As of the original writing of the webpage \ how-to. VMWare server was the best virtualization server solution around. Now days, if you’re planning a VMWare server or Hypervisor there are many more options, and in my opinion, better options.
My first vote would be 64-bit Proxmox ( http://proxmox.com )
This is a virtualization solution built on Debian Linux. Just use the Proxmox iso from their website instead of the Debian iso from my website. This way your initial format \ installation not only installs Debian Linux, but it also installs and configures Proxmox, KVM and LVM for you (this is huge, an expert install right out of the box). Once the install completes, you can then follow my guide. Giving you even more control and functionality out of your Proxmox server. It’s perfect for the do-it-yourself’ers that know Linux commands.
My second choice is a 64-bit VMWare product called ESXi, (you might hear rumors that ESXi expires after 60 days, that is not true, you just have to enter your free serial number they emailed you) and third is 64-bit Citrix XenServer. These are incredible products, but they are canned hypervisors, meaning that’s all the server can do, your limited on what you can change \ customize. Whereas Proxmox is wide open, and fully customizable. All (3) are very very strong and very very good.
