“The joke used to be that IBM’s mainframes were the useless
dinosaurs of computing. None of IBM’s rivals are laughing now. With
Linux gaining popularity on IBM’s zSeries, the mainframe is making
a strong comeback.“This really isn’t news though. In 2001, 11% of IBM’s new
mainframes were being sold with Linux under the hood. Today,
according to Joan Mestzeler, IBM’s director of enterprise solutions

acceptance. Holger Dryoff, head of SuSE’s American operations, says
that SuSE’s mainframe Linux; is accounting for almost 20% of SuSE’s
North American business. Other Linux companies–Red Hat and
Turbolinux–support the IBM’s zSeries, but SuSE is the leading
mainframe Linux vendor…”
