As a general rule, Lustre performs very well with large files and linear IO patterns, which seems to match your usage. You can get very good scaling (nearly linear with each OST) and a single client+server can saturate a GigE network (110MB/s). Configuring Lustre 1.6 isn't much different than NFS. Format each server, mount them, then mount the clients.
