Is it just me or does one need to be in 100% concentration just to understand
what this means.
A simple decision flowchart would have made it a lot easier on the common man's
brain.

You have data set encryption. "Pervasive encryption" is a strategy, not a
product or feature. And it's not that *any* data
A question out of pure curiosity: In the z16 version of PoOP (SA22-7832-13)
there is mention in the "Summary of Changes in Fourteenth Edition" section of
this enhancement:
Mapped-I/O-addressing facility [PCI ONLY]
I can find no other reference to such a facility anywhere in that document.

IBM has been using PCI and PCIe internally for some time.
Memory-mapped I/O is a process whereby an address generated by the CPU os
translated to an address in an I/O device connected to the CPU, in this case an
I/O device on a PCIe bus.
Does anybody use that feature other than Linux on Z and

If I were to guess, I think this is plumbing related to the new (?) capability

Also, what's "CP support of Linux on Z"?

Apart from the "embedded" DS8K you've mentioned.
Thank you!

I don't think IBM ever offered any physical tape drives directly connected to
z/OS, i.e. physical tape drives with FICON or ESCON ports on them. The IBM
