There is no technical difference between RHEL AS and RHEL ES.  The 
difference is in what Red Hat will or will not support as far as the 
number of CPUs and the amount of RAM in a system.  RHEL 4 ES and RHEL 4 
AS can both support the hardware listed for RHEL AS.  The difference is 
that if you call Red Hat and have support for RHEL ES and you have more 
than 2 physical processors or more than 16 GB of RAM they will tell you 
that you are running an unsupported configuration.  If you are running 
RHEL 4 AS with the same configuration, you are running a supported 

These issues do not plague CentOS.  You can expect CentOS 4 to run 
hardware up to the same configuration of RHEL 4 AS.
