4.1.4.5 RAID Manager
RAID (redundant array of independent disks) is a data storage virtualization technology that
combines multiple physical HDD components into a single logical unit for the purposes of data
redundancy, performance improvement, or both. Not all NVRs have this feature.
RAID function is for some series products only. A slight difference may be found in the user
interface.
When setting HDDs in a RAID array make sure to set a hotspare.
All data on the HDDs will be deleted when creating or removing a RAID group.
It is recommended to have your HDDs placed into multiple RAIDs instead of one large RAID.
In the table below the number without "()" represents the disk number of the RAID group. The
number with () represents the number of global hot spare disks. For example, for 24 HDD, the
setup strategy is 7+7+9+(1). It means three RAID 5 and one hot spare, and each RAID 5
respectively contains 7 disks, 7 disks, and 9 disks.
It is recommended that you have 1 hot spare per RAID group. In the event, the 1 hot spare is
being used for another RAID group that had a drive fail if a drive fails in the 2nd or 3rd RAID
group but no hot-spare that group will be rendered inactive until issues are resolved.
