Methods, systems and devices relating to data storage interfaces for managing data address spaces in data storage devices

摘要

Data address management systems, methods, devices and uses for minimizing interaction with data consumers' data on data storage devices, an embodiment comprising an external bus for communicatively interfacing the data storage system and data consumers; at least one storage medium components, each storage medium component comprising a plurality of storage locations having a unique storage location indicators; a translation layer module comprising a data address space having data addresses associable with storage location indicators; and a controller configured to store data in the storage locations and creating associations in the translation layer module between data addresses and the physical location indicators; wherein the data address space is accessible by the data consumer for addressing requests relating to data stored on the storage device and wherein the controller is configured to manipulate the arrangement of the data addresses in the data address space.

1. A data storage system for storing data from a data consumer, the data storage system comprising:
an external communication interface with the data consumer; a storage medium component comprising a plurality of storage locations, each of the storage locations having a unique storage location indicator associated therewith; a translation layer module defining a data address space having a plurality of data addresses, each of the data addresses being associable with at least one said unique storage location indicator; and a controller configured to carry out computer readable instructions for writing and reading data in the storage locations and amending associations in the translation layer module between data addresses and the storage location indicators; wherein the data address space is accessible by the data consumer via the external communication interface for addressing data requests to the storage medium component and wherein the controller is configured to manipulate arrangement of the data addresses in the data address space by changing the associations between the data addresses and the storage location indicators; wherein the controller manipulates the data addresses by making a copy of given data associated with a first data address, writing the copy to a second storage location, and associating a second data address in the translation layer module with a given storage location indicator related to the second storage location; and wherein the system is further configured to communicate a notification to the data consumer that the second data address is associated with the given data upon at least one of the writing of the copy to the second storage location, a notification threshold being reached wherein a plurality of notifications are generated by the controller, and receipt of a subsequent request by the data consumer for the given data.
