There, she spoke at Cisco conferences, trained sales staff and partners, authored books, and advised customers. Throughout, Santana illuminates key theoretical concepts through realistic use cases, real-world designs, illustrative configuration examples, and verification outputs. The authors first introduce QoS technologies in high-to-mid-level technical detail, including protocols, tools, and relevant standards. . Leading data center expert Gustavo A. He has specialized in QoS for the past 15 years and authored Cisco TelePresence Fundamentals.
Expert instructors and engineers Wendell Odom and Chad Hintz share preparation hints and test-taking tips, helping you identify areas of weakness and improve both your conceptual knowledge and hands-on skills. The best server selection process takes into account both server load and availability, and the existence and consistency of the requested content. Virtualization is the best way to meet this challenge. It also addresses shifting bandwidth constraints and congestion points; improved hardware, software, and tools; and emerging QoS applications in network security. This series is built with the objective of providing assessment, review, and practice to help ensure you are fully prepared for your certification exam. In addition to discussing relevant concepts and methodologies, the authors address design considerations associated with hardware, topologies, automation, and scalability. The book concludes by discussing universal data center switch architecture concepts in order to clearly understand switching concepts and the newer trends in the Nexus 9000 product portfolio.
This new edition focuses on complex traffic mixes with increased usage of mobile devices, wireless network access, advanced communications, and video. Santana thoroughly explores all components of an end-to-end data center virtualization solution, including networking, storage, servers, operating systems, application optimization, and security. Ron has 21 years of industry experience, including 7 at Cisco. Data Center Virtualization Fundamentals brings together the comprehensive knowledge Cisco professionals need to apply virtualization throughout their data center environments. Matthew McPherson, senior systems engineer and solutions architect for the Cisco Central Select Operation, specializes in data center architectures. Data Center Fundamentals helps you understand the basic concepts behind the design and scaling of server farms using data center and content switching technologies.
Wherever appropriate, significant platform specific behaviors are described and analyzed. An in-depth analysis of the data center technology with real-life scenarios make Data Center Fundamentals an ideal reference for understanding, planning, and designing Web hosting and e-commerce environments. It reflects the growing heterogeneity of video traffic, including passive streaming video, interactive video, and immersive videoconferences. Data centers switch traffic based on information at the Network, Transport, or Application layers. Drawing on their extensive experience in enterprise engagements, the authors present effective solutions for virtualized data centers, high performance computing, ultra-low latency environments, and large-scale data centers. Technical professionals will find invaluable guidance on migrating current data center environments to a policy driven data center. These challenges can be solved in part with the use of data center technology.
The authors begin by reviewing the evolution of the data center server. For each feature, key concepts are presented, followed by basic configuration and detailed troubleshooting techniques, complete with illustrations. Best of all, the authors present all the proven commands, sample configurations, and tips you need to apply these best practices in your data center. It also presents a start-to-finish, step-by-step case study of an enterprise customer who migrated from Cisco Catalyst to a Nexus-based architecture, illuminated with insights that are applicable in virtually any enterprise data center. They examine new QoS demands and requirements, identify reasons to reevaluate current QoS designs, and present new strategic design recommendations. Cisco data center experts Lucien Avramov and Maurizio Portolani thoroughly explain the architecture, concepts, and methodology of the policy driven data center. They can also build cloud infrastructure faster than before.
In this book, you will discover support and configuration best practices for working with Layer 2 and Layer 3 protocols and networks, implementing multicasting, maximizing serviceability, providing consistent network and storage services, and much more. He has 12 years of experience working with service providers and large finance and manufacturing enterprises, and possesses deep technical knowledge of routing, switching, and security. . . . . .
