ABSTRACT
This chapter discusses hardware issues that data center managers must consider as part of a well-thought-out plan for moving to client/server computing. Data center managers are responsible for providing senior management with accurate information about the cost of moving to client/server computing. Client/server computing can ultimately be less costly, but moving to a client/server environment requires a considerable up-front investment. Data center managers must explore the use of techniques for forecasting hardware capacity requirements in client/server environments. Hardware is the largest single expense in the move to client/server computing. This hardware includes: file servers, workstations, file backup equipment and printers. A client/server system is often linked to a mainframe, and this connection requires such equipment as bridges, routers, and gateways. Although the cost of client/server hardware is less than the price of a mainframe with comparable processing power, the total cost of a transition to client/server processing is substantial.
