A system and method for executing user-provided code securely on a solid state drive (SSD) to perform data processing on the SSD. In one embodiment, a user uses a security-oriented cross-compiler to compile user-provided source code for a data processing task on a host computer containing, or otherwise connected to, an SSD. The resulting binary is combined with lists of input and output file identifiers and sent to the SSD. A central processing unit (CPU) on the SSD extracts the binary and the lists of file identifiers. The CPU obtains from the host file system the addresses of storage areas in the SSD containing the data in the input files, reads the input data, executes the binary using a container, and writes the results of the data processing task back to the SSD, in areas corresponding to the output file identifiers.

System and method for executing native client code in a storage device

A system and method for combining the execution of a query with other operations, such as a data retention scan, in a storage device, when the execution of the query is not time-sensitive. The storage device may be connected to a host, and may operate during intervals of time in a power save mode. When a query is received by the host that is not time-sensitive, the query may be stored in the host or in the storage device until such time as the device would otherwise return to a normal operating mode, and then the query may be executed. Such delayed execution may enable the sharing of read operations for the query with read operations used, for example, for the execution of other queries or for a data retention scan.

Power efficient method and system for executing host data processing tasks during data retention operations in a storage device

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 for comparing a character from a search space simultaneously to each of a set of search characters. The set of search characters may correspond to a regular expression. In one embodiment, the search space character is encoded to a short binary presentation (e.g., to an 8-bit representation), which is then converted to a long binary representation one bit of which is set, at a first position in the long binary representation corresponding to the value of the short representation. Each character of the set of search characters is similarly encoded and converted to a respective long binary representation. If the bit in one of the long binary representations corresponding to the set of search characters is set, it indicates that the search character matches the corresponding character of the set of search characters.
