Implementing Cisco UCS Solutions

Overview of this book

Cisco Unified Computing System(UCS) provides unique features for the contemporary data centres. Cisco UCS is a unified solution that consolidates computing, network and storage connectivity components along-with centralized management. Cisco UCS reduces TCO and improves scalability and flexibility. Stateless computing blade server's design simplifies the troubleshooting, and Cisco-patented extended memory technology provides higher virtualized servers consolidation results. A hands-on guide to take you through deployment in Cisco UCS. With real-world examples for configuring and deploying Cisco UCS components, this book will prepare you for the practical deployments of Cisco UCS data centre solutions. If you want to learn and enhance your hands-on skills with Cisco UCS solutions, this book is certainly for you. Starting with the description of Cisco UCS equipment options, this hands-on guide then introduces Cisco UCS Emulator which is an excellent resource to practically learn Cisco UCS components' deployment. You will also be introduced to all areas of UCS solutions with practical configuration examples. You will also discover the Cisco UCS Manager, which is the centralized management interface for Cisco UCS. Once you get to know UCS Manager, the book dives deeper into configuring LAN, SAN, identity pools, resource pools, and service profiles for the servers. The book also presents other administration topics including Backup, Restore, user's roles, and high availability cluster configuration. Finally, you will learn about virtualized networking, 3rd party integration tools and testing failure scenarios. You will learn everything you need to know for the rapidly growing Cisco UCS deployments in the real-world.

Chapter 11. Cisco UCS Failure Scenarios Testing

In this chapter, we will walk through the different types of failure scenarios that can occur in Cisco UCS. UCS solution components have excellent redundancy for critical equipment such as chassis and Fabric Interconnects. However, in an unexpected situation such as a physical component's failure, we should be able to identify the failed component and possibly conduct some troubleshooting before contacting Cisco TAC. The most common equipment that fails for the UCS are chassis/Fabric Interconnect power supplies, FAN units, IOMs and SFPs for both IOMs, and Fabric Interconnect ports. If proper failover is configured for the network adapters (vNICs) and proper connectivity is configured for the storage adapters (vHBAs), the majority of single component failures do not result in data or management traffic disruption.

UCS failures may also be related to configuration issues, firmware mismatches, temperature issues due to air flow obstruction, and...
