  • Patent number: 8112621
    Abstract: Even if each processor core uses the same logical address, a processing-target program corresponding to each processor core can be selected. A logical address of multiple address mapping tables is set to a same logical address in correspondence with an embedded OS program or a RAID management program, and a physical address is set to a different physical address in correspondence with the actual storage destination of an embedded OS program or a RAID management program. Each processor core, on start-up, uses a self address mapping table to execute address mapping processing with each processor core based on the same logical address, selects an embedded OS program or a RAID management program according to the physical address obtained in the address mapping processing, and executes processing according to the selected program.

  • Patent number: 8108644
    Abstract: The storage control apparatus of the present invention saves a table for managing a virtual volume in a pool and keeps the state of the table in the latest state. A first dynamic mapping table (DMT) that manages a first virtual volume is saved in a first pool. Upon receipt of a write command relating to an unused virtual slot from a write command issuing device, a first virtual volume control unit assigns an unused real slot in the first pool to the virtual slot and updates the first DMT. The first virtual volume control unit discriminates the validity of the received data and, in cases where “0” data are received, releases the assigned real slot, updates the first DMT once again, and discards the received data. In cases where the received data are valid data, de-staging is performed following a DMT update.
