Publication number: 20190181887Abstract: Methods and systems for improving the read and write performance of a distributed file system while limiting memory usage are described. The type of error correcting scheme applied to data, the partitioning of the data into data chunks, and the sizes of data slices within each of the data chunks used for storing electronic files within the distributed file system may be dynamically adjusted over time to optimize for fast IO performance while limiting memory usage (e.g., requiring less than 256 MB of RAM to generate and store code blocks). The file size of an electronic file to be stored, the amount of available memory for generating code blocks, and the amount of available disk space to store the electronic file may be used to set the data sizes of the data slices and the type of erasure code applied to data blocks associated with the data slices.Type: ApplicationFiled: December 11, 2017Publication date: June 13, 2019Applicant: RUBRIK, INC.Inventors: Arijit Banerjee, Garvit Juniwal, Adam Gee

Patent number: 9411668Abstract: A subsystem is configured to apply an offset voltage to a test, or canary, SRAM write driver circuit to create a condition that induces failure of the write operation. The offset voltage is incrementally increased until failure of the test write operation occurs in the canary SRAM circuit. The subsystem then calculates a probability of failure for the actual, non-test SRAM write operation, which is performed by an equivalent driver circuit with zero offset. The subsystem then compares the result to a benchmark acceptable probability figure. If the calculated probability of failure is greater than the benchmark acceptable probability figure, corrective action is initiated. In this manner, actual failures of SRAM write operations are anticipated, and corrective action reduces their occurrence and their impact on system performance.Type: GrantFiled: January 14, 2014Date of Patent: August 9, 2016Assignee: NVIDIA CorporationInventors: Arijit Banerjee, Mahmut Ersin Sinangil, John W.
