Abstract: One embodiment facilitates atomicity assurance for storing data and metadata in a data stream. The system receives a first stream of data to be written to a storage device, wherein the first stream includes a plurality of I/O requests associated with data and corresponding metadata. In response to determining that residual data associated with a preceding I/O request of the first stream exists in a data buffer: the system appends, to the residual data, a first portion of data from a current I/O request to obtain a first page of data; the system writes a remainder portion of the current I/O request to the data buffer to obtain current residual data; and the system writes the first page of data to the storage device. Thus, the system thereby facilitates atomicity assurance for storing the data and corresponding metadata of each I/O request of the first data stream.

Abstract: Systems, methods, and apparatus are provided for iteratively decoding a codeword. Once a codeword is received, the codeword is processed to generate an incremental hard decision value and a log likelihood ratio amplitude value. These values are generated by processing the codeword using a soft output Viterbi algorithm. A faulty symbol in the codeword is identified. A complete hard decision value is generated using the incremental hard decision value. The LLR amplitude value and complete hard decision value corresponding to the identified faulty symbol are selectively provided to a decoder and the decoder uses these values to decode the codeword.

Abstract: Embodiments described herein provide a system for facilitating a lightweight distributed storage system. During operation, the system generates a data segment from a data file associated with a write operation and determines a storage key for the data segment. The storage key indicates a calculated storage path associated with a replica of the data segment. The system then determines whether a user-defined storage path is specified by a user for the data segment. If a user-defined storage path has not been specified by the user for the data segment, the system generates a data packet comprising the data segment, wherein a destination for the data packet corresponds to a target disk specified by the calculated storage path.

Abstract: One embodiment facilitates a user-space storage I/O stack. During operation, the system generates, by a file system in the user-space, a logical block address associated with an I/O request which indicates data to be read or written. The system generates, by a flash translation layer module in the user-space, a physical block address corresponding to the logical block address, wherein the flash translation layer module is located between the file system and a block device driver in the user-space. The system estimates a latency associated with executing the I/O request. In response to determining that the estimated latency is greater than or equal to a predetermined threshold, and that the I/O request is a read request, the system reads the requested data from a location other than the physical block address.

Abstract: Embodiments of the present invention provide flash-based storage with non-volatile memory components. MRAM is mainly used as a data buffer, and NOR flash is used to store metadata, such as FTL information, thereby providing non-volatile storage and significantly simplifying power failure mitigation. MRAM and NOR are jointly used to share the work performed by DRAM in existing SSDs based on the characteristics of the data stored, reducing the power consumption and cost of the SSD. The cache fault rate is reduced because both MRAM and NOR are immune from soft errors. Moreover, the working mechanisms are simplified and the power-up duration is significantly reduced because less data is copied from NAND flash, as there is no need to move all of the FTL information back to NAND flash at power off.
