A storage device. In some embodiments the storage device includes a storage controller; a nonvolatile memory device connected to the storage controller through a first physical interface, and a processing circuit. The processing circuit may be connected, through a second physical interface, to the storage controller or to the nonvolatile memory device, the second physical interface being the same as the first physical interface.

Heterogeneous in-storage computation

A method of facilitating communication to an embedded computer in a computational storage device via a host includes receiving a message for transmission to an embedded process running at the embedded computer, determining that a destination address of the message corresponds to the embedded computer within the computational storage device, in response to the determination, forwarding the message to a host relay process associated with the embedded computer, and encapsulating the message to generate a proprietary command for transmission to the computational storage device.

System and method for computational storage device intercommunication

A method of computational storage device intercommunication includes receiving a notification from a first storage controller of a first computational storage device indicating a presence of a message, in response to receiving the notification, transmitting a send message request to the first storage controller of the first computational storage device, and receiving the message from the first storage controller, storing the message to a host memory and notifying a host pseudo network device driver of availability of the message, determining whether a destination address of the message corresponds to a host user process that is local to the host or to a second user process that is local to a second embedded computer of a second computational storage device, and providing the message to the host user process or to the second embedded computer associated with the destination address.

System and method for communicating between computational storage devices

A storage device. In some embodiments, the storage device includes a storage interface, configured to be connected to a host computer, a processing circuit, and persistent storage media. The processing circuit may be configured to: read first data from the persistent storage media in response to a read command received through the storage interface; transmit second data through the storage interface, the second data being based on the first data; receive a write command, with third data, through the storage interface; write fourth data, based on the third data, to the persistent storage media; and perform a cryptographic operation on the first data or on the third data.

SSD content encryption and authentication

A method of facilitating communication from an embedded computer in a computational storage device to a host or an external device includes receiving a message from an embedded user process for transmission to a user process running at either the host or the external device, determining that a destination address of the message corresponds to the host or the external device, in response to the determination, forwarding the message to an embedded relay process associated with the host or the external device, instructing a storage controller of the computational storage device about the message to be delivered, notifying a host relay process at the host of a presence of the message, receiving a send message request from the host in response to the notification, and in response to receiving the send message request, transmitting the message to the host.

System and method for outward communication in a computational storage device

A system and methods for in-storage on-demand data decompression. Compressed data are stored in a storage device connected to a host computer. When decompressed data are needed, the host computer sends a decompression command to the storage device indicating which data are to be decompressed, and instructing it how to decompress the data. The storage device decompresses the data and stores the decompressed data, making it available to the host.

System and methods for in-storage on-demand data decompression

A system and method for providing consistent performance in a storage device, such as a solid state drive. A threshold value for command execution time for a command in a category of command (e.g., a read command or a write command) and a command size, is stored in the storage device. When a host command in the category (e.g., a read command) and corresponding size is received, the storage device executes the command, and if it completes execution of the command in a time that is less than the threshold value, the solid state drive waits until an amount of time equal to the threshold value has elapsed before sending the command completion.

System and method for consistent performance in a storage device

A system and method of providing enhanced data processing and analysis in an infrastructure for distributed computing and large-scale data processing. This infrastructure uses the Apache Spark framework to divide an application into a large number of small fragments of work, each of which may be performed on one of a large number of compute nodes. The work may involve Spark transformations, operations, and actions, which may be used to categorize and analyze large amounts of data in distributed systems. This infrastructure includes a cluster with a driver node and a plurality of worker nodes. The worker nodes may be, or may include, intelligent solid state drives capable of executing data processing functions under the Apache Spark framework. The use of intelligent solid state drives reduces the need to exchange data with a central processing unit (CPU) in a server.
