A storage device includes: a storage controller to receive data from a host device, and to store the data in storage memory; and a reconfigurable integrated circuit communicably connected to the storage controller, and to accelerate logic operations executed on the data stored in the storage memory, the reconfigurable integrated circuit including: a first logic block to execute a static logic operation from among the logic operations; a second logic block to execute one or more dynamic logic operations from among the logic operations; and a plurality of memory buffers configured to store inputs and outputs of the first and second logic blocks.

Latency and throughput centric reconfigurable storage device

Disclosed herein are magnetic storage media with embedded disconnected circuits, and magnetic storage systems comprising such media. A magnetic storage media comprises a recording layer comprising a storage location, and an embedded disconnected circuit (EDC) configured to assist in at least one of writing to or reading from the storage location in response to a wireless activation signal. A magnetic storage system comprises a signal generator configured to generate a wireless activation signal, a magnetic storage media with a plurality of storage locations, and a write transducer and/or a read receiver. The magnetic storage media has at least one EDC configured to assist in writing to and/or reading from at least one of the plurality of storage locations in response to the wireless activation signal.

Embedded disconnected circuits in magnetic storage media of data storage devices

Disclosed herein are methods of using embedded disconnected circuits (EDC) in magnetic storage media to assist in reading data from and writing data to the magnetic storage media. A wireless activation signal is used to activate an EDC in a magnetic storage media. Once activated, the EDC may assist to record data in and/or read data from one or more memory locations of the magnetic storage media.

Methods of using embedded disconnected circuits in magnetic storage media of data storage devices

A host compiles code to perform a set of one or more database operations on target and embeds an indication of whether the target data is randomly accessed data or sequentially accessed data. The compiled code is transmitted to the compute engine inside a memory system that maintains a first portion of memory for storing sequentially accessed data and a second portion of memory for storing randomly accessed data. The memory system (e.g. SSD) maintains reduced size L2P tables in volatile working memory by maintaining coarse L2P tables in the working memory for use with sequentially accessed data and maintaining fine L2P tables in the working memory for use with randomly accessed data. The compute engine uses the compiled code to perform the set of one or more database operations on the target data using the working memory.

Hybrid logical to physical address translation for non-volatile storage devices with integrated compute module

A memory system (e.g. a solid state drive) includes one or more non-volatile memory die, a controller in communication with the memory die, a local memory connected to (or part of) the controller and a compute engine inside the memory system that is near the location of the data and can be used to perform common data manipulation operations. When the memory system receives instructions to use the compute engine to perform data manipulation operations, the local memory is reallocated such that an amount of space allocated in the local memory for logical to physical translation information is changed based on the one or more data manipulation instructions.

Non-volatile storage system with integrated compute engine and optimized use of local fast memory

A memory system (e.g. a solid state drive) includes one or more non-volatile memory die, a controller in communication with the memory die and a compute engine inside the memory system that is near the location of the data and can be used to perform common data manipulation operations.

Non-volatile storage system with compute engine to accelerate big data applications

Techniques are disclosed relating to writing data across multiple storage blocks in a storage device. In one embodiment, physical erase blocks in a bank of a storage device are erasable. Ones of the physical erase blocks may be associated with different respective communication channels. In such an embodiment, a data stripe may be written across a set of physical erase blocks such that the set of physical erase blocks includes physical erase blocks of different banks and includes physical erase blocks associated with different communication channels. In some embodiments, a request to read a portion of the data stripe may be received. In response to the request, a determination may be made that one of the set of physical erase blocks is unavailable to service the request. The request may then be serviced by reassembling data of the unavailable physical erase block.

Systems and methods for non-blocking solid-state memory

A system and method is described that accesses a network persistent memory unit (nPMU). One embodiment comprises a primary region corresponding to a predefined portion of a primary network persistent memory unit (nPMU) communicatively coupled to at least one client processor node via a communication system, wherein the primary region is assigned to a client process running on the client processor node and is configured to store information received from the client process; and a mirror region corresponding to a predefined portion of a mirror nPMU communicatively coupled to the client processor node via the communication system, wherein the mirror region is assigned to the client process and is configured to store the information received from the client process.

Communication-link-attached persistent memory system

A system is described that includes a network interface attached to a persistent memory unit. The persistent memory unit is configured to receive checkpoint data from a primary process, and to provide access to the checkpoint data for use in a backup process, which provides recovery capability in the event of a failure of the primary process. The network interface is configured to provide address translation information between virtual and physical addresses in the persistent memory unit. In other embodiments, the persistent memory unit is capable of storing multiple updates to the checkpoint state. The checkpoint state and the updates to the checkpoint state, if any, can be retrieved by the backup process periodically, or all at once upon failure of the primary process.

Persistent memory device for backup process checkpoint states

One embodiment of the present invention provides a distributed, differential electronic-data backup and archiving system that includes client computers and cells. Client computers execute front-end-application components of the distributed, differential electronic-data backup and archiving system, the front-end application components receiving data objects from client computers and sending the received data objects to cells of the distributed, differential electronic-data backup and archiving system for storage. Cells within the distributed, differential electronic-data backup and archiving system store the data objects, each cell comprising at least one computer system with attached mass-storage and each cell storing entire data objects as lists that reference stored, unique data chunks within the cell, a cell storing all of the unique data chunks for all data objects stored in the cell.

A switch is provided which may include a plurality of ports, a plurality of link up/down detection logic units and a configuration validation checker. Each link up/down detection logic unit may be associated with a port and may detect a change in the state of a link associated with the port. The configuration validation checker couples to each of the link up/down detection logic units and may cause the switch to change its routing behavior with regard to a port for which a link up/down detection unit has detected a state change.
