric data center solutions through the use of N1 Grid-based principles and architectures, which are more efficient and flexible. It opens with an overview of how this approach evolved and then takes the reader through the process of preparing, architecting, and implementing N1 Grid-based solutions.

The Definitive Guide to Protecting Enterprise DataYour enterprise data is your most critical asset. If it's compromised, your business can be destroyed. Don't let that happen-leverage today's state-of-the-art strategies, best practices, and technologies and protect your critical information. In Data Protection and Information Lifecycle Management, leading industry consultant Tom Petrocelli presents a systematic, coherent approach to planning and implementing cost-effective data protection. This book introduces Information Lifecycle Management (ILM), a powerful new strategy for managing enterprise information based on its value over time. The author explains emerging techniques for protecting storage systems and storage networks, and for integrating storage security into your overall security plan. He also presents new technical advances and opportunities to improve existing data-protection processes, including backup/restore, replication, and remote copy. Coverage includes A complete, unique framework for considering and planning data protectionUnderstanding storage technology from the standpoint of data protection Architecting more effective backup/restore solutionsUsing remote copy and replication to keep data synchronized and support immediate failover to hot sitesLeveraging core computer security concepts and strategies to protect your most critical dataSecuring your entire storage infrastructure, not just serversUsing policy-driven data protection and Data Lifecycle Management (DLM) to improve security and reduce costUsing ILM to identify your highest-value data and choose the right ways to protect it Data Protection and Information Lifecycle Management is an indispensable resource for IT executives who must plan and implement strategies for data protection; administrators who must protect data on a day-to-day basis; and product managers, consultants, and marketers responsible for crafting superior data-security solutions.

This book covers basic concepts of business statistics, data analysis, and management science in a spreadsheet environment. Practical applications are emphasized throughout the book for business decision-making; a comprehensive database is developed, with marketing, financial, and production data already formatted on Excel worksheets. This shows how real data is used and decisions are made. Using Excel as the basic software, and including such add-ins as PHStat2, Crystal Ball, and TreePlan, this book covers a wide variety of topics related to business statistics: statistical thinking in business; displaying and summarizing data; random variables; sampling; regression analysis; forecasting; statistical quality control; risk analysis and Monte-Carlo simulation; systems simulation modeling and analysis; selection models and decision analysis; optimization modeling; and solving and analyzing optimization models. For those employed in the fields of quality control, management science, operations management, statistical science, and those who need to interpret data to make informed business decisions.

A comprehensive, data-driven introduction to modern spatial data analysis, a field which is playing an increasing role in many areas of research and policy making. Provides full explanations for a wide variety of methods, with illustrated with case studies. Data sets for all the case studies are included on an accompanying computer disk, together with a substantial interactive DOS software package for the display and analysis of spatial data.

Build real-world, end-to-end network monitoring solutions with Nagios   This is the definitive guide to building low-cost, enterprise-strength monitoring infrastructures with Nagios, the world’s leading open source monitoring tool. Network monitoring specialist David Josephsen goes far beyond the basics, demonstrating how to use third-party tools and plug-ins to solve the specific problems in your unique environment. Josephsen introduces Nagios “from the ground up, ” showing how to plan for success and leverage today’s most valuable monitoring best practices. Then, using practical examples, real directives, and working code, Josephsen presents detailed monitoring solutions for Windows, Unix, Linux, network equipment, and other platforms and devices. You’ll find thorough discussions of advanced topics, including the use of data visualization to solve complex monitoring problems. This is also the first Nagios book with comprehensive coverage of using Nagios Event Broker to transform and extend Nagios. Understand how Nagios works, in depth: the host and service paradigm, plug-ins, scheduling, and notification Configure Nagios successfully: config files, templates, timeperiods, contacts, hosts, services, escalations, dependencies, and more Streamline deployment with scripting templates, automated discovery, and Nagios GUI tools Use plug-ins and tools to systematically monitor the devices and platforms you need to monitor, the way you need to monitor them Establish front-ends, visual dashboards, and management interfaces with MRTG and RRDTool Build new C-based Nagios Event Broker (NEB) modules, one step at a time Contains easy-to-understand code listings in Unix shell, C, and Perl   If you’re responsible for systems monitoring infrastructure in any organization, large or small, this book will help you achieve the results you want–right from the start.   David Josephsen is Senior Systems Engineer at DBG, Inc., where he maintains a collection of geographically dispersed server farms. He has more than a decade of hands-on experience with Unix systems, routers, firewalls, and load balancers in support of complex, high-volume networks. Josephsen’s certifications include CISSP, CCNA, CCDA, and MCSE. His co-authored work on Bayesian spam filtering earned a Best Paper award at USENIX LISA 2004. He has been published in both ;login and Sysadmin magazines on topics relating to security, systems monitoring, and spam mitigation.   IntroductionCHAPTER 1 Best PracticesCHAPTER 2 Theory of Operations CHAPTER 3 Installing Nagios CHAPTER 4 Configuring Nagios CHAPTER 5 Bootstrapping the Configs CHAPTER 6 WatchingCHAPTER 7 VisualizationCHAPTER 8 Nagios Event Broker Interface APPENDIX A Configure OptionsAPPENDIX B nagios.cfg and cgi.cfgAPPENDIX C Command-Line OptionsIndex
