I, as well as two other students, are creating curriculum for a new datacenter course at our university. We have 16 Sun servers that are several years old with decent specs (2x Dual-Core AMD Opterons with 4 or 8GB RAM) and ESXi 5.0 installed that we want to setup as a small, test datacenter environment for students to use.
An example of a task the students would go tackle: configuration of LAMP servers.
Students would VPN into the local network to then access their virtual machine of Ubuntu.
VMware's documentation is one of the most egregious I have worked with. We have the idea to run a Windows Server 2008 R2 VM that would then run vCenter. The second VM would run Ubuntu 12.04 with OpenVPN. I have seen several recommendations to build a SAN from one of the machines to host the OSs. Does anyone have experience setting something up that is similar?
