Appendix A Volume Construction & RAID
Configuration
• RAID1 mirroring volumes
Data can be exactly replicated to the Disk through this technique. If one Disk becomes
damaged in the volume, data can be efficiently transferred, saved and backed up to
another configured Disk. The volume's storage capacity is equal to that of the smallest
Disk in the RAID1, as the data is reproduced from Disk to Disk. The data backup is a priority
during RAID1. The saving of important data is recommended.
