Redundant PSU & Proliant Servers

Hi All,

Just trying to do some calculations for UPS.

When a server has a redundant PSU, how much more current does the server drain. Say the server had a 575W PSU in it, and we add another 575W Redundant PSU, does this mean the server will now drain 575W x 2 = 1150W?

Thx

I would think it would be something like this

575w std 1 psu

maybe 650w with std & redundant psu

Hi David

When redundant power supply is installed , it will share the load with existing power supply so power consumption remains the same

If it's a G1 or newer server you can stop guessing about sizing for a UPS and use the power calculators at http://h30099.www3.hp.com/configurator/calc/Power%20Calculator%20Catalog.xls
