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

Learning to create a UUID pool


A UUID is a 128-bit number assigned to every compute node on a network to identify the compute node globally. The UUID is denoted as 32 hexadecimal numbers. In the Cisco UCSM, a server UUID can be generated using the UUID suffix pool. The UCSM software generates a unique prefix to ensure that the generated compute node UUID is unique.

Operating systems including hypervisors and some applications may leverage UUID number binding. The UUIDs generated with a resource pool are portable. In case of a catastrophic failure of the compute node, the pooled UUID assigned through a service profile can be easily transferred to a replacement compute node without going through complex firmware upgrades.

The following are the steps to create UUIDs for blade servers:

  1. Log in to UCSM.
  2. Click on the Servers tab in the navigation pane.
  3. Click on the Pools tab and expand root.
  4. Right-click on UUID Suffix Pools, and click on Create UUID Suffix Pool, as shown in the following screenshot:
