Installation and Maintenance
Hardware Requirements
The necessary hardware to run an ILIAS installation is always dependent from the number of users and the kind of usage. An ILIAS installation with 5,000 registered users that download some files from time to time needs less hardware than an installation with 30,000 users of whom several hundered are running online exams on the server.
The following example shall give an idea about the necessary hardware for an institution starting with ILIAS.
Number of Users and Kind of Usage
ILIAS is set up for about 4,000 registered users. Based on empirical values this number of registered users results in a number of around 40 concurrent users.
The installation will be used to distribute learning materials (files, learning modules, glossaries, ...), to run courses, assessments and surveys and for collaborative learning and team work.
Requirements
A recommended web server to fit to these needs would be a common dual core web server with 4 GByte RAM.
Bandwidth of the web server connection should be at least 100Mbit/sec.
Usually, 250 GByte are sufficient for the hard drive. 25 GByte would be used by the operating system and ILIAS itself. 225 GByte would remain for the client's data base and file system.
