Abstract: A system and method for an LBA RAID storage device. The LBA RAID storage device includes a plurality of data channels and a plurality of storage components. Each of the storage components is connected to one of the plurality of data channels. A storage controller is configured to receive a data and write the data to a RAID group made up of at least two storage components of the plurality of storage components that are each connected to a separate data channel.

Abstract: In a method for training a machine learning model, the method includes: segmenting, by a processor, a dataset from a database into one or more datasets based on time period windows; assigning, by the processor, one or more weighted values to the one or more datasets according to the time period windows of the one or more datasets; generating, by the processor, a training dataset from the one or more datasets according to the one or more weighted values; and training, by the processor, the machine learning model using the training dataset.

Abstract: A method for predicting a time-to-failure of a target storage device may include training a machine learning scheme with a time-series dataset, and applying the telemetry data from the target storage device to the machine learning scheme which may output a time-window based time-to-failure prediction. A method for training a machine learning scheme for predicting a time-to-failure of a storage device may include applying a data quality improvement framework to a time-series dataset of operational and failure data from multiple storage devices, and training the scheme with the pre-processed dataset. A method for training a machine learning scheme for predicting a time-to-failure of a storage device may include training the scheme with a first portion of a time-series dataset of operational and failure data from multiple storage devices, testing the machine learning scheme with a second portion of the time-series dataset, and evaluating the machine learning scheme.

Abstract: A system and method for processing source data are disclosed. A first node receives from a second node, a request for the source data. The first node generates and returns, in response to the request, an output partition of the source data. The generating and returning of the output partition include generating a first child partition from parent input data, and generating and returning, as the output partition, a first grandchild partition from the first child partition. The first node also generates a second child partition from the parent input data.

Abstract: In a method for dynamic wear-levelling and load redirection in a solid-state drive (SSD) including one or more blocks, the method including: receiving, by a controller, a request to write data; calculating, by the controller, a vulnerability factor of the one or more blocks; selecting, by the controller, a target block from the one or more blocks to receive the request to write data; determining, by the controller, a status of the target block based on the vulnerability factor of the target block; writing, by the controller, the data to the target block based on the status of the target block; and updating, by the controller, a mapping table based on the data written to the target block.
