Ahem, yeah you need to define your goal, requirements and budget for this setup. What do have in the way of network and storage gear etc. What vmware product are you thinking of using? You can setup a cluster of two hosts. Shared storage and vmware licensing will likely be your biggest spends. I'd hate to advocate an inferior product but HyperV may be a cheaper way to go but I'm a little stale on what consumer level products vmware produces anymore as all my work is in vsphere.
Well my goal is for home use. I am using Cisco switches and the everyday happy home owner router from your local cable provider, but if I decide to make this a larger scale network I will purchase a Cisco 2821 router. Like I said in the previous post I am using Dell servers with Redhat installed and I am wondering if it would be beneficial to run VMware and if so what flavor of VMWare would be the best for private home use?
In this case ESXi might be the right product for you. Since this is installed directly on the hardware (i.e. a Type 1 Hypervisor) make sure you check your hardware is compatible (e.g. RAID Controller, Network adapters, ...). See VMware Compatibility Guide
