I'm not sure if this applies to your configuration, but for a few years I
ran a BA23 (or maybe even two BA23s) with a KDA50.
So it at least *should* work. You may want to check that you don't have the
somewhat dodgy power cable that is known to be susceptible to overheating.
Other than that, I can't imagine any problem.
I don't recall whether I had the correct back panel connectors. If you
don't you need to remember that from controller to drive you need an odd
number of cables (iirc).

Thanks Andreas, Ed Groenenberg has been helpfully guiding me through
the thicket that is DEC SDI, and it appears I need the KDA50-Q (QBUS
DEC SDI controller set - two quad boards connected via top of card
ribbons) or its equivalent.
If I interpret the manual correctly the two modules are M7165 SDI
module and M7164 processor module. These modules are connected via a
40-pin flat cable and a 50-pin flat cable. This pair needs 68W and the
manual suggests a H3490 expansion bay, but is this for the additional
power or just the slot capacity or both?
I'm a little surprised/impressed to see that DEC SDI can run to
50-foot cables between host and device.
As someone who has barely tinkered with DEC SCSI and never used MSCP
(does TK70 count?) DEC SDI seems quite exotic.
