RedHat Enterprise?

[pluk]

Which version is compatble to DA?

Red Hat Enterprise Linux AS
Red Hat Enterprise Linux ES
Red Hat Enterprise Linux WS
Red Hat Desktop

Are they all the same with just different optimizations?

The desktop version is most likely not best for a webserver, the other versions vary on supported platforms.
