My mistake...it was my impression that z/Architecture is very similar
to that of ESA/390, more so than the other evolutionary steps in the
S/360->S/390 family architectures.

Umm, I have
to disagree with you there...the machines in question are
indeed of a mainframe architecture, and some IBMers were calling them
"servers" many years before the zSeries was even an itch in IBM's
pants.
That's a mighty big itch. Regardless
of what industry buzzwords the marketroids are trying to
take advantage of...those machines implement the S/390 architecture,
which is a mainframe architecture descended from mainframe
architectures.
Actually, those machines don't implement ESA/390. They implement z/Arch.
But z/Arch definitely evolved from ESA/390 R4.
