Abstract:
Scale out data protection with erasure coding is presented herein. Based on an initial number of storage devices determined to have been included in an initial stage of a data storage cluster, an initial protection scheme for the initial stage can determine first coding fragment(s) for data stored within the data storage cluster to facilitate a first recovery, from the initial stage, of the data using the first coding fragment(s). Further, in response to a defined number of additional storage devices being determined to have been added to the data storage cluster to generate a modified data storage cluster, the initial protection scheme can be modified to obtain a modified protection scheme that can determine, for the modified data storage cluster, second coding fragment(s) for the data to facilitate a second recovery of the data using the first coding fragment(s) and the second coding fragment(s).

Claim (Index 10):
A method, comprising:\n determining, by a system comprising a processor, a target protection scheme for a data storage cluster, wherein the target protection scheme corresponds to a target coding matrix for data that has been stored within the data storage cluster; based on an initial number of storage devices that have been included in an initial stage of the data storage cluster, determining, by the system, an initial protection scheme for the initial stage of the data storage cluster comprising determining a first portion of coefficients of the target coding matrix to facilitate a first recovery, from the initial stage of the data storage cluster, of a lost portion of the data; and in response to determining that a defined number of additional storage devices have been added to the data storage cluster to generate a modified data storage cluster, modifying, by the system, the initial protection scheme to obtain a modified protection scheme for the modified data storage cluster, wherein the modified protection scheme comprises determining a second portion of coefficients of the target coding matrix that is different than the first portion of coefficients, and wherein the first portion of coefficients and the second portion of coefficients facilitate a second recovery, from the modified data storage cluster, of the lost portion of the data.
