Abstract
A computer-implemented method, according to one embodiment, includes: receiving a write request at a storage system which includes more than one storage device, determining a storage location for data included in the write request, and determining a storage location for parity information corresponding to the data included in the write request. A first copy of the data included in the write request is sent to a first storage device which corresponds to the storage location for the data included in the write request. Moreover, a second copy of the data included in the write request is sent to a second storage device which corresponds to the storage location for the parity information. One or more instructions to compute the parity information via a decentralized communication link with the remaining storage devices are sent to the second storage device. The first storage device is different than the second storage device.
