An application programming interface (API) that enables installation of an application as one or more key-value objects on a data storage drive such as a hard disk drive, a solid state drive or a hybrid drive. The API also enables execution of the application within a controlled environment of the data storage drive.

Active drive API

Methods, systems, and apparatuses are described for provisioning storage devices. An example method includes specifying a logical zone granularity for logical space associated with a disk drive. The method further includes provisioning a zone of a physical space of the disk drive based at least in part on the specified logical zone granularity. The method also includes storing compressed data in the zone in accordance with the provisioning.

Thinly provisioned disk drives with zone provisioning and compression in relation to zone granularity

A storage device controller includes a scheduler that implements selection logic for selecting commands for execution from a command queue according to a probability based on an in-queue age of each pending command.

Command scheduling for target latency distribution

A storage system such as a hard disc drive (HDD), solid-state drive (SSD), hybrid drive (SSHD), storage rack, set of storage racks, JBOD, array of discs, etc. may include a variety of storage media. Failures may be detected in the storage media of the storage system. Such a failure may affect the physical capacity of the storage system. A storage controller of the storage system initiates a media conversion that converts a portion of the storage media from media storing data according to a first recording scheme to a media storing data according to a second recording scheme. The second recording scheme stores data at a higher density compared to the first recording scheme.

Self-healing in a storage system

A data storage device includes a data store optimized organized into allocation units sized according to an sequential writing unit or garbage collection unit of the data store. Information is written to the allocation units as either coarse or fine-grained packets, which are packets of data that are self-describing and written together. Random writes received from a host to data already written into allocation units is written to another allocation unit, and a coarse-grained forward map is updated to reflect the physical location of the valid data that superseded data in the allocation unit until the allocation unit can be rewritten. Promotion operations are disclosed to compact data and garbage collect data by rewriting allocation units.

Dual granularity dynamic mapping with packetized storage

A method for managing data bands within an interlaced magnetic recording (IMR) architecture includes transmitting read/write characteristics of a logical block address space, the read/write characteristics including coupling information characterizing a physical arrangement of data blocks associated with different logical zones in the logical block address space, where each of the logical zones spans a continuous range of logical block addresses mapped to a series of data blocks physically interlaced with another series of data blocks corresponding to another one of the logical zones. The method further provides for executing a write command instructing a data write to a target logical zone of the logical zones, the write command being generated based on the transmitted coupling information.

Write management of physically coupled storage areas

An example method includes providing at least two data storage areas in a memory, providing a first amount of over-provisioning for a first of the at least two data storage areas and a second amount of over-provisioning for a second of the at least two data storage areas, categorizing data based on a characteristic of the data, and storing the data in one of the at least two data storage areas based on the categorization.

Data segregation in a storage device

Systems and methods are disclosed for object-based commands with quality of service identifiers. In an embodiment, an apparatus may comprise a memory device having a processor configured to store data as objects, each object including an object identifier field to track the object, and a user data field for user data of the object. The processor may be further configured to receive a command including an operation directed to an object, and a quality of service identifier that specifies a level of service associated with the operation. Commands may be directed toward put, get, and delete operations, among others.

Object-based commands with quality of service identifiers

Implementations disclosed herein provide a method comprising determining a workload on a disk cache with a storage device controller, determining a state of a free pool of the disk cache, receiving a data write request to the disk cache, segregating the free pool of the disk cache into a plurality of allocation units, allocating the plurality of allocation units out of order, as compared to a physical arrangement order of the allocation units in the disk cache, based on the workload, and storing data in the plurality of allocation units.

Disk cache allocation

A data storage device includes one or more storage media that include multiple physical storage locations. The device also includes at least one cache memory having a logical space that includes a plurality of separately managed logical block address (LBA) ranges. Additionally, a controller is included in the device. The controller is configured to receive data extents addressed by a first LBA and a logical block count. The controller is also configured to identify at least one separately managed LBA range of the plurality of separately managed LBA ranges in the at least one cache memory based on LBAs associated with at least some of the received data extents. The controller stores the at least some of the received data extents in substantially monotonically increasing LBA order in at least one physical storage location, of the at least one cache memory, assigned to the identified at least one LBA range.

Multi-tiered caching for data storage management in a device

Systems and methods are disclosed for object-based commands with data integrity identifiers. In an embodiment, an apparatus may comprise a data storage device configured to store data as objects, each object including a data field with a variable size to store user data, and to receive a command including an operation directed to an object and a data integrity identifier to perform the operation based on a hash value of the user data. Commands may be directed towards put, get, or delete operations, among others.
