About this tool

Accurate rack planning prevents the two most common data-centre surprises: running out of U space mid-deployment and tripping a PDU breaker because load exceeded circuit capacity. Weight is equally important: standard 2-post open frame racks typically support 500–700 kg, while heavy-duty 4-post closed cabinets may support 1,000–1,500 kg; always verify with your vendor. Power figures here are nameplate maximums; actual draw is usually 50–70% of rated, so consider using measured values from a power analyser once equipment is live.
