I signed up for the programme hoping to get a better grip on modern cooling tech, and it delivered. The hands‑on labs on free‑cooling and hybrid UPS systems were spot‑on, and I actually used the sizing worksheets to redesign our rack layout back at work. The PDFs were clear and the video snippets kept things lively. I left feeling confident that I can drive a 10‑percent reduction in power costs at our London data centre. A solid course—just wish there were a few more live Q&A sessions.
