How many IEDs can be connected to the wincc OA Server ?

I know that wincc OA has no limit on the number of device connection.
In my project, a total of about 300 IEDs will be connected to the OA redundant server.
But, I read about 61850 client in OA Help and found the following limitations.
"The driver can establish connection up to a maximum of 200 devices."
Does that mean that there is only a maximum of 200 IED connections per OA server? Or does it mean that up to 200 units can be connected per one 61850 driver?
