We suggest that the RTD server runs on a cabinet system, as these cases provide the necessary scalability in terms of extension slots and main memory. The requirements for a server connecting to a single exchange are given below. If additional exchanges are connected, the requirements for main memory/hard disk space will increase.

Basic Requirements

Free hard disk memory    10 GB (1 GB programs, 7 GB Data, 2 GB Log Files)
Main Memory                      4 GB
Network                               100/1000 Mbit

Remarks:
The RTD Architecture takes full advantage of multiprocessor systems. The processing load is distributed over several processes. In multiprocessor environments the operating system ensures that the processes are being executed on all available CPUs.

Sizing of clients in general is much more complicated. Different users have different requirements. We have taken these different requirements into account by using the user profiles described before. High CPU performance is required by the RTD client.

Multiprocessor Systems

Due to the internal structure of the RTD system which spreads different functionalities over several processes, the client benefits from multiprocessor platforms. In this respect it is a multi-threaded application but each thread runs within a separate process. In this way the operating system is able to distribute the load among several processors.

Basic Requirements

Free hard disk memory    200 MB
RAM                                      min. 2 GB
Graphics Adapter               Latest generation graphics adapter 
Network                               100/1000 Mbit
