Raid function

Application

NVSS software support Raid5 and Raid 6, so there is no need to insert a Raid card if you use Raid function. When your system has more than three HDDs, you can enable RAID function. But we suggest at least six HDDs with two RAID groups, because when some HDD of one RAID group gets wrong, then you need replace it with a new HDD, the RAID group will take a long time to rebuild and can't be used to record during this period.

• Raid5 can be rebuilded successfully when there is no more than one failed disk.



The way to calculate Hard Disk Size after creating the RAID5: Size=(N-1)*min(S₁, S₂, S₃...S_N)

Notice: when use a SV35 monitoring hard disk for Raid5, there will be a lower writting speed.

• Raid6 can be rebuilded successfully when there is no more than two failed disk.



The way to calculate Hard Disk Size after creating the RAID6: Size=(N-2)*min(S₁, S₂, S₃...S_N)

Features

• Create RAID Group: Select HDD to create RAID group, please select three HDD at least, advise to choose the HDD with a same capacity. Regarding creating Raid6, it will need some time to synchronize.



• Modify RAID Group: When there is a failed disk, user need to delete this disk so that rebuild Raid group.



• Rebuild RAID Group: Choose a disk to rebuild the abnormal Raid group
