Efficient free-space management of multi-target peer-to-peer remote copy (PPRC) modified sectors bitmap in bind segments
Abstract:
For efficient free-space management of multi-target peer-to-peer remote copy (PPRC) modified sectors bitmap in bind segments, maintaining a list of bind segments having a free slots for each storage volume. Each one of the bind segments includes a bitmap of the free slots. The bind segments are used to store a plurality of PPRC modified sectors bitmaps as needed, where all of the bind segments have a header and a plurality of free slots to store the plurality of PPRC modified sectors bitmaps.
