+ - Report: Mainframe is a Perfect Functional Superset-> 1

Submitted by BBCWatcher
BBCWatcher (900486) writes "Germany's Wilhelm Schickard Institut fur Informatik has just published a paper on "System z and z/OS Unique Characteristics," and here's its thought-provoking opener: "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." The report provides comparisons (to the extent possible) between 40+ mainframe capabilities and other servers' capabilities, with lots of references. Although quite technical, the paper is approachable. (Sun's mainframe-critical ad reprinted in the report is especially amusing given recent history.) There's also this closing prediction: "We assume that present [mainframe] technologies...will become available on other server platforms within the next 10 years. We also assume mainframes will have introduced new not yet identified technologies [during] this time, and that the size of the technology gap will remain roughly the same. During the last 30-40 years this has been the case, and the driving forces have not changed." IBM says there's a new mainframe model coming this year, so we'll see more of the leading edge soon."

  • Being stuffed to the gills with complex technologies is not the same as being advanced or "leading edge". A lot of those technologies will remain limited to mainframes, and many will probably even be eliminated there because they are just not useful.
