摘要:
The disclosure is related to systems and methods of distributing data in devices with multiple storage entities. In a particular embodiment, a system is disclosed that includes multiple storage entities, with each storage entity having a sub-controller. A controller is communicatively coupled to each of the multiple storage entities. The controller is configured to send at least one of a respective copy of data or metadata associated with the respective copy of the data to each of the multiple storage entities. Upon receipt of the at least one of the respective copy of the data or the metadata associated with the respective copy of the data, each sub-controller provides storage competency information of the respective storage entity for the respective copy of the data. Upon receiving storage competency information for the multiple storage entities, the controller selects a particular one of the multiple storage entities and notifies the selected storage entity to store the respective copy of the data.
