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

Indicating a status with Beacon LEDs


The UCS chassis and components have different colored LEDs and flashing patterns. Looking at the LED's status can also help identify various issues. All UCS components, including the chassis, IOMs, power supplies, fan units, blade servers, and Fabric Interconnects have different LED indicators that can provide information about the component's location, faults, or operational status. Locator LEDs are blue in color, operational status LEDs are usually green or a blinking green color, and faults are identified with solid, amber-colored LEDs. The UCS chassis and blade servers have some buttons as well; these can be pushed to turn the locator LED on/off.

The following table describes how to interpret the LED indicators on various UCS components:

LED status

Interpretation

Off

Not connected. No power.

Green

Normal operation.

Blinking green

Normal traffic activity.

Amber

Booting up, then running diagnostics or a minor temperature alarm.

Blinking amber

Failed component or...
