We're a large bookstore. We are purchasing an inventory / POS system. Our inventory will start off with at least 500,000 individual items and grow at a rate of about 50,000 items per year. We will have at least 10 users 4 of which will be on the POS system 9 hours/day. The POS part of the system will handle between 300 to 500 transactions per day. We will will also be receiving, purchasing and returning inventory, another 300 to 500 transactions per day.
My question is is the attached proposed configuration of the server adequate, inadequate or too much for what the software is going to be asked to do.
