Abstract
A storage device includes storage media and a controller to control access of the storage media. The controller receives an erase command used to specify an erase operation of at least one portion of the storage media. The erase command has a control field controllable by a requestor device that submitted the erase command to the storage device, where the control field has one or more portions settable to cause the storage device to perform one or more of: reporting a progress of the erase operation, and modifying an operational state of the erase operation.
Claims18
A storage device comprising:
- storage media;
- a controller to control access of the storage media, the controller to receive an erase command used to specify an erase operation of at least one portion of the storage media,
- wherein the erase command has a control field controllable by a requestor device that submitted the erase command to the storage device, the control field having one or more portions settable to cause the storage device to perform one or more of:
- reporting a progress of the erase operation, and modifying an operational state of the erase operation.
An article comprising at least one computer-readable storage medium containing instructions that upon execution cause a processor to:
- receive a request to perform a secure erase operation, wherein the request specifies at least one feature associated with the secure erase operation to activate, the at least one feature including one or more of:
- progress reporting of the secure erase operation;
- and modifying an operational state of the secure erase operation;
- in response to receiving the request, generate a secure erase command having a control field populated with a value according to the at least one feature that has been activated;
- and
- send the secure erase command to a storage device to command the storage device to activate the at least one feature associated with the secure erase operation.
A method of controlling an erase operation of a storage device comprising:
- receiving, by the storage device from a requestor device, an erase command having a control field populated by the requestor device to command performance of one or more of reporting a progress of an erase operation of storage media in the storage device;
- and modifying an operational state of the erase operation;
- in response to the erase command, performing, at the storage device, one or more of reporting a progress of an erase operation of storage media in the storage device;
- and modifying the erase operation.
