This is simply not true.  Much of the rest of the article, which is a
paean to Tandem's systems, is true.  However, one should not overlook
the compromises which Tandem makes in important areas such as "hot spot"
and batch support.  I am aware of IMS systems, BTW, in which 40+ large systems
are coupled via ISC to support a single large application.  Tandem makes
a good product which has enjoyed deserved success in suitable applications.
It is not, however, the answer to every problem.
