  • STRIPING DATA ACROSS ERASE BLOCKS HAVING DIFFERING SIZES
    Publication number: 20240004568
    Abstract: A method of operating a storage system having solid-state storage memory with segment level heterogeneity is provided. The method includes mapping data into data segments, and mapping the data segments into data stripes. The method includes writing a first data stripe from a first data segment across a first plurality of blades of the storage system comprising heterogeneous total amounts of the solid-state storage memory per blade, and writing a second data stripe from the first data segment across a second plurality of blades of the storage system.
    Type: Application

  • Adaptive forward error correction (FEC) in passive optical networks (PONs)
    Patent number: 9942003
    Abstract: An apparatus in a network such as an optical passive network (PON) includes a first decoder configured to decode an encoded data signal using a first code to generate a decoded signal. When the encoded data signal comprises unknown information that was not successfully decoded by the first decoder and would otherwise be ignored, the unknown information is included in the decoded signal. The apparatus may further include a second decoder configured to decode the decoded signal using a stronger code than the first code.
