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

Port channel uplink failure and recovery on Fabric Interconnects


Fabric Interconnects can connect to northbound Nexus switches either directly or using a port channel/vPC. Port channel configuration, which not only load-balances bandwidth utilization but also avoids unnecessary reconvergence in the case of partial link failures, is recommended as multiple uplink ports can be aggregated.

Use the following procedure to verify northbound port channel configuration and the operational state:

  1. Log in to UCS Manager.
  2. Click on the LAN tab in the navigation pane.
  3. In the LAN Cloud tab, expand Fabric A and Port Channels.
  4. In the work pane, the Status of Port Channels is shown in the General tab as follows:
  1. The Ports tab shows member ports and the Faults tab shows any faults as shown in the following screenshot:

The following screenshot shows the error message that is displayed when a port channel cannot be brought up due to a mismatch in speed between the Fabric Interconnects and uplink Nexus ports:
