I’ve got a sc220 (24x2.5) and a md12 (24x3.5) (reports as 1240 anyway) (24bay) Shelf connected to two dual h300 per r620.
Regarding the md1200 emms in an md3200, it won't just work. Here are a couple threads explaining that the backplane actually has a setting that needs changed for it to work as you expect.

So I've tried this on my own and without the software running on each respective controller being aware of the SAS pathing to the disk, there is no connection that I could get going. The reason that diagram works is due to the Compellent controller and software magic. I wasn't even able to get the Compellent branded LSI controller to recognize the drive tray.
XON/XOFF is required or it simply will not respond... but Putty does this by default and it does no parity, 8 data bits, 1 stop bit by default so as long as you put in 38400 and the correct serial port, you should be fine. In fact, it can get to a point where you need to power cycle the shelf if you hit it with too much nonsense.
asd_offset command returns:and
_ecc returns the following (after I _ecc clear this eventually comes back upon next reboot):I updated the firmware to 106 prior to this happening.

exit4kn disks DO work in an MD1200 as long as the controller the MD1200 is plugged into supports 4kn disks. I had 4 Seagate ST10000NM0206 working in one MD 1200 for a few months before I moved them to a different server. I also have 3 new (new to me) MD1200 each with 11 ST8000NM0065 in them. They are working no problem. Using Dell Perc h830 controllers in Poweredge R730 and T630 servers
