Abstract: Systems and methods for prefetching data are disclosed. A processor in communication with a storage device identifies a first address. The processor identifies a first setting associated with the first address. The processor issues a first command to a first storage medium of the storage device based on the first setting. The first command is for performing a first type of memory read. The storage device is configured to retrieve first data associated with the first address in the first storage medium, to a second storage medium of the storage device, based on the first command.

Abstract: An accelerator is disclosed. A circuit may process a data to produce a processed data. A first tier storage may include a first capacity and a first latency. A second tier storage may include a second capacity and a second latency. The second capacity may be larger than the first capacity, and the second latency may be slower than the first latency. A bus may be used to transfer at least one of the data or the processed data between the first tier storage and the second tier storage.

Abstract: A method includes sending, from an application layer, a chunk size setting to an erasure coding layer. The method further includes receiving, at the application layer, user data. The method further includes aligning, at the application layer, the user data based on the chunk size setting. The method further includes sending the aligned user data to the erasure coding layer. The method further includes partitioning, at the erasure coding layer, the aligned user data into a first data chunk and a second data chunk. The method further includes generating, at the erasure coding layer, a parity chunk based on the first data chunk and the second data chunk. The method further includes sending, from the erasure coding layer, the first data chunk, the second data chunk, and the parity chunk to a storage system.

Abstract: According to one general aspect, an apparatus may include a regeneration-code-aware (RCA) storage device configured to calculate at least one type of data regeneration code for data error correction. The RCA storage device may include a memory configured to store data in chunks which, in turn, comprise data blocks. The RCA storage device may include a processor configured to compute, when requested by an external host device, a data regeneration code based upon a selected number of data blocks. The RCA storage device may include an external interface configured to transmit the data regeneration code to the external host device.

Abstract: Systems and methods for prefetching data are disclosed. A processor executes a first command for moving first data stored in a storage device. Based on the first command, the processor stores, into a first queue of the storage device, a first address associated with the first data. The storage device further retrieves the first address from the first queue, retrieves the first data from the first storage medium based on the first address, and stores the first data to the second storage medium. In some embodiments, a process for prefetch optimization is also disclosed. A processor identifies a value for prefetching data. The processor runs an application, measures performance of the application, modifies the value based on the performance, and determines that the performance satisfies a criterion.
