+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.
