In distributed storage systems,an efficient multi-node regenerating program with healthy nodes collaboration was proposed to make a trand-off between the repair bandwidth and reliability for multi-node regeneration. Specific multi-node repair process and the construction of regenerating code were introduced,and the max-flow-min-cut of information flow graph was used to illustrate its lower bound. It is shown that the program ensures the repair bandwidth maintain to minimum during the repair process,and makes the repair time synchronization and repair process easier. The most important is less that of desired transmission channels when ensuring reliability of regeneration.
