mss/3850 provided simulated 3330s (icebergs) staged from tape cartridges.
originally had real 3330 drives for staging the simulated 3330 drives.
mss/3850 had two modes ... staging a full cartridge or staging six 3330
cylinders (at a time). i/o done to a simulated 3330 address could get
back a unit check with "cylinder fault" in the sense data ... prompting
for the operating system to stage the appropriate data from tape to disk.
later there was a mss/3850 option that would use 3350 drives for staging
the simulated 3330 data.
later during the ADSTAR period in san jose ... there was the C-STAR
project which was working on a new disk controller that was to suppose
to provide equivalent function to the STK (iceberg/9200, different
project, different vendor, same name) controller that had virtualized
disks (compression and various other functions) ... as well as raid
support. Slightly later, IBM licensed and marketed the STK iceberg/9200
controller. the stk iceberg was some 25 years after the 3330 iceberg.

Ah yes. I wrote the training courses for the product back
in 74/75. A one day overview and a three day installation
and planning course.
I left IBM in 1975 to start my own training business. After
struggling for about a year I called my old manager back to
see how IBM felt about re-hiring ex-IBMers. He said "Wait,
don't do anything yet." In a couple of days I had a call
from the folks at San Jose asking what I would charge to
develop an operations course for the MSS. I quoted a price
and they accepted with no bargaining.
That was IBM's way of saying "We want you to succeed." On
the other hand, it was made clear this was a one time deal.
I produced the course, and they used it, but for me the
important part was that enabled me to keep my business
going.
Kind regards,
