In equipment which has dual power supplies - e.g. a server - how is power draw balanced between them?
Will they be "active/active", with load evenly spread between both PSUs? Or will they be "active/passive", with one PSU supplying most (all?) power required by the server, and the other drawing no power (or close to no power) but standing by ready to take over if required? Or something else?
We have a server with dual power supplies. Each power supply is on and connected to mains power. The server currently requires 400 watts of power.
Will 400W be supplied by PSU #1 (and the mains connection it uses), and 0W supplied by PSU #2?
Will 200W be supplied by PSU #1, and 200W supplied by PSU #2?
