where does one buy a 600VDC 10kW power supply?

Parallel is no better than series. Consider series or parallel configuration only if such mode of operation is "officially supported". What about using two different supplies - one for max voltage and another for max current tests?

Keysight call it Autoranging. They have a 10kw 750v power supply. Model N8929a

Yes all of the decent high power supplies have a master/slave mode with the comms ports so that one supply will control a bank of similar supplies. But with parallel connection there are no insulation issues. If you start connecting in series the higher ones in the stack can be well beyond the insulation grade. At these voltages i doubt they are really meant to be put in series at all.
Berni:
Some large rack supplies do have features to automatically link them together and make them track, yes long chains of 4 supplies in series are likely not supported, but its pretty common to be able to make them track together for making +/- split rails. Especially when both supplies are identical models rather than two different ones (That way a more powerful one couldn't force current trough the weaker one). If the particular model supports series operation the manual will mention it and show how to wire it up for it.

Sorry didn't know big supplies are mostly power limited. I never worked with PSUs quite this big and the biggest PSU i own is only about 2kW. In the low kW range the supplies i have seen have no power limit and can do both max current and voltage simultaneously, or do have a power limit but can only be reached with about ~40% or more of the max voltage before it hits the current limit.

Simon:
All of the rack supplies can be linked. Rather than buy massive ones you can just stack as many as you need or up to a specified maximum as explained in the manual yes.
