Intelligent Selection of Replication Node for File Data Blocks in GPFS-SNC

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• write a file at an owner node within a plurality of nodes in a data processing system;
• divide the file into a plurality of file chunks;
• identify at least one replication node within the plurality of nodes having a duplicate copy of a respective file chunk within the plurality of file chunks;
• select a plurality of replication nodes for the plurality of file chunks based on identification at least one replication node within the plurality of nodes having a duplicate copy of a respective file chunk;
• and
• replicate the file at the plurality of replication nodes based on the selection of the plurality of replication nodes.

An apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• write a file at an owner node within a plurality of nodes in a data processing system;
• divide the file into a plurality of file chunks;
• identify at least one replication node within the plurality of nodes having a duplicate copy of a respective file chunk within the plurality of file chunks;
• select a plurality of replication nodes for the plurality of file chunks based on identification at least one replication node within the plurality of nodes having a duplicate copy of a respective file chunk;
• and
• replicate the file at the plurality of replication nodes based on the selection of the plurality of replication nodes.
