Node Power Consumption

Here is documentation on using the multimeter and conducting power consumption tests.

A brief estimate of the power consumption of Medusa's nodes:

• 10 Nodes Idle: 5.1 amps
• 10 Nodes in heavy use: 7.5 amps
• This test was done with nodes that have 2 IBM drives and 1 Samsung

More detailed information in the form of a graph of node power consumption from April 29 2004:

Below are older measurements of power consumption. Note that these graphs do not reflect the current hardware configuration of the nodes.
