Abstract: In some aspects, devices, systems, and methods are provided that relate to data deduplication performed in data storage devices, such as solid-state drives (SSD) or drives of any other type. In some aspects, devices, systems, and methods are provided that relate to hierarchical data deduplication at a local and system level, such as in a storage system built with one or more SSDs having built-in data deduplication functionality.

In hierarchical data deduplication, no IDs (or signatures) are required to be stored at a system level. In some aspects, data steering is provided that enables data storing coordination in a system that consists of a set of data storage device (e.g., SSDs) having built-in data deduplication.

Abstract: Described is a system that allows for the efficient management of reallocating data between tiers of an automated storage tiering system. In certain configurations, protected data that is stored within the storage system may include a user data portion and a redundant data portion. Accordingly, to conserve space on higher storage tiers, the system may separate user data from the redundant data when reallocating data between tiers. For example, the system may only allocate the user data portion to higher storage tiers thereby conserving the space that would otherwise be taken by the redundant data, which remains, or is demoted to a lower tier. Moreover, the reallocation may occur during scheduled reallocation cycles, and accordingly, the reallocation of the separated protected data may occur without any additional tiering overhead.

The method includes writing an indirection journal to each host blockset which are associated with the assigned major sequence number. The method includes writing data, in a garbage collection (GC) stream, to other blocksets of the flash storage system. The GC blocksets are assigned a major sequence number, based on the most recently closed host blockset, and a minor sequence number, incremented from the most recently closed GC blockset. The method includes writing an indirection journal to each GC blockset which are associated with the assigned major and minor sequence numbers. The indirection table is constructed by replaying the journals of the blocksets in order of major sequence and minor sequence numbers.

In response to the command, the source memory device may read data out to the bus, and the target memory may read the data from the bus and store the data starting at the target address without further commands from the controller.

Abstract: The present disclosure describes technologies and techniques for use with a data storage controller (such as a non-volatile memory (NVM) controller) to implement self-trimming of media data. In illustrative examples, an NVM controller stores a stream of video data in a NAND storage device, such as video obtained by a security camera. The controller also stores time stamps corresponding to portions of the video data. The controller then periodically (or during idle times) scans the stored information to identify video data that has exceeded a maximum data lifetime, such as data older than one week. Such data is deemed to be old/expired and is trimmed by the controller (by, e.g., marking corresponding entries in an allocation table as deleted or invalid). In this manner, the controller performs self-trimming of older video data to, for example, limit write amplification. NVMe examples are provided.

The controller previously manages a correspondence relationship between physical addresses indicating the memory regions and stream identifiers, before first write data is received by the controller. The controller controls the nonvolatile memories such that the first write data is stored in a first memory region of a physical address which is managed corresponding to a first stream identifier of the first write data in the correspondence relationship. The first write data is transferred to the nonvolatile memories based on the correspondence relationship, regardless of whether second write data having a second stream identifier is received by the controller.

Abstract: Technology is disclosed herein for aborting a tail portion of a command queue in a storage device. In one aspect, one or more control circuits of a storage system are configured to abort tasks at a tail end of a command queue in response to receiving a task tail abort command. However, tasks at the head end of the command queue may still be executed. Thus, the head end of the command queue need not be rebuilt after the task tail abort command is performed. Therefore, considerable time is saved by not having to rebuild the head end of the command queue. Note that the task tail abort command may be received while the storage system is in a sequential command execution mode, in which tasks are executed in the order of their respective task identifiers.
