2017 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 2017:
- Account expiry: in early 2017 we finished assessing all ~7600 D-PHYS accounts and blocked the expired ones. We also tied all D-PHYS accounts to their nethz counterparts wherever possible. This allows us to make use of ETH’s employment information from now on. While we were at it:
- New LDAP servers: Since implementing account expiration meant touching most aspects of our identity management infrastructure anyway, we decided to completely overhaul our LDAP user database. We reworked the LDAP schema (the original one dating back to the early 90s) and set up a 3-way replicating OpenLDAP cluster.
- Windows Server Cluster: Several mission critical Windows Server instances have been moved to a newly created Windows Cluster. This complements last year’s Linux cluster.
- Storage: in 2017 the disk space occupied by data and backup grew from 1.3 PiB to 1.6 PiB, making this a very slow year as far as storage growth is concerned.
- Server room migration: in August we had to move most of D-PHYS’s servers three rack rows down in the HIT D 13 server room. We now have a solid foundation for our servers for the next years.
- Outages: apart from the above-mentioned migration, some short-term network interruptions and the unfortunate file server issues of late our systems have been very stable in 2017.
- Web server upgrade: in January we upgraded the operating system on the D-PHYS web server. We also used the occasion to clean up a lot of legacy cruft.
- OS upgrades: 2017 brought new OS versions for almost every system: the Windows 10 rollout picked up steam, High Sierra arrived on the Macs and Ubuntu 16.04 on the remaining Linux workstations.
- eXile: we migrated the configuration management from Puppet to Ansible and then re-installed all eXile gateways in a fully automated way with the latest Debian release.
- UCC: we laid the technical groundwork and performed implementation tests for the upcoming UCC rollout which will replace the existing ETH telephony system with an all-IP based solution.
- IT security: we participate in and support the ETH-wide IT security initiative.
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 2018!
