  • Systems and Methods for Persistent Address Space Management
    Publication number: 20190073296
    Abstract: Data is stored on a non-volatile storage media in a sequential, log-based format. The formatted data defines an ordered sequence of storage operations performed on the non-volatile storage media. A storage layer maintains volatile metadata, which may include a forward index associating logical identifiers with respective physical storage units on the non-volatile storage media. The volatile metadata may be reconstructed from the ordered sequence of storage operations. Persistent notes may be used to maintain consistency between the volatile metadata and the contents of the non-volatile storage media. Persistent notes may identify data that does not need to be retained on the non-volatile storage media and/or is no longer valid.
    Type: Application

  • Apparatus, system, and method for an address translation layer
    Patent number: 9690694
    Abstract: An apparatus, system, and method are disclosed for storage address translation. The method includes storing, in volatile memory, a plurality of logical-to-physical mapping entries for a non-volatile recording device. The method includes persisting a logical-to-physical mapping entry from the volatile memory to recording media of the non-volatile recording device. The logical-to-physical mapping entry may be selected for persisting based on a mapping policy indicated by a client. The method includes loading the logical-to-physical mapping entry from the recording media of the non-volatile recording device into the volatile memory in response to a storage request associated with the logical-to-physical mapping entry.
