Optimized process for balancing load for data mirroring

A computer program product embodied in a tangible media comprising:

• computer readable program codes coupled to the tangible media for facilitating data transfers from a source node group to a target node group, the computer readable program codes configured to cause the program to:
• send from the source node group an initial selection request;
• and
• select a data sending node using a predefined source node selection policy, wherein the data sending node belongs to the source node group.

A system for facilitating data transfers between node groups, the system comprising:

• a target node group including a data receiving node;
• and
• tangible media coupled to computer readable program codes, the computer readable program codes configured to:
• send from the target node group an initial selection request;
• and
• select the data receiving node using a predefined target node selection policy.
