In an effort to remain competitive in the virtualization market, VMWare is giving away its GSX Server product, while hoping that customers will want to upgrade to the company’s more powerful ESX Server.
GSX runs on a “host” Windows or Linux operating system and then lets “guest” operating systems run atop it in compartments called virtual machines. The higher-end ESX product, in contrast, needs no host and runs below the operating system layer.

Today, GSX costs $1,400 for dual-processor servers and $2,800 for more powerful machines. ESX, while more expensive, permits more sophisticated features such as VMotion, which lets one running operating system be moved from one server to another while it’s still running.
