2019 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 2019:
- Ansible deployment: while we had already started to deploy servers using ansible as early as 2015, it was in 2019 that we consolidated and migrated almost all server configuration to this system and now have a common base for the D-PHYS server infrastructure.
- Storage server separation: in the past years a constant growth in both volume and bandwidth of our SAN storage system caused occasional performance issues for some users. To alleviate this, we split our single SAN frontend file server into 4 individual machines (D-PHYS general, IPA, IGP and galaxy) in order to distribute the load.
- New web server: at the end of 2018 we purchased a new D-PHYS web server to replace the previous 10-year-old system. In 2019 we devised a completely new and upgraded web server setup on this new machine and migrated all D-PHYS hosted web shares to the new system. If you are the owner of one of our web shares, please make sure to read the updated documentation for things that have changed.
- Network migration: the extensive Hönggerberg network reorganization we reported last year is even more complex than we initially thought, so there's no end-user-tangible progress this year - which doesn't mean there hasn't been a lot of behind-the-scenes work.
- Storage: in 2019 the disk space occupied by data and backup grew from 2.1 PiB to 2.7 PiB, continuing the obvious trend of ever-growing data. The end of 2019 also saw a substantial expansion of the available disk capacity.
- Clusters: we inherited two HPC clusters from CSCS that we're now running locally.
- InfluxDB / Grafana: we included this popular time-series database / visualization combination into our service catalog.
- Outages: apart from a pre-announced migration window and some short-term network interruptions, our systems have been very stable in 2019.
- OS upgrades: The Windows team was active in getting rid of the remaining Windows 7 machines and upgrading Windows 10 to the 1809 build, while on the Linux side workstations were upgraded to Ubuntu 18.04 and a first batch of servers to Debian buster.
- Software upgrades: the FileMaker server has been upgraded.
- UCC: the UCC project of Informatikdienste was stopped due to nonfulfillment of the technical requirements and all deployed services and devices have been rolled back. The whole project will be reevaluated from scratch.
- 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 2020!
