<p>+1 for Puppet. I manage only around 20 servers all running a mix of CentOS 5.6 and CentOS 6 very well with Puppet. The initial configuration and understanding for it is daunting but WELL worth it in the end. Also for system provisioning ( kickstart and pxe) look at Foreman, which uses Puppet after initial installation.</p>
