Appendix A Volume Construction & RAID
Configuration
• RAID10 Mirroring & striping volumes
In relation to the volume configuring techniques RAID1 and RAID0, the Disks are
configured 2 at a time by RAID1, followed by the configured set being associated
by RAID0 and hence the volume as a whole is configured. With more than 4 Disks
present, configuration occurs in pairs. 4 Disks are used to configure the LG Network
Storage.
If Disk damage does not happen simultaneously to 2 Disks configured through
RAID1, the volume will continue to function. The volume save capacity is equal to
the product of the minimum Disk capacity and half of the number of Disks in the
volume.
Data backup and the safeguarding of saving capacity occur simultaneously. (RAID5
prioritizes capacity security, where RAID10 prioritizes data backup).
