Re: Explaining single level store to non i people

Solid State DIsk has been "just around the corner" for a couple of
decades. I remember reading that rotating disks would be replaces by SSD
while I was in college in the early 1980's.

Until I read that Wikipedia entry I hadn't realized just how far ahead
the thinking of the IBM folks was when SLS was devised. Only now some
40 years later has solid state storage reached a point where finally
this is on the verge of becoming reality.

"IBM?s design of the single-level store was originally conceived in
the late 1970s as a way to build a transitional implementation to
computers with 100% solid state memory. The thinking at the time was
that disk drives would become obsolete, and would be replaced entirely
with some form of solid state memory."

Jon: This is the first I'd ever heard of this as a rationale for
single-level store in the design of the S/38. If that was true, it would
be an incredible case of bad planning. What business can justify a plan
based on some questionable technology that won't happen for at least 40
years?
