Isn't facebook rolling fantastillion servers with muni-AC as main power source, to have minimum amount of conversions and on-site equipment to avoid extra equipment caused outages and powerlosses And DC as backup power, as UPS/flywheel/etc will be DC, and no point inverting it again and incur new losses and inverter which can fail (actually most common reason for power outages for us) I would say it's technically superior solution to have primary AC and backup DC PSU. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
