OPTIMIZING PEER-TO-PEER REMOTE COPY (PPRC) TRANSFERS FOR PARTIAL WRITE OPERATIONS |
| 摘要 |
For optimizing peer-to-peer remote copy (PPRC) transfers for partial write operations in a computing storage environment by a processor device by maintaining a PPRC modified sectors bitmap in bind segments upon demoting a track out of a cache for transferring a partial track after the demoting the track, wherein a hash table is used for locating the PPRC modified sectors bitmap. |

1. A method for optimizing peer-to-peer remote copy (PPRC) transfers for partial write operations in a computing storage environment by a processor device, comprising:
maintaining a PPRC modified sectors bitmap in bind segments upon demoting a track out of a cache for transferring a partial track after the demoting the track, wherein a hash table is used for locating the PPRC modified sectors bitmap. |
