We have APC UPSes (supported Model).

But after the ups is connected for several days strange things happen.

If you click an Status - Devices you dont get a status but the GUI freezes for several minutes.

We have several storages with that constellation and it is all the same.

open-e says there is no problem but we have it.

I already regret that we didnt get EQUALLOGIC instead!!!!

Conclusion: TRY and good luck.
