Abstract:
For combining virtual mapping metadata and physical space mapping metadata in a storage system by a processor device in a computing environment, data and metadata are maintained into separate virtual streams. The separate virtual streams include a metadata stream for the metadata and a data stream for the data. Information of a mapping of logical data to a location on the data stream and a current state of unused spaces in the data stream is linearly distributed within the metadata stream.
