Today computer networks are everywhere and involved in all aspects of our lives. The ubiquity of these networks allows us to use services and products which perform the majority of their processing in a distant data center. Activities of end users are becoming increasingly dependent on IP-based networks with many applications even requiring a continuous and stable internet connection. It is the key that IP networks continue to provide a reliable connection between end users and the data center, even in case of equipment failure.

The purpose of this thesis is to build an IP network infrastructure for use in a corporate environment that is both fast and provides a redundant connection between the end users and the data center, in order to meet requirements of the business. The method is demonstrated which integrates the user authentication portion of the network with data center network such that redundancy is guaranteed in layers 2 and 3 of the OSI model. Various parts of the network are presented and the method for building a high speed and redundant data center network using Cisco Nexus hardware is demonstrated. Additionally, various types of communication and services are discussed within a data center including Ethernet and Storage Area Networks (SAN).

The goal of this thesis is to build a network where a single interface is used to transmit both Ethernet and SAN traffic. The Fibre Channel over Ethernet (FCoE) protocol and its configuration on the Cisco Nexus is demonstrated. Configuration of the data center's computing infrastructure which runs on the VMWare ESXi virtualization platform and the design of interoperation with the network through FCoE is also presented is this thesis.

The majority of the techniques presented in this thesis can be readily implemented in order to markedly increase the reliability and uptime of networks; improving the overall satisfaction of the end users.
