<strong>EC Storage Note:</strong>
|
|
EC volumes use erasure coding ({ fmt.Sprintf("%d+%d", erasure_coding.DataShardsCount, erasure_coding.ParityShardsCount) }) which stores data across { fmt.Sprintf("%d", erasure_coding.TotalShardsCount) } shards with redundancy.
|
|
Physical storage is approximately { fmt.Sprintf("%.1fx", float64(erasure_coding.TotalShardsCount)/float64(erasure_coding.DataShardsCount)) } the original logical data size due to { fmt.Sprintf("%d", erasure_coding.ParityShardsCount) } parity shards.
