US 2016/0239076 A1 · POWER SWITCHING TECHNIQUE FOR ARCHIVAL DATA STORAGE ENCLOSURE

Abstract

A method of power management of a multiple-data-storage-devices enclosure is disclosed. In some embodiments, the method includes: receiving a network connection and power from a data connection port detachably coupled to a network cable; identifying a subset of data storage devices within the enclosure to activate; powering off components within the enclosure other than the subset of the data storage devices; for each data storage device in the subset that is not yet powered, activating the data storage device by: monitoring power consumption drawn from the data connection port; identifying a sequence of components associated with the data storage device, wherein the components within the sequence, when powered, together provide access to the data storage device; and powering on each component in the sequence when a previous component in the sequence has reached a steady state power consumption level.

Dependent claims

A method comprising:

in response to receiving a request to access data in an enclosure powered by a data connection port,
identifying a first storage device within the enclosure to activate based, at least in part, on the request;
identifying a component associated with the first storage device, wherein the component facilitates access to the first storage device;
and
supplying power received via the data connection port to activate the first storage device;
monitoring power consumption at the data connection port;
and
in response to the power consumption reaching a steady state, supplying power received via the data connection port to activate the component.

5 more elements

A non-transitory machine readable medium having stored thereon instructions for activating components and storage devices in an enclosure powered by a data connection port comprising machine executable code which when executed by at least one machine, causes the machine to:

in response to receipt of a request to access data in the enclosure,
identify a first storage device within the enclosure to activate based, at least in part, on the request;
identify a component associated with the first storage device, wherein the component facilitates access to the first storage device;
and
supply power received via the data connection port to activate the first storage device;
monitor power consumption at the data connection port;
and
in response to the power consumption reaching a steady state, supply power received via the data connection port to activate the component.

5 more elements

An enclosure comprising:

a data connection port configured to supply power to the enclosure;
a first storage device;
a component which facilitates access to the first storage device;
a memory containing machine readable medium comprising machine executable code having stored thereon instructions for activating components and storage devices in the enclosure;
and
a processor coupled to the memory, the processor configured to execute the machine executable code to cause the enclosure to:
in response to receipt of a request to access data in the enclosure,
activate the first storage device based, at least in part, on the request, wherein the machine executable code executable by the processor to cause the enclosure to activate the first storage device comprises machine executable code executable by the processor to cause the enclosure to supply power received via the data connection port to the first storage device;
monitor power consumption at the data connection port;
and
in response to the power consumption reaching a steady state, supply power received via the data connection port to activate the component.
