A little help with school

I am currently working on a project for my school class in which we need to "review an actual product that can be used to help support a production
environment. It must be either:
• a commercially available software or hardware product from a known vendor
• a currently available open source software package with source code presently available."
Some tech already chosen are products such as VMWare, Acronis, ERLOGIX, and XSan 2.
My request is for some other interesting technologies that some of you might know of that I can research myself.
Thanks

What about Subversion?

It is currently used to manage the development of the iPhone Mormon Channel app.
