System and method for power management of a storage enclosure

A storage enclosure, comprising:

• at least one storage resource configured to communicate with a host via a particular transmission protocol;
• a management module configured to:
• receive a power down command via the particular transmission protocol from the host;
• in response to the receipt of the power down command, set a variable indicating that the at least one storage resource is to be placed in a low-power state
• receive a power up command via the particular transmission protocol from the host;
• and
• in response to the receipt of the power down command, set a variable indicating that the at least one storage resource is to be transitioned in a high-power state;
• and a power supply module comprising:
• at least one power supply configured to supply electrical energy to the at least one storage resource when the variable indicating that the at least one storage resource is to placed in the high-power state;
• and
• an auxiliary power supply configured to supply electrical energy to the management module when the variable indicating that the at least one storage resource is to placed in the low-power state.

A method for power management of a storage enclosure, comprising:

• receiving a command to power down a storage enclosure from a host communicatively coupled to the storage enclosure, the command communicated via a particular transmission protocol used to communicate input/output data between the host and the storage enclosure;
• in response to the communication of the command to power down the storage enclosure, setting a variable indicating that the storage enclosure is to be placed in a low-power state;
• receiving a command to power up the storage enclosure from the host, the command communicated via the particular transmission protocol;
• in response to the communication of the command to power up the storage enclosure, setting a variable indicating that the storage enclosure is to be placed in a high-power state;
• maintaining at least one power supply to supply electrical energy to one or more storage resources of the storage enclosure when the variable indicating that the at least one storage resource is to placed in the high-power state;
• and
• maintaining an auxiliary power supply to supply electrical energy to the one or more storage resources of the storage enclosure when the variable indicating that the at least one storage resource is to placed in the low-power state.
