Water Cooled Racks? What Could Possibly Go Wrong?
A few jobs ago I worked for a UK company that had a site in Sweden, on the campus of a university. Being Swedes, they were keen on environmental stuff and the campus had a fancy, experimental, heating & ventilation infrastructure. The system was comprised of water filled pipes running everywhere to move heat from where it wasn't needed, to where it was. This included the server room in our leased building. The uni's facilities people connected all their plumbing and heat exchangers into special server racks they'd had designed for water cooling. Everything worked well for about 18 months or so, until the day there was a leak elsewhere on campus. We lost several Proliants and a storage array. The liability arguments were still raging when I left the company.
