Abstract:
A method for controlling data for a storage system comprises: receiving a write input/output (I/O) command of a data from a host computer, the write I/O command including an application ID identifying an application operating on the host computer which sends the write I/O request; maintaining a record of a relation between the application ID in the write I/O command and a storage location of the data to be written in a first volume of the storage system; determining, based on the application ID, whether a data transfer function between the first volume and a second storage volume is to be performed on the data beyond writing the data to the storage location in the first volume; and if the data transfer function is to be performed on the data, then performing the data transfer function on the data to the second volume.
