Roman (der8auer) takes us on a comprehensive walk-through of the OEDIV datacenter facilities in Bielefeld, Germany, focusing on both the underlying facility infrastructure and enterprise server hardware. He starts deep in the basement where fiber optic connections and 10,000V power feeds enter the building, detailing the dual-redundant power distribution networks. Around 8:20 he steps through the massive 480-battery UPS room—including a funny moment around 9:02 where he stumbles over a raised floor curb designed specifically to act as an acid retention basin if the batteries ever leak. The tour continues through the pre-heated 1,500 HP diesel backup generator, the oxygen-reduction fire prevention system operating at 17.1% O2, and the rooftop evaporative chillers before heading into the server aisles.
The hardware section gets particularly detailed around 29:25 when he gets up close with an IBM Power10 (Power E1080) system and dissects its modular components with an IBM technician. He shows off the custom OMI DDIMM memory cards, heavy-duty VRM modules, and dense point-to-point CPU interconnect cabling. Watching the server spin up its jet-engine fans after a SpongeBob transition card at 35:06 really conveys the scale and noise of this gear. The video closes out with a look at Cisco x86 blade enclosures, an IBM z15 mainframe, Dell EMC PowerMax all-flash storage arrays, and an automated robotic tape library.
It is a fascinating tour for anyone interested in high-availability enterprise infrastructure where redundancy is built into every single pipe, cable, and power line. The level of detail regarding environmental controls—like the membrane oxygen scrubbers and the dual-loop water cooling systems—makes this much more engaging than a typical rack-and-stack video. Seeing exotic, non-x86 architectures like IBM Power and Z-series in a live production environment is definitely the highlight.
