Method of hashing address space to storage servers

摘要

An embodiment of a method of hashing an address space to a plurality of storage servers begins with a first step of dividing the address space by a number of the storage servers to form data segments. Each data segment comprises a base address. A second step assigns the data segments to the storage servers according to a sequence. The method continues with a third step of measuring a load on each of the storage servers. According to an embodiment, the method concludes with a fourth step of adjusting data shares assigned to the storage servers according to the sequence to approximately balances the loads on the storage servers while maintaining the base address for each data segment on an originally assigned storage server. According to another embodiment, the method periodically performs the third and fourth steps to maintain an approximately balanced load on the storage servers.
