It is now common practice to estimate the data size recognized by the transaction server to recognize, use, and create its volume, and accordingly allocate a logical unit (LUN) from the disk unit. VSC provides a virtual disk function that allows you to create a volume of a size independent of the logical unit (LUN) size. In other words, this function weakens the physical relationship between a transaction server and disk unit, and makes it possible to provide a volume of the desired size at the desired time for the transaction server.
You can combine more than one physical disk to create one virtual disk.
You can split one physical disk to create more than one virtual disk.
You can also expand the size of a virtual disk itself.
You can create virtual disks in batch processing while retaining existing data required by users. For more information, refer to "5.1.8 Batch conversion".
