Abstract: Method and apparatus for managing data in a cloud computing environment. In accordance with some embodiments, data updates are received to a multi-tier memory structure across a cloud network and stored as working data in an upper rewritable non-volatile memory tier of the memory structure. The working data are periodically logged to a lower non-volatile memory tier in the memory structure while a current version of the working data remain in the upper memory tier. The upper and lower memory tiers each are formed of rewritable memory cells having different constructions and storage attributes.

Abstract: A memory controller manages memory access operations through a flash memory interface of a memory array of a solid-state storage device connected to a host. The memory controller executes a first memory access operation in the memory array. The first memory access operation has a first priority. The memory controller detects a suspending memory access operation available for execution in the memory array and having a higher priority than the first priority. The detection operation distinguishes between suspending memory access operations and non-suspending memory access operations. The memory controller suspends execution of the first memory access operation in the memory array and executes one or more memory access operations having higher priorities than the first priority and being available for execution in the memory array. The memory controller resumes the execution of the first memory access operation in the memory array.

Abstract: A definition is received of at least one data object and a compute object from a host at a storage compute device. A first key is associated with the at least one data object and a second key is associated with the compute object. A command is received from the host to perform a computation that links the first and second keys. The computation is defined by the compute object and acts on the data object. The computation is performed via the storage compute device using the compute object and the data object in response to the command.

Abstract: The disclosed technology provides for a solid state device that adaptively determines, responsive to receipt of a write command, whether or not to partition one or more individual logical blocks of data between multiple pages of a flash storage device. According to one implementation, the partitioning (e.g., spanning) determination is based on read frequency characteristics and the internal error correction code rate of the data.

Abstract: Computations are performed on data objects via two or more data storage sections. The data storage sections facilitate persistently storing the data objects in parallel read/write operations. The data objects are used in computations within a storage compute device. At least one of the storage sections is deactivated during the computations to reduce power usage of the storage compute device.

Abstract: An apparatus includes a controller capable of being coupled to a host interface and a memory device. The memory device includes two or more non-hierarchical, non-volatile memory units having different minimum addressable data unit sizes. The controller is configured to at least perform determining a workload indicator of a data object being stored in the memory device via the host interface. The controller selects one of the memory units in response to the workload indicator of the data object corresponding to the minimum addressable data unit size of the selected memory unit corresponding to the workload indicator. The data object is stored in the selected memory unit in response thereto.

Abstract: Parameters indicative of resistance variance of the memory elements are tracked. The resistance variance affects values of data stored in the resistance-based memory elements. A hash function is performed for each memory element. The hash function returns a reference to one of a plurality of counter elements. A value of each counter element is modified in response to the tracked parameter data of the associated memory element. Read operations affecting the memory elements are adjusted based on the values for the associated counter elements.

Abstract: Methods, apparatuses, and computer-readable media for providing extremely rapid preconditioning of an SSD. Upon receiving a precondition command from a host operably connected to the SSD to precondition a range of LBAs of the storage media, a plurality of physical units of the storage media to be preconditioned are determined based on the range of LBAs. A workload pattern is determined from the precondition command, and upon determining that the workload pattern indicates a random pattern, a valid page count for each of the plurality of physical units is computed based on a random distribution. Forward mapping table entries of a forward mapping table associated with the storage media corresponding to the range of LBAs is then populated with random physical addresses from the plurality of physical units based at least on the computed valid page count for each of the plurality of physical units.

Abstract: Systems and methods presented herein provide a controller is operable to increase a number of suspend operations during read Input/Output (I/O) operations of a storage device, and to detect an increase in response times for write commands due to the increased number of suspend operations. The controller is also operable to decrease the number of the suspend operations during the reads of the storage device to decrease the response times of the write commands.

Abstract: A storage compute device includes a data storage section that facilitates persistently storing host data as data objects. The storage compute device also includes two or more compute sections that perform computations on the data objects. A controller monitors resource collisions affecting a first of the compute sections. The controller creates a copy of at least one of the data objects to be processed in parallel at a second of the compute sections in response to the resource collisions.
