Method and apparatus for managing autonomous third party data transfers

A method for managing autonomous third party data transfers between a source storage device and a destination storage device, comprising:

• determining a segment size for an autonomous data transfer, the segment size based on a data capacity of a data mover conducting the autonomous data transfer, and selected such that each segment ends on a block boundary of the destination storage device;
• dividing the autonomous data transfer into segments according to the segment size;
• and
• executing an autonomous data transfer for each segment.

An apparatus for managing autonomous third party data transfers between a source storage device and a destination storage device, comprising:

• means for determining a segment size for an autonomous data transfer that includes source data blocks and embedded metadata data blocks of different sizes, the segment size based on a data capacity of a data mover conducting the autonomous data transfer, and selected such that each segment ends on a block boundary of the destination storage device;
• means for dividing the autonomous data transfer into segments according to the segment size;
• and
• means for executing an autonomous data transfer for each segment.

An article of manufacture comprising a program storage medium readable by a processor and embodying one or more instructions executable by a processor to perform a method for managing autonomous third party data transfers between a source storage device and a destination storage device, the method comprising:

• determining a segment size for an autonomous data transfer, the segment size based on a data capacity of a data mover conducting the autonomous data transfer, and selected such that each segment ends on a block boundary of the destination storage device;
• dividing the autonomous data transfer into segments according to the segment size;
• and
• executing an autonomous data transfer for each segment.
