Abstract:
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.
