In one embodiment, a data storage device is provided comprising a volatile memory, a non-volatile memory, and a controller. The controller is configured to: receive data and a logical address from a host, wherein the data is tagged with an identifier of an application on the host; store the data at a physical address in the non-volatile memory; maintain a logical-to-physical address table that comprises an entry associating the logical address, physical address, and identifier; determine that the application is subsequently reloaded on the host; and cache, in the volatile memory, a portion of the logical-to-physical address table that comprises the entry for the identifier.

Abstract: Aspects of a storage device including a memory and a controller are provided which optimize read look ahead (RLA) performance based on zone configurations or stored metadata. The controller stores in memory information previously received from a host, including a zone configuration or other information from which metadata associated with subsequent data to be pre-fetched in RLA may be determined. When the stored information includes the zone configuration, the controller reads data from memory in response to a host command and limits pre-fetching of subsequent data from the memory based on the zone configuration. When the stored information includes metadata, the controller reads the metadata associated with subsequent data from the memory, and limits pre-fetching of the subsequent data based on the metadata. Thus, resources of the storage device that are typically used for RLA may instead be used for other operations, improving the efficiency of the storage device.

Abstract: Systems, methods, and data storage devices for data recovery from network storage systems are described.

Responsive to a read error when reading a data unit, the data storage device establishes a secure data transfer connection with the network storage system to request the failed data unit from the network storage system. The data unit retrieved from the network storage system may be used to respond to the original read request and restore the data unit in the data storage device.

Abstract: Storage devices store not only host data, but also control data related to operations of the storage device associated with the data. Control data is stored within blocks of memory called control blocks. As storage devices are configured to communicate with numerous hosts and namespaces, proper management of the available control blocks can avoid numerous problems such as mixed control block usage that punish certain hosts based on actions of other, non-related hosts. Methods and devices that efficiently manage control blocks include a control block management logic configured to process a request to generate a new namespace and parse the namespace request to determine the number of control blocks required. These separate control blocks for the requested namespace can be partitioned. Finally, control block activity for the requested namespace is directed only to the partitioned control blocks. Thus, the various control block activity between hosts is separate and not mixed.

Other embodiments are provided.

The controller can receive a data stream from a host device, the data stream indicating a plurality of encryption keys associated with the data stream, and segregate the data stream into a plurality of data stream portions based on the plurality of encryption keys. The controller can encode the plurality of data stream portions into a plurality of encoded data stream portions with the plurality of encryption keys. The controller also can generate a mapping indicating an association between each of the plurality of encryption keys with a respective one of the plurality of encoded data stream portions. Thus, the controller may store the plurality of encoded data stream portions and the plurality of encryption keys in the memory based on the mapping, thereby improving security access to data stored in the storage device.

Abstract: Aspects of a storage device including a memory and a controller are provided. The memory includes a plurality of non-volatile memory packages coupled to the switch, with each non-volatile memory package including a plurality of non-volatile memory dies. The controller monitors a wear level of each non-volatile memory package in the plurality of non-volatile memory packages connected to the controller via the switch. The controller determines whether a wear level of a first non-volatile memory package of the plurality of non-volatile memory packages exceeds a wear level threshold. The controller also can transfer data from the first non-volatile memory package to a second non-volatile memory package of the plurality of non-volatile memory packages through the switch based on the wear level of the first non-volatile memory package exceeding the wear level threshold. Thus, the controller may facilitate a persistent switch-based storage controller, thereby improving memory capacity of the storage device.
