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 about the FC switching mode


Similar to LAN connectivity, UCS Fabric Interconnects support two types of switching modes: FC EHM and the FC switching mode. The default switching mode is an end-host mode where UCS appears as a number of hosts attached to the upstream switch. This is also known as N-Port Virtualization (NPV) and requires an NPIV-capable fabric switch for providing the fiber login services.

The other option available is the native FC switching mode where UCS Fabric Interconnect appears as a native FC fabric switch. Switching between FC modes is a disruptive process and hence should be arranged in a scheduled maintenance window.

In order to configure or verify the end-host mode for the Fabric Interconnects, perform the following steps:

  1. Log into UCS Manager.
  2. Click on the Equipment tab in the navigation pane.
  3. In the Equipment tab, click on Fabric Interconnect A (as shown in the following screenshot).
  4. The Status area in the work pane shows the current FC Mode configuration, which...
