This feature enables the user to configure how the system handles redundant power supply configurations. Balanced Mode shares the power delivery equally between all installed power supplies. All High Efficiency Mode options provide the most power efficient operation with redundant power supplies by keeping half of the power supplies in standby mode at lower power usage levels. The High Efficiency Mode options allow the user to choose which power supply is placed in standby. To achieve a semi-random distribution with a group of systems, Auto chooses between the odd or even power supply based on the server's serial number.
