2023 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. Unfortunately, two of our colleagues had to take extended sick leaves this year, so we didn't have as much capacity for innovation and had to focus on system maintenance.

Some highlights of 2023:

  • Storage: in the first half of 2023, we performed a major overhaul on our storage and backup infrastructure in both hardware and software. The disk space occupied by data and backup grew from 4.8 PiB to 5.1 PiB.
  • Infrastructure work: our Ansible deployment setup was further extended and refined. All Windows servers have been added as well as the macOS clients.
    All eGroupware users were migrated to the new SOGo calendar. We also enabled DKIM signing on our D-PHYS mailserver. The Windows HyperV cluster has been upgraded for better performance.
  • Matrix/Element: We upgraded both the OS and the Matrix server software. This year we counted 748 active users on 2579 devices (1019 Windows, 517 Linux, 424 Mac, 619 Mobile), who sent 1'086'537 messages in 5'510 rooms created on our server. Our users also participated in 763 other rooms with 1'157'466 messages.
  • ISG lecture series: our Basics of Computing Environments for Scientists lecture series was held twice in 2023 with shockingly low attendance.
  • Outages: apart from some short-term network interruptions, our systems were pretty stable in 2023.
  • OS upgrades: work is well underway to migrate the managed Linux workstations from Ubuntu to Debian and the majority of servers are now running Debian bookworm. The Windows team started the Windows 11 rollout. Most of the managed Macs were upgraded to macOS Ventura.
  • Software upgrades: mostly incremental upgrades in our Windows and Linux software list this year.
  • IT security: with the world being what it is, IT security plays an ever increasing role in our work and permeates all our plans and projects. We also take part in the current rewrite of ETH's IT security regulations. On the Windows virus scanner front, Sophos was EOL'd and replaced by Windows Defender.

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 2024!
