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 16):
A machine-readable storage medium comprising instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:\n determining a target protection scheme for a data storage cluster, wherein the target protection scheme corresponds to a defined upper limit of coding fragments for data that has been stored within the data storage cluster; based on an initial number of storage devices that have been determined to have been included in an initial stage of the data storage cluster, determining an initial protection scheme for the initial stage of the data storage cluster comprising determining a first portion of the coding fragments to facilitate a first recovery, from the initial stage of the data storage cluster, of the data; and in response to a defined number of additional storage devices being determined to have been added to the data storage cluster to obtain a modified data storage cluster, modifying 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 the coding fragments that is different than the first portion of the coding fragments, and wherein the first portion of the coding fragments and the second portion of the coding fragments facilitate a second recovery, from the modified data storage cluster, of the data.
