3-phase is not needed for the z's. If the DS8000 is only partially
filled, it's happy with single-phase also.
I have replaced the three-phase cable ends with single phase 220v ends
on several DS8000s.

Basically, running FBA storage restricts you to running z/VM and z/VSE, and
possibly z/Linux (I've never run it on FBA, but there's no particular
reason it wouldn't work). z/OS requires CKD DASD.
Learning experience? Absolutely!
I want to get a z/Series myself, but there's a tradeoff there...in
particular, I don't think I could manage 3-phase power.

Hello. I am a US high school student who is seriously considering
acquiring a z114 mainframe. I have found a listing selling one for a price
that I think is reasonable, and I have determined that I can meet the
space, transportation and power requirements for the machine. I did however
have one question before I continued. I know in Connor Krukosky's talk, his
biggest issue was finding DASD for the machine. I have looked, and it
appears that proper ficon DASD is still rare. My situation is not quite as
significant as Connor's , as my machine has SCSI IPL as a native feature.
Despite this, I wanted to know if anyone here could give some advice on the
topic. Would the machine still provide a good learning experience with just
FBA storage?
Thank you for any information that you can provide
