Abstract
Techniques for faster reconstruction of segments using a dedicated spare memory unit are described. Zone segments in memory units are associated with a dedicated spare memory unit. The zone segments are reconstructed in the dedicated spare memory unit in response to a failed memory unit except for an identified failed zone segment of the failed memory unit. The identified failed zone segment of the failed memory unit is retained in the dedicated spare unit. Other embodiments are described and claimed.
Claims20
A computer-implemented method, comprising:
- segmenting a memory unit into a plurality of zone segments;
- associating the plurality of zone segments with a dedicated spare memory unit assigned to a memory unit group;
- and
- reconstructing, in the dedicated spare memory unit, each one of the plurality of zone segments in response to a failed memory unit except for an identified failed zone segment of the failed memory unit.
A system, comprising:
- a plurality of memory units;
- a memory unit group including the plurality of memory units;
- and
- at least one processor device, in communication with the memory unit group, operable in the computing storage environment, wherein the at least one processor device:
- splits each one of the plurality of memory unit into a plurality of zone segments;
- associates the plurality of zone segments with a dedicated spare memory unit;
- and
- reconstructs, in the dedicated spare memory unit, each one of the plurality of zone segments in response to a failed memory unit except for an identified failed zone segment of the failed memory unit.
At least one non-transitory computer-readable storage medium comprising instructions that, when executed, cause a system to:
- associate a plurality of zone segments in a plurality of memory units with a dedicated spare memory unit;
- and
- reconstruct, in the dedicated spare memory unit, each one of the plurality of zone segments in response to a failed memory unit except for an identified failed zone segment of the failed memory unit, wherein the identified failed zone segment of the failed memory unit is retained in the dedicated spare unit.
