Abstract: Embodiments of the invention include a method, apparatus and system for storing data that involves storing boundary information for data that is being written to a plurality of data storage devices. The method includes storing boundary information for a write operation of data to a plurality of data storage device, writing the data to the plurality of data storage devices and removing the recorded boundary information upon completion of the write operation of the data to the plurality of data storage devices. The boundary information can indicate the data storage device regions where particular sets of data are to be written during the write operation. If an interruption occurs during the write operation, the boundary information can be used to recover from the interruption by identifying the specific data storage device region or regions where data was being written when the interruption occurred.
