Claim:
A data storage system comprising: a storage server operable to process an I/O write command and a point-in-time copy command each with respect to first data associated with a logical storage volume; in-band I/O channels; multiple physical source volumes in communication with the storage server through the in-band I/O channels, each physical source volume capable of being established in a point-in-time copy relationship with one of corresponding multiple physical target volumes; a logical volume manager associated with the storage server operable to parallelize the first data and distributing a portion of the first data over one of the in-band I/O channels for writing to each of the multiple physical source volumes in a striped fashion, the logical volume manager being further operable to distribute the point-in-time copy command to each of the physical source volumes over one of the in-band I/O channels, whereby execution of the point-in-time copy command is completed by one of the physical source volumes prior to the second data being stored to the one of the multiple physical source volumes to update the first data.
