This book is intended for professionals responsible for Cisco UCS deployments, which include systems, network, and storage administrators. Readers should have basic knowledge of the server's architecture, network, and storage technologies. Although not necessary, familiarity with virtualization technologies is also recommended because a majority of real-world UCS deployments run virtualized loads. Even though UCS Fabric Interconnects running UCS Manager are based on the Nexus platform, knowledge of Nexus OS is not necessary, because the majority of the management tasks are handled in the graphical user interface, with very few exceptions using the CLI.
