Starting a new WWW service This document gives a short description which decisions have to be made before a new WWWW service within the Science Faculty can be started. Contact Communications C&CZ is not the communications department, officially all communication and therefore websites should be provided and endorsed by the communication department. However, sometimes a website is actually an application with a web interface and this can usually not be provided via the official communication website....
Servers and Workstations C&CZ manages about 400 Linux servers and hundreds of Linux workstations and a few servers with MS-Windows, primarily in the domain science.ru.nl. Dual boot Windows/Linux machines are counted twice. The servers are distributed over three datacenters. Workstations C&CZ manages (for departments) workstations with Ubuntu Linux. There are also workstations in the PC-rooms for general use by anybody with a Science login, but also by all RU employees and students and guests with a temporary login....
Science login A Science login provides faculty students and employees access to services like networked storage, computer labs, JupyterHub, clusternodes and GitLab & Mattermost. A Science login usually resembles your name and does not contain periods, capital letters or an at sign (@). For example johndoe. All settings related to your Science login, like setting your password, MFA, storage, groups and email aliases can be managed in DIY. See the DIY howto for more information....

At the faculty of science, C&CZ manages a number of compute clusters and we have our own computer room with a few dozen racks for server hardware and also some racks in the Forum computer room. Financial model The faculty in general doesn’t own (m)any compute nodes, departments purchase their own servers (we can help configure these), which we install and manage during their lifetime. All clusternodes can be integrated in our SLURM cluster management....
A new storage option has been developed by C&CZ. This page will show the technical details and properties of this storage, which will hopefully help you make a decision if this is something you want. Any storage we handout we call a “volume”. For these ZFS volumes: Size Storage size can be as large as you want, but smaller than the amount we can put in a single machine. Currently (2024+) we can buy machines with roughly 140-200 TB storage....
You might have received an email that your personal or group network disk is almost full. This articles describes some tools to identify large files/directories and cleanup disk space.
