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

Server link to Fabric Interconnect failure and recovery


For blade server and Fabric Interconnect connectivity, there are two connections involved between the server mezzanine card, IOM backplane ports, IOM fabric ports, and Fabric Interconnect server ports. These connections are as follows:

  • The connection between the blade server mezzanine card and IOM backplane port that connects the blade server to the IOM in the chassis
  • The connection between the IOM fabric port and Fabric Interconnect server port that connects the IOM in the chassis to the Fabric Interconnect

Connectivity failure can happen due to a mezzanine card, IOM ports, or Fabric Interconnect server ports. We will now look at different port failure scenarios.

Identifying a mezzanine adapter failure

The first requirement is to identify and isolate the source of the issue, which can be the server mezzanine card, IOM card ports, or Fabric Interconnect server ports. To determine that the issue is with the server mezzanine card and not with...
