The Dell racks contain 30 compute nodes, two UPS units, two disks arrays and two switches. We have measured 19 nodes power consumption (pulling one of the dual power units out) with a Kill-A-Watt meter for over 775+ total hours. The mean power consumption rate is 418.4 watts. That totals to 109,956 KwH/year in power consumption ((watts/ | The Dell racks contain 30 compute nodes, two UPS units, two disks arrays and two switches.
