While the cache is MF DASD (which gives it great performance when writing and
reading from cache), CA-Vtape now has the ability to be offloaded to cheaper

CA VTape is a software solution that uses any disk that you happen to
have. The down side of this type of solution is the increased CPU usage
due to it being a software solution instead of a hardware solution, like
the TS7720, that uses private disk in behind the scenes.

What???
CA VTAPE is from software being sold by CA. DS8800 is a DASD box being
sold by IBM.
CA VTAPE works on any mainframe DASD.
I don't know what does it mean "work on regular MF".

So Question 1 and 2 get the same answer. Any given Logical partiton can
have some logical CPs ready to run, and pther logical CPs in the WAIT

You don't have to wait for it, you can also force it. Amdahl's MDF did

To dispatch entire LPARs would be waiting for 2n ducks to line up in a

I was going to reply, that your view on pr/sm was incorrect: pr/sm does
not dispatch entire LPARs, but individual processors, if the LPAR's
weight allows it. But
