Abstract
According to one embodiment, a computer-implemented method includes determining a write speed for each of a plurality of systems in a cluster, determining a ratio of the write speeds for each of the plurality of systems in the cluster, and updating parity assignments to each of the plurality of systems in the cluster, based on the ratio of the write speeds.
Claims20
A computer-implemented method, comprising:
- determining a write speed for each of a plurality of systems in a cluster;
- determining a ratio of the write speeds for each of the plurality of systems in the cluster;
- and
- updating parity assignments to each of the plurality of systems in the cluster, based on the ratio of the write speeds.
A computer program product for implementing a write-balanced parity assignment within a cluster, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:
- determining, by the processor, a write speed for each of a plurality of systems in the cluster;
- determining, by the processor, a ratio of the write speeds for each of the plurality of systems in the cluster;
- and
- updating, by the processor, parity assignments to each of the plurality of systems in the cluster, based on the ratio of the write speeds.
A system, comprising:
- a processor;
- and
- logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
- determine a write speed for each of a plurality of systems in a cluster;
- determine a ratio of the write speeds for each of the plurality of systems in the cluster;
- and
- update parity assignments to each of the plurality of systems in the cluster, based on the ratio of the write speeds.
