Although I´ve never tested a deployment so big, I´ve had a lot of
problems with 10-20 node deployments. Always one machine or two hangs
booting or deploying, which is pretty annoying; so I can´t have the
cluster deployment completely automatized because I have to watch it to
stop or boot the failing nodes.
