Number of devices

I am working on an application which is written in C++ on SunOS 5.9.

The application uses oracle 9i and CORBA . The application is written in such a way that it talks to 400 devices simultaneously .

My question is , if the number of devices are to be increased 4 to 5 folds ( i.e., nealry 2000 ) what are the things that I should look into at the beginning . How do I go about resolving this problem.

Can you please give me some basic ideas as I am new to this kind of problem.

Thanks.
