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 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.
