In other words, the control module stores the bitmap for the managed LUN in a bitmap storage unit. A mirror LUN control unit sets a corresponding portion of the bitmap to 1, controls data write to a target segment and a mirror segment, and resets the bitmap to 0 when the data write to both of the segments is complete. A resynchronization control unit refers to the bitmap storage unit to perform the resynchronization processing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage control device and storage system","description":"A control module that manages a segment to which data is written implements write processing and resynchronization processing using a bitmap managed for each LUN.
