The system will consist of 77 sites with between 20 and 200 users per site for a total user base of 1800. All servers and databases will be in a central data center with each site connected to the data center by a T1. we may want to consider separate databases with replication to support batch vs realtime transactions. Our total server count must be less than 30, hopefully less than 20 if possible. This would include Runtime Application servers as well as SQL Servers. Anyone have any hardware configuration suggestions for running a very large very transaction oriented system?
