No, all I have seen was no more than 96K per box.

With 96K sub and 100 Subscriber/s setup rate you'll need 16 Minutes to
be back in service after service downtime for whatever reason. And
thats under best conditions of your whole network.
There is no good reason for these large systems although we have
done that in the past with the SEs.
The SE is doing fine - But suddenly you start thinking about RADIUS
Server network latency and using multiple ports on client and server.

That's important element you've just mentioned.<br>
Radius - right after a crash it is really heavy loaded. At the
moment we have ~15k subscribers (CLIPS/PPPoE, mixed)<br>
and we decided to have Radius database kept on SSD.<br>
Before in heavy load situations database was not able to respond
quickly enough to radius (freeRadius, mySQL).<br>
Now, with SSD it is much faster and all the recovery after eventual
linecard crash is much faster.<br>
