This guide does not provide information about hardware requirements. Please check the Microsoft website for hardware requirements for the relevant environment.
Please keep these points in mind when making decisions on hardware purchases. System performance of each PC and server depends on the following:
the processing power
how computers are configured, and what Windows features are installed
the number of applications running, including anti-virus utilities, backup utilities, screen savers, and power savers
the number of users in Opera and the amount of Opera data throughput and the number of locations where Opera is used
whether the Opera Client installation is used on the file server, adding an additional load on the server.
