This document describes a way to virtualise the number of network servers that are required for the operation of a large campus network. These servers provide services, including DHCP, DNS, VPN, email, network monitoring, and radius. Most of these services are so important that the network must operate two or more of them at the same time, and this leads to an increase in the number of servers. Usually, these services do not require a great deal of computing power, indicating an excellent opportunity to use virtualisation The document is focused on the different requirements to be considered when choosing the appropriate hardware for the job, with emphasis on the price/performance ratio, while maintaining all the benefits of the Vmware vSphere system, which was selected as the virtualisation platform. The document also describes practical experience and the pitfalls that may be encountered during the installation of the system. It describes the configuration of network devices, the iSCSI storage, and the VMware vSphere hypervisors. The conclusion summarises the results and explains the benefits of virtualisation for the campus network.
