***Update***
I ordered one, and it arrived Friday. Its installed and running fine in my Dell R710 server running ESXi 6.7. It gave a warning that it was being installed on an unsupported OS, but allowed the install to continue. Here is the current status:

I am not sure about the message regarding unactivated firmware, the system has been rebooted a few times, and this message still appears. Anyone familiar with that?
