*Forecasting Shell Server*
The forecasting shell server is the server for execution of forecast runs. It contains the modelling software and it's operation is controlled by the Master Controller
* advised internal memory and CPU: Minimum 1 GB RAM and 1 one CPU core per FSS instance, CPU typically Intel Xeon 2.33 GHz or equivalent. 
* operating system: Windows 2000/XP/2003, Linux RedHat/CentOS/SUSE contains modelling software (incl. licenses), OS usually dependent on 3rd party modules and modelling software 
* amount needed: Minimum 2, more depends on computational load 

*Master Controller Server*
The master controller organises task traffic and scheduling  
* advised internal memory and CPU: 800 MB RAM per MC instance. CPU typically Intel Xeon 2.33 GHz or equivalent.  
* operating system: Linux RedHat/CentOS/SUSE, Windows 2000/2003. Other Unix-like operating systems possible (e.g. HP-UX, Solaris), as long as there is a Sun JDK 1.5 (and 1.6 in the near future) available for the OS. JBoss 4.0.2 or Weblogic 8.1 SP3 (may be on a separate server) 
* amount needed: 1 or 2  

*Central Database*
This is the central data repository, linked to the master controller. We support Oracle 10g (back to Oracle 9 supported), PostgreSQL 8.2, MS SQLServer 2000/2005. This list is not exhaustive, so contact us if you are thinking of using a different database or a different type.
* advised internal memory and CPU: See Database vendor requirements. Typically 1 GB RAM per DB instance and CPU Intel Xeon 2.33 GHz or equivalent.
* The database instance(s) can be a hosted on an existing database server or cluster. 
* uses 1 instance for each Master controller  

*Operator clients*
The operator client (Gui) is the user end - thick client, multiplied by copying. The operator client uses a _local datastore_, usually MsAccess or the open source Firebird db. 
* advised internal memory and CPU: none, normal pc  
* operating system: Windows 2000/XP/2003, Linux RedHat/CentOS/SUSE  
* amount needed: as many as there are clients
* possibilities to use under CITRIX available 

*Webserver*
The webserver is an optional server that hosts and distributes the webpages generated by Delft-FEWS. Hardware requirements depend on the intended use.
