As you may know, Sun finally released the new Niagara processor. Sun Sim Datacenter let you simulate a datacenter with whatever servers and workloads targets you want to compare monthly costs. I don't care about (mostly because I don't understand the throughput and all those other weird server side thingies). I'm more interested in the application itself. It's a cool looking WebStart Swing application. You can give it a try or take a look at the screenshots below.
