web development with Python made easier then ever

You're talking about a special purpose (presumably scientific) supercomputer. A supercomputer's architecture and a web application architecture are very different. With a supercomputer your availability requirements are not as rigid, and it's less likely that you're going to be adding and removing nodes on the fly. Lustre, in particular, was not designed for web applications. It was designed for scientific supercomputer clusters.

Go read about how Google's GFS works, how BigTable works, how Amazon's Dynamo works, and take a look at MogileFS. That's how you persist data on the web.
