I don't think that the writer of the document (Dr. Rubin) compares apples to apples. IBM mainframe does not operate the network (DNS, DHCP, AD, email servers and many other base services). there are some tens of servers that has no comparable service in the mainframe world. The mainframe, from this point of view, is just another server, and the comparison should compare mainframe applications vs alternatives (re-hosting, rewrite), or the other hand - moving a server application into the mainframe.
Rubin asked the best question of all. Does the presence of mainframe(s) at the heart of an IT infrastructure make a business more efficient and save them money? No matter which industry he surveyed, the answer was a resounding yes. The only difference was by how much.
There are many questions to be asked about IBM marketing strategy, most has been asked in this thread. Have you even thought why does Cobol program runs much faster on wintel then a mainframe? Why is sorting much efficient on wintel?
A URL or official reference would be useful to help justify these assertions. -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 http://www.phoenixsoftware.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
