We are getting ready to deploy our first set of clusters and in the preinstall brief we hit a little snag regarding power. The specs state that with dual power supplies you need 208 volts per power supply. I have read in other post that the 3000 series should be OK with 120V if you only have 3 nodes. Can anyone confirm this? My goal is to have redundance if power was lost to a single power supply.
If we get the 4th node we will go with 208V, but currently I just don't have that kind of power or mainly a 208/240 UPS.
