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.

Nexus 1000v components


N1KV consists of VSMs and VEMs. While VEMs are software elements that reside inside the hypervisor, running as a part of the VMware ESXi kernel, the VSM is deployed as a virtual appliance. Have a look at the following figure for more details:

The highlighted components in the preceding figure are explained in the following sections.

The Virtual Ethernet Module

The VEM runs as a part of the VMware ESXi kernel. It uses the VMware vNetwork Distributed Switch (vDS) API to provide advanced networking capabilities to VMs.

The VEM provides advanced networking functions, such as Quality of Service (QoS), security features, and monitoring features by taking configuration information from the VSM.

The Virtual Supervisor Module

Multiple VEMs create a single logical switch layer to the VSM. The VSM maintains configuration and pushes down the configuration to the VEMs. The administrator has the ability to define configurations on all VEMs being managed by the VSM from a single interface...
