Copy table size settings
Specify the parameters required to use (Remote) Advanced Copy. Decide these parameters by the copy capacity and the number of sessions (volumes) that will be run simultaneously, and then set them using the Web Console, ETERNUS Web GUI, or ETERNUS CLI.
Copy table size
The copy table size is the dedicated memory area required for Advanced Copy management. Please allocate in advance.
Resolution
The 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.
Please estimate by 1 time as much as possible.
