Method and apparatus for performing power analytics of a storage system

Abstract

A storage system comprises one or more storage devices, power supplies supplying power to the storage device, a processor that performs in response to determining that the total power consumption of the one or more storage devices is less than a first percentage threshold of a load of the active power supplies, deactivating one or more of the active power supplies until the total power consumption is equal to or greater than the first percentage threshold of a load of each of the active power supplies, and in response to determining that the total power consumption is equal to or greater than a second percentage threshold of a load of each of the active power supplies, activating one or more of the deactivated ones of the power supplies until the total power consumption is less than the second percentage threshold of the load of each of the active power supplies.

What is claimed is: 
     
         1 . A storage system comprising:
 one or more storage devices;   a plurality of power supplies configured to supply power to the storage device;   a processor; and   a memory having stored thereon instructions that, when executed by the processor, cause the processor to perform:
 determining whether multiple power supplies of the plurality of power supplies are active; 
 in response to determining that multiple power supplies are active: 
 determining a total power consumption of the one or more storage devices; 
 in response to determining that the total power consumption is less than a first percentage threshold of a load of active ones of the power supplies,
 deactivating one or more of the active ones of the power supplies until the total power consumption is equal to or greater than the first percentage threshold of a load of each of the active ones of the power supplies; and 
 
 in response to determining that the total power consumption is equal to or greater than a second percentage threshold of a load of each of the active ones of the power supplies,
 activating one or more of the deactivated ones of the power supplies until the total power consumption is less than the second percentage threshold of the load of each of the active ones of the power supplies.
