Redundant power supply configuration for a data center

A method for power supply operation, comprising:nreceiving an instruction to operate a plurality of power supplies at a high current mode, each of the power supplies comprises an individual feedback controller;wherein the power supplies are redundant and serve as backups to one another to ensure that there is not a single point of failure as a redundant power supply configuration;wherein the power supplies are connected to a storage device having planar disks for reading and writing data;calculating an individual current for each of the plurality of power supplies to total a high current at the high current mode;operating the plurality of power supplies at the high current mode to provide the high current at the high current mode to the storage device having the planar disks for reading and writing data;in response to operation at the high current mode being complete, operating the plurality of power supplies at a normal mode to provide a normal current at the normal mode;wherein operating the plurality of power supplies to supply the high current of the high current mode while causing the plurality of power supplies to operate at a higher efficiency than the normal mode and operate at a lower temperature than the normal mode, each of the plurality of power supplies that operate at the lower temperature while supplying the high current;the plurality of power supplies increasing output to a load to operate at the lower temperature while supplying the high current of the high current mode;wherein operating the plurality of power supplies to supply the high current at the high current mode occurs when booting up the planar disks of the storage device, which results in stopping the plurality of power supplies from operating in the redundant power supply configuration to the storage device such that the power supplies are no longer redundant and do not serve as backups to one another;wherein operating the plurality of power supplies to supply the high current at the high current mode occurs when starting the planar disks of the storage device from rest, which results in stopping the plurality of power supplies from operating in the redundant power supply configuration to the storage device such that the power supplies are no longer redundant and do not serve as backups to one another;wherein operating the plurality of power supplies to supply the high current at the high current mode occurs when demand for the storage device is high, which results in stopping the plurality of power supplies from operating in the redundant power supply configuration to the storage device such that the power supplies are no longer redundant and do not serve as backups to one another; andwherein operating the plurality of power supplies at the normal mode to provide the normal current causes the plurality of power supplies to again start operating in the redundant power supply configuration.

A power system, comprising:npower supplies configured to provide redundant power, each of the power supplies comprises an individual feedback controller;wherein the power supplies are redundant and serve as backups to one another to ensure that there is not a single point of failure as a redundant power supply configuration;wherein the power supplies are connected to a storage device having planar disks for reading and writing data; anda power manager configured to control the power supplies, wherein the power manager is configured to:receive an instruction to operate the power supplies at a high current mode;calculate an individual current for each of the power supplies in which a total of the individual current amounts to a high current at the high current mode;operate the power supplies at the high current mode to provide the high current to the storage device having the planar disks for reading and writing data; andin response to operation at the high current mode being complete, operate the power supplies at a normal mode to provide a normal current at the normal mode;wherein operating the power supplies to supply the high current of the high current mode while causing the power supplies to operate at a higher efficiency than the normal mode and operate at a lower temperature than the normal mode, each of the power supplies that operate at the lower temperate while supplying the high current;the power supplies increasing output to the storage device having the planar disks to operate at the lower temperature while supplying the high current of the high current mode;wherein operating the plurality of power supplies to supply the high current at the high current mode occurs when booting up the planar disks of the storage device, which results in stopping the plurality of power supplies from operating in the redundant power supply configuration to the storage device such that the power supplies are no longer redundant and do not serve as backups to one another;wherein operating the plurality of power supplies to supply the high current at the high current mode occurs when starting the planar disks of the storage device from rest, which results in stopping the plurality of power supplies from operating in the redundant power supply configuration to the storage device such that the power supplies are no longer redundant and do not serve as backups to one another;wherein operating the plurality of power supplies to supply the high current at the high current mode occurs when demand for the storage device is high, which results in stopping the plurality of power supplies from operating in the redundant power supply configuration to the storage device such that the power supplies are no longer redundant and do not serve as backups to one another; andwherein operating the plurality of power supplies at the normal mode to provide the normal current causes the plurality of power supplies to again start operating in the redundant power supply configuration.
