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

Single Fibre Channel failure and recovery on Fabric Interconnects


In virtualized environments, SAN connectivity is very crucial for hypervisors as a shared SAN is a critical component for advanced virtualization features, such as migrating and then running virtual machines between different hosts. A problem with the connectivity of the SAN array can also cause issues with the SAN boot.

SAN could be connected to Fabric Interconnects directly or through a northbound Nexus, MDS, or third-party switch. Proper connectivity between Fabric Interconnects and SAN storage processors or Fabric Interconnects and SAN fabric switches is necessary. SAN connectivity is also configured as redundant. However, unlike Ethernet, where a northbound vPC that is using a cross-switch connection can protect against a complete switch failure, the connectivity between SAN switches and Fabric Interconnects can only be a straight connection. It is, however, possible to create a Fibre Channel port channel for protection...
