Overview of this book

Cisco Unified Computer System (UCS) is a powerful solution for modern data centers and is responsible for increasing efficiency and reducing costs. This hands-on guide will take you through deployment in Cisco UCS. Using real-world examples of configuring and deploying Cisco UCS components, we’ll prepare you for the practical deployments of Cisco UCS data center solutions. If you want to develop and enhance your hands-on skills with Cisco UCS solutions, this book is certainly for you. We start by showing you the Cisco UCS equipment options then introduce Cisco UCS Emulator so you can learn and practice deploying Cisco UCS components. We’ll also introduce you to all the areas of UCS solutions through practical configuration examples. Moving on, you’ll explore the Cisco UCS Manager, which is the centralized management interface for Cisco UCS. Once you get to know UCS Manager, you’ll dive deeper into configuring LAN, SAN, identity pools, resource pools, and service profiles for the servers. You’ll also get hands-on with administration topics including backup, restore, user’s roles, and high availability cluster configuration. Finally, you will learn about virtualized networking, third-party integration tools, and testing failure scenarios. By the end of this book, you’ll know everything you need to know to rapidly grow Cisco UCS deployments in the real world.

Preface

Development of Nexus 1000V


N1KV was developed jointly by VMware and Cisco. As such, it is certified by VMware to be compatible with VMware vSphere, vCenter, ESXi, and many other vSphere features.

Virtual Ethernet interfaces

Cisco N1KV, when enabled for VN-Link, operates on the basis of Virtual Ethernet (vEth) interfaces. Once enabled for VN-Link, it maintains network configuration attributes, such as security and statistics for a given virtual interface across mobility events. vEth interfaces are comparable to physical network access ports. A mapping gets created between each vEth interface and the corresponding vNICs on the VM. You may ask me why you would need vEth interfaces. The main advantage of using these is that they can follow vNICs when VMs move to other ESXi hosts. Once you set up a VN-Link on N1KV switches, it enables transparent mobility of VMs across different ESXi hosts and physical access-layer switches, and it does so by virtualizing the network access port with vEth interfaces...
