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

Computing nodes are coupled via a network to communicate as a tree structure that performs a distributed computation. The nodes include a root node, intermediate nodes, and leaf nodes. At least some of the nodes obtain redundant results that are communicated together with a final result to the root node. The root node compares the redundant results to the final result to verify the final result.

Verifying distributed computing results via nodes configured according to a tree structure

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.

Object-based commands with data integrity identifiers

Apparatuses, systems, and methods for implementing a virtual machine on a data storage device are disclosed. In one embodiment, a device may comprise a communication interface responsive to a host, a processor, and a housing including the communication interface and the processor such that the device is removable from the host. The processor may be configured to receive a command from the host via the communication interface, process the command using a platform-independent program interface that is not dependent on the architecture of the device, and return results of the command to the host via the communication interface. In another embodiment, a method may comprise receiving at a data storage device a command from a host device, processing the command at the data storage device using a platform-independent program interface, and returning the results of the command from the data storage device to the host.

Data storage device having a virtual machine

A variety of data storage devices, methods and systems are implemented for control of memory associated with backup functionality. One such data storage device includes a power circuit that provides main power. The data storage device has a first solid-state memory circuit that maintains data in the absence of electrical power. A second memory circuit is subject to data loss in the absence of electrical power. A storage circuit stores energy and provides the stored energy to the second memory circuit in response to a loss of main power. A test circuit discharges a portion of the stored energy to provide output data indicative of power-providing capabilities of the storage circuit. A memory controller controls data transfers to the data storage device by temporarily storing data destined for the first solid-state memory circuit and setting the amount of memory available for temporary storage in response to the output data.

Systems, methods and devices for control of the operation of data storage devices using solid-state memory

Systems and methods are disclosed for object-based commands and functions. In an embodiment, an apparatus may comprise a data storage device configured to store data as variable-size objects, each object including a tracking indicator to identify the object, and to receive a command including an operation directed to an object and an indicator that specifies a variation of the operation to be performed. Tracking indicators may be selected by a host, and may have specific organization meaning to the host. A tenant accessing the data storage device may be restricted to accessing objects within one or more specific ranges of tracking indicators.

Object-based commands and functions

Systems and methods are disclosed for object-based commands with access control identifiers. In an embodiment, an apparatus may comprise a data storage device configured to store data as objects, each object including a tracking indicator to identify the object and a data field with a variable size to store user data. The data storage device may be further configured to receive a command including an operation directed to an object and an access control identifier used to determine whether to perform the operation. Commands may be directed towards put, get, or delete operations, among others.

Methods and apparatus for managing data storage in hybrid memory devices utilizing single level and multi-level memory cells. Logical addresses can be distributed between single level and multilevel memory cells based on a frequency of write operations performed. Initial storage of data corresponding to a logical address in memory can be determined by various methods including initially writing all data to single level memory or initially writing all data to multilevel memory. Other methods permit a host to direct logical address writes to single level or multilevel memory cells based on anticipated usage.

Hybrid memory management

Systems and methods are disclosed for command sets and functions for communication between and operation of devices, especially data storage devices. In an embodiment, an apparatus may comprise a data storage device configured to store data as objects, each object including a tracking indicator to identify the object, and a data field with a variable size to store user data. The data storage device may further be configured to receive a command including an operation directed to an object and an indicator that specifies a variation of the operation to be performed. In another embodiment, a memory device may store instructions that cause a processor to perform a method comprising storing data as objects to a nonvolatile media, and receiving a command including an operation directed to an object and an indicator that specifies a variation of the operation to be performed.

Devices for control of the operation of data storage devices using solid-state memory based on a discharge of an amount of stored energy indicative of power providing capabilities

A data storage device can include at least one non-volatile storage medium, at least one data cache, and a controller configured to perform cache writing operations between the at least one non-volatile storage medium and the at least one data cache based on user-selected caching modes. Also presented is a user interface that can be configured to selectively enable and disable one or more caching modes, which selection of a caching mode directs cache writing operations performed by a controller. In some examples, a caching mode can be selected in a manner that is independent of a host computer system.
