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

Nexus 1000V components


N1KV consists of VSMs and VEMs. While VEMs are software elements that reside inside the hypervisor, running as a part of the VMware ESXi kernel. The VEM acts like a line card to VSM and provides packet forwarding and other functions for virtual machines. Whereas VSM is deployed as a virtual appliance and provides control to manage multiple VEMs and virtual machine traffic steering. Have a look at the following diagram for more details:

The highlighted components in the preceding diagram are explained in the following sections.

The Virtual Ethernet Module

The Virtual Ethernet Module (VEM) runs as a part of the VMware ESXi kernel. It uses the VMware vNetwork Distributed Switch (VDS) API to provide advanced networking capabilities to VMs.

The VEM provides advanced networking functions, such as QoS, security features, and monitoring features, by taking configuration information from the VSM.

The Virtual Supervisor Module

Multiple VEMs create a single logical switch layer to...
