Abstract
The technology disclosed herein includes a method for dividing a body of user data into a plurality of data blocks, and writing the plurality of data blocks into chunk zones in parallel streams, the chunk zones located in a first ordered pool of storage devices. In some implementations, the method includes adding additional storage devices to the first ordered pool making a second ordered pool, including the first ordered pool, and writing the plurality of data blocks across the second ordered pool of storage devices, such that each of the storage devices including spare capacity. The method includes determining if a storage device fails, and seeking data for the data blocks on the failed storage device from of the other storage devices.
