ABSTRACT:
An apparatus, system, and method are disclosed for coordinating storage requests in a multi-processor/multi-thread environment. A append/invalidate module generates a first append data storage command from a first storage request and a second append data storage command from a second storage request. The storage requests overwrite existing data with first and second data including where the first and second data have at least a portion of overlapping data. The second storage request is received after the first storage request. The append/invalidate module updates an index by marking data being overwritten as invalid. A restructure module updates the index based on the first data and updates the index based on the second data. The updated index is organized to indicate that the second data is more current than the first data regardless of processing order. The modules prevent access to the index until the modules have completed updating the index.
