Cisco Devnet Evolving Technologies Study Guide Cisco DevNet Evolving Technologies Study Guide Nicholas Russo — CCIE #42518 (EI/SP) CCDE #20160041 March 13, 2021 1 Abstract Nicholas Russo holds active CCIE certifications in Enterprise Infrastructure and Service Provider, as well as CCDE. Nick authored a comprehensive study guide for the CCIE Service Provider version 4 examination and this document provides updates to the written test for all CCIE/CCDE tracks. Nick also holds a Bachelor’s of Science in Computer Science, from the Rochester Institute of Technology (RIT) and is a frequent programmer in the field of network automation. Nick lives in Maryland, USA with his wife, Carla, and daughters, Olivia and Josephine. For updates to this document and Nick’s other professional publications, please follow the author on his Twitter, LinkedIn, and personal website. Technical Reviewers: Angelos Vassiliou, Leonid Danilov, and many from the RouterGods team. This material is not sponsored or endorsed by Cisco Systems, Inc.

Author’s Notes This book was originally designed for the CCIE and CCDE certification tracks that introduced the “Evolving Technologies” section of the blueprint for the written qualification exam. Those exams have since been overhauled and many of their topics have been moved under the umbrella of Cisco DevNet. This book is not specific to any certification track and provides an overview of the three key evolving technologies: Cloud, Network Programmability, and Internet of Things (IoT). Italic text represents cited text from another not created by the author. This is often directly from a Cisco document, which is appropriate given that this is a summary of Cisco’s vision on the topics therein. This book is not an official publication and does not have an ISBN assigned. The book will always be free. The opinions expressed in this study guide and its corresponding documentation belong to the author and do not necessarily represent those of Cisco. My only request is that you not distribute this book yourself. Please direct your friends and colleagues to my website where they can download it for free. I wrote this book because I believe that free and open-source software is the way of the future. So too do I believe that the manner in which this book is published represents the future of publishing. I hope this book serves its obviously utility as a technical reference, but also as an inspiration for others to meaningfully contribute to the open-source community.

  • Cisco Nexus 5000 Series Switches
    Data Sheet Cisco Nexus 5000 Series Switches Product Overview The Cisco Nexus™ 5000 Series Switches comprise a family of line-rate, low-latency, lossless 10 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE) switches for data center applications (Figure 1). Figure 1. The Cisco Nexus 5000 Series Includes the Cisco Nexus 5010 Switch and Cisco Nexus 5020 Switch Supporting 10 Gigabit Ethernet and FCoE Today’s data centers are increasingly filled with dense rack-mount and blade servers that host powerful multicore processors. The rapid increase of in-rack computing density, along with the increasing use of virtualization software, combine to push the demand for 10 Gigabit Ethernet and consolidated I/O: applications for which the Cisco Nexus 5000 Series is an excellent match. With low latency, front-to-back cooling, and rear-facing ports, the Cisco Nexus 5000 Series is designed for data centers transitioning to 10 Gigabit Ethernet as well as those ready to deploy a unified fabric that can handle their LAN, SAN, and server clusters, providing networking over a single link (or dual links for redundancy). The switch family, using cut-through architecture, supports line-rate 10 Gigabit Ethernet on all ports while maintaining consistently low latency independent of packet size and services enabled. It supports a set of network technologies known collectively as IEEE Data Center Bridging (DCB) that increases the reliability, efficiency, and scalability of Ethernet networks. These features allow the switches to support multiple traffic classes over a lossless Ethernet fabric, thus enabling consolidation of LAN, SAN, and cluster environments. Its ability to connect FCoE to native Fibre Channel protects existing storage system investments while dramatically simplifying in-rack cabling.
