Abstract: Methods and devices are provided in which a controller (706) of a storage device (704) receives a read command including at least a file pointer of a file, from an application at a host device (702). The controller (706) retrieves a physical block address (PBA) list associated with file data from a table maintained at the controller (706) using the file pointer. The controller (706) reads data from a memory using the PBA list, and provides the file data to the application at the host device (702).

Abstract: A storage device is disclosed. The storage device may include at least one controller for a virtual machine (VM) (305) that is on a source host (105-1). Storage in the storage device may store data for the VM (305). A second storage may store a storage state (410) for the VM (305). A storage device controller (405) may process at least one read request received from the controller for the VM (305) using the first storage and at least one write request received from the controller for the VM (305) using the first storage. A VM migration state monitor and capture module (415) may assist in the migration of the VM (305) from the source host (105-1) to a destination host (105-2).

Abstract: Systems and methods for executing a data processing function are disclosed. A first processing device (200a) of a storage accelerator (112) loads a first instruction set associated with a first application of a host computing device. A second processing device (200b) of the storage accelerator (112) loads a second instruction set associated with the first application. A command is received from the host computing device. The command may be associated with data associated with the first application. The first processing device (200a) identifies at least a first criterion or a second criterion associated with the data. The first processing device (200a) processes the data according to the first instruction set in response to identifying the first criterion. The first processing device (200a) writes the data to a buffer of the second processing device (200b) in response to identifying the second criterion. The second processing device (200b) processes the data in the buffer according to the second instruction set.

Abstract: A method may include receiving, at a storage device, a command for a data transfer between the storage device and a host, determining a specified data rate for the data transfer, and performing the data transfer between the storage device and the host based on the command, wherein the storage device may control the data transfer based on the specified data rate. The data transfer may include a peak portion and an idle portion. The method may further include controlling, at the storage device, a peak portion and an idle portion of the data transfer based on the specified data rate. The method may further include controlling, at the storage device, the data transfer based on a peak burst size. The specified data rate may be received from the host and/or determined by the storage device by monitoring one or more parameters of a data transfer.

Abstract: Systems and methods for processing storage transactions are disclosed. A transaction between a storage device (102) and a host computing device (100) comprising a plurality of memory subsystems is identified. The storage device (102) determines that the transaction satisfies a criterion, wherein the criterion is satisfied in response to identifying the type of the transaction as a transaction for writing data retrieved from the storage device, or for writing input/output command completion related data structures, and, in response, inserts data into a packet associated with the transaction. The data identifies a corresponding memory subsystem of the plurality of memory subsystems. The storage device (102) transmits the packet, including the data, to the host computing device (100) and the packet is stored in the memory subsystem based on the data.
