Many people still associate mainframes with obsolete technology. Surprisingly, the opposite is true. Mainframes feature many hardware, software, and system integration technologies, that are either not at all, or only in an elementary form, available on other server platforms. On the other hand, we know of no advanced server features which are not available on mainframes. This paper lists some 40 advanced mainframe technologies. There is a short description of each item together with a literature reference for more information
