    Abstract: Apparatus and method for executing hidden computational functions in a distributed data processing environment. In some embodiments, a trust boundary includes a target device such as a storage device, and a source device such as a client device in a computer network. A storage device processor executes a hidden command function (HCF) routine to accumulate HCF output data in a local cache responsive to an HCF command received from the client device over a data interface. The processor further establishes a smaller retention boundary within the trust boundary that includes the storage device and excludes the client device. The HCF output data are stored locally in a non-volatile memory (NVM) of the storage device while not transferring any portion of the HCF output data outside the retention boundary, including to the client device. The HCF routine can update a block-chain ledger or take some other form to provide data security.

    Abstract: A system includes a storage device and a computational storage processor. The storage device includes media. The computational storage processor is configured to, after issuance of a single command from a host device, receive data corresponding to the command, process the data as the data is received using a filter program and provide results data from the processed data.

    Abstract: Methods, apparatuses, and computer-readable media for streaming arbitrarily large amounts of data through computational storage programs of a computational storage device. A computational storage device comprises a storage media, a computational storage processor, and a controller. A firmware of the controller comprises a plurality of streaming drivers, each associated with a data source or data destination of the storage device. The firmware further comprises a buffer abstraction layer operable to read data from a data source through an associated ingress streaming driver of the plurality of streaming drivers to provide a source data stream for a computational storage program executing on the computational storage processor. The buffer abstraction layer is further operable to receive a destination data stream from the computational storage program and write data to a data destination through an associated egress streaming driver of the plurality of streaming drivers.

    Abstract: Apparatus and method for maintaining real-time coherency between a local cache of a target device and a client cache of a source device during execution of a distributed computational function. In some embodiments, a source device, such as a host computer, is coupled via a network interface to a target device, such as a data storage device. A storage compute function (SCF) command is transferred from the source device to the target device. A local cache of the target device accumulates output data during the execution of an associated SCF over an execution time interval. Real-time coherency is maintained between the contents of the local cache and a client cache of the source device, so that the client cache retains continuously updated copies of the contents of the local cache during execution of the SCF. The coherency can be carried out on a time-based granularity or an operational granularity.

    Abstract: A distributed data storage system can be configured with a host connected to a first device and an initialization module that performs a default initialization procedure on the first device in response to detecting the first device has an unknown manufacturing origin. Conducting the default initialization procedure may allow the first device to service data access requests from the host. In response to the connection of a second device to the host and initialization module, a manufacturing origin of the second device is identified with the initialization module before the initialization module customizes the default initialization procedure to a custom procedure that is executed to allow the second device to satisfy a background operation prescribed by the initialization module.
