Improved performance of dispersed location-based deduplication

A mechanism is provided for dispersed location-based data storage. A request is received to write a data file to a referrer memory region in a set of memory regions. For each data chunk of the data file, responsive to a comparison of a hash value for the data chunk to other hash values for other stored data chunks referenced in the referrer memory region indicating that the data chunk fails to exist in the referrer memory region, responsive to the data chunk existing in another memory region in the set of memory regions, responsive to the memory region failing to be one of the predetermined number N of owner memory regions associated with the referrer memory region, and responsive to the predetermined number N of owner memory regions failing to have been met, a reference to the data chunkis stored in the referrer memory region. 提供了一种用于基于分散位置的数据存储的机制。接收将数据文件写入一组存储器区域中的引用者存储器区域的请求。针对所述数据文件的每个数据块，响应于所述数据块的散列值与所述引用者存储器区域中所引用的其他所存储的数据块的其他散列值的比较指示所述数据块未存在于所述引用者存储器区域中，响应于所述数据块存在于该组存储器区域中的另一存储器区域中，响应于所述存储器区域未能成为与所述引用
