| 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. | ||

| 主权项 | 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; and resetting the PPRC modified sectors bitmap if the track is full and all bits in the PPRC modified sectors bitmap are set. | ||
