In various embodiments, methods and systems for implementing distributed data object management are provided. The distributed data object management system includes a distributed storage system having a local metadata-consensus information store in and one or more remote metadata-consensus information stores. A metadata-consensus information store is configured to store metadata-consensus information. The metadata-consensus information corresponds to erasure coded fragments of a data object and instruct on how to manage the erasure coded fragments. The distributed storage system further includes a local data store and one or more remote data stores for the erasure coded fragments. The distributed data object management system includes a distributed data object manager for operations including, interface operations, configuration operations, write operations, read operations, delete operations, garbage collection operations and failure recovery operations. The distributed data object management system is operates based on metadata paths and data paths, operating in parallel, for write operations and read operations.

Distributed data object management system

In various embodiments, methods and systems for implementing distributed data object management are provided. The distributed data object management system includes a local metadata-consensus information store and one or more remote metadata-consensus information stores for metadata-consensus information and a local data store and one or more remote data stores for erasure coded fragments. For a write operation, corresponding metadata writes and data writes are performed in parallel using a metadata write path and a data write path, respectively, when writing to the local metadata-consensus information store and the one or more remote metadata-consensus information stores and the local data store and the one or more remote data stores. And, for a read operation, corresponding metadata reads and data reads are performed in parallel using a metadata read path and a data read path, respectively, when reading from the metadata-consensus information stores and the data stores.

Distributed data object management system operations

A data-storage system comprises a head receiver configured to variably receive up to a number M of write heads. The data-storage system also includes an installed number N of write heads arranged in the head receiver, a substrate receiver configured to receive one or more data-storage substrates, and a positioner machine configured to adjust a relative placement of each of the M write heads with respect to at least one of the one or more data-storage substrates.
