[ISG News] 2025 in review
by Christian Herzog 11 Dec '25

11 Dec '25

ISG News has posted a new item, '2025 in review' This post is meant to give you a short overview of what has been accomplished in D-PHYS IT by ISG this year. We’ve been hard at work to further improve and extend our services for you, our customers. Some highlights of 2025: Lab networks: in order to assist the research groups with their increasingly complex networking requirements, we introduced a new isolated networking scheme. Managed workstations: the migrations to Windows 11 and Debian Bookworm have been completed. Storage and backup: we modernized the backup infrastructure and implemented significant behind-the-scenes improvements. The disk space occupied by data and backup grew only slightly from 5.3 PiB to 5.4 PiB. Infrastructure work: our Debian and Ubuntu mirror has been migrated to new hardware. Windows software deployment: we're currently beta-testing the Baramundi service to replace our long-established Windows software deployment. Security (Linux): we had to develop tooling to detect and protect from DDOS/AI scraping. Our firewall now limits connections from 90+ cloud hosting providers on servers and is more restricted on workstations. Matrix/Element: usage almost doubled to 1461 active users. Knowledge management: together with 3 research groups we're currently evaluating an AI system to interactively explore the knowledge hidden in lab journals and publications. Outages: apart from some short-term network interruptions, our systems were very stable in 2025. Apprentice: our apprentice Vanessa successfully completed her training in August. Her successor Alessio will start in February. I would like to take this opportunity to thank my whole team for their hard and dedicated work all year long. Happy Holidays and see you in 2026!

[ISG News] groupdata downtime
by Stephan Mueller 01 Dec '25

01 Dec '25

ISG News has posted a new item, 'groupdata downtime' Upcoming downtime: XFSv5 on groupdata network shares There will be a larger maitainance downtime for all D-PHYS grouphares. Other shares like Web, IPA, ... are not affected. The downtime is scheduled for: Saturday, January 3rd 2026 20:00 -- Sunday, January 4th 2026 10:00 You will not be able to access any shares on groupdata during this time. Afterwards everything will just work as before. If this will disrupt any essential operation, let us know asap! There will be another reminder closer to the downtime. Technical background: We need to upgrade the XFS filesystem metadata. This cannot be done in place, so we have to backup, reformat and restore all shares. We need to sync roughly 180TB so it will just take some time.
