Command sets and functions

摘要

Systems and methods are disclosed for command sets and functions for communication between and operation of devices, especially data storage devices. In an embodiment, an apparatus may comprise a data storage device configured to store data as objects, each object including a tracking indicator to identify the object, and a data field with a variable size to store user data. The data storage device may further be configured to receive a command including an operation directed to an object and an indicator that specifies a variation of the operation to be performed. In another embodiment, a memory device may store instructions that cause a processor to perform a method comprising storing data as objects to a nonvolatile media, and receiving a command including an operation directed to an object and an indicator that specifies a variation of the operation to be performed.

1. An apparatus comprising:
a data storage memory device configured to:
store data as objects, each object including:
a tracking indicator to identify the object;a data field with a variable size to store user data;at least one metadata field; andreceive a command including an operation directed to an object and an indicator that specifies a variation of the operation to be performed, the indicator includes an early exit flag directing the data storage device to employ less than all recovery methods available to the data storage device in implementing the operation when the operation fails to complete successfully; andreturn an operation status when the operation fails to complete after employing the less than all recovery methods in response to the command.
