Wants and Needs! How to build this idea.

[happz]

Hello all. Here is what I want to accomplish and my time frame is 12 to 24 months to prefect. I want build a Linux server(s) with a massive amount of hard drive space and RAM so that I can provide VPS to clients to run their own virtual servers-resell accounts. I need to know the best hardware i.e. server (dell(s) maybe?) and technology to use. My scope on this project is to first build this on a small scale and then take it up a notch. Small meaning on a dsl line. I would also need to know best practice for backups and high availability.

thanks,
happz
