I suspect your file servers are fine, though given that MogileFS copies
its files into memory (e.g. the get_file_data call) the more memory the better.

The only other comment I would make is to configure your MySQL boxes with Raid 10.
You want high IO rates, particularly if your DB size will be large, and of course
you want the reliability.
