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.

Configuring southbound connectivity to IOMs


Each Fabric Interconnect is connected to IOMs in the UCS chassis which provides connectivity to each blade server. Internal connectivity from blade servers to IOMs is transparently provided by UCS Manager using 10BASE-KR Ethernet standard for backplane implementations and there is no configuration required.

Connectivity between Fabric Interconnect server ports and IOMs is required to be configured. Each IOM module, when connected with the Fabric Interconnect server port, behaves as a line card to Fabric Interconnect, hence IOMs should never be cross-connected to the Fabric Interconnect. Each IOM is connected directly to a single Fabric Interconnect using the following cabling configuration:

  • Cisco UCS 2100 IOM: Possible connections are 1, 2, or 4 as there are only 4 ports

  • Cisco UCS 2200 IOM: Possible connections are 1, 2, 4, or 8 depending on the model, because 2204 provides 4 ports and 2208 provides 8 ports

With UCS 2100 IOMs and older UCS Manager...
