Abstract

See full text

For efficient cache management of multi-target peer-to-peer remote copy (PPRC) modified sectors bitmap in a computing storage environment a multiplicity of PPRC modified sectors bitmaps are dynamically managed by placing the multiplicity of PPRC modified sectors bitmaps into slots of bind segments. One of the multiplicity of PPRC modified sectors bitmaps is set in one of the plurality of slots. Techniques are used depending on whether it is determined that one of the bind segments in the list of bind segments does not contain the free one of the multiplicity of slots.
