Benjamin Redling

Professionally working in IT since 1999, I joined Prof. Hahn’s group in November 2006 as a system administrator.

Over the years I maintained a small FC-SAN, met Solaris with SAM-FS, planned and administred two compute clusters which I heavily upgraded all by myself, introduced the SLURM batch scheduler and a ganeti cluster for virtualization.

Currently I have to cope with the rough edges of frameworks depending on CUDA installations, the quirks of untrusted containers and the pros and cons of systemd.

Recent Working Experience

• Installation and maintenance of the groups SLURM cluster
• Setup and tuning of PostgreSQL installations
• Basic Linux infrastructure (NFS4 file server, OpenLDAP, Btrfs, ZFS)
• Web infrastructure (web- and application servers, reverse proxying, certificates)
• Monitoring with Check_MK
• Setup of ElasticSearch clusters
• Maintenance of the groups Ganeti (KVM/DRBD) cluster
• Configuration management and orchestration via Ansible and basic shell scripting
• Basic Python knowledge
