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

Configuring high availability clustering


A UCS Fabric Interconnects pair can be configured in a high availability cluster. In the cluster configuration, FIs create a primary secondary affiliation to control data traffic flow whereas the data plane forwards simultaneously on both Fabric Interconnects. This means cluster control traffic flow is controlled only by the primary node whereas network data can flow through both FIs under normal conditions. Fabric Interconnects are connected through dedicated Gigabit Ethernet UTP copper ports, which do not participate in the data plane. These interfaces are marked as L1 and L2. L1 of one Fabric Interconnect should be connected to the L1 of the other Fabric Interconnect and similarly L2 should be connected to L2 of the peer. These links carry cluster heartbeat traffic.

High availability configuration requires three IP addresses. Both Fabric Interconnects require an IP address each, and the third IP address is the cluster IP for the management that...
