Parameter settings
Specify the parameters required to use (Remote) Advanced Copy. These parameters can be set by ETERNUS Web GUI/ETERNUS CLI or Express.
Resolution is the value that determines the amount of data each bit in the copy bitmap represents. The allowed resolution settings of "1 (standard)", "2", "4", "8", and "16" respectively give 8KB, 16KB, 32KB, 64KB, and 128KB regions of data per bitmap bit. The same value is used in the ETERNUS Disk storage system. The smallest possible resolution value should be set, to reduce the internal process overhead.
Table size is the dedicated memory area required for Advanced Copy management. The table size and resolution settings are determined by the copy capacity and the number of sessions (volumes) that will be run simultaneously.
