RAID C
ONFIGURATION
DVN 5000 Series models can be configured for RAID 0 or RAID 5. Although RAID 0
provides 25% more storage space than RAID 5, when a hard disk drive fails in a RAID 0
configuration, data loss occurs (see the following caution statement).
Now that hard disk drives have a much greater storage capacity at a better cost value, a
RAID 0 configuration for the DVN 5000 has less benefit, especially when considering the
risk of data loss.
If you purchased a DVN in a RAID 0 configuration and you wish to convert the system to
RAID 5, refer to the
DVN 5000 Rackmount Series RAID Management Guide
for detailed
instructions.
Enabling RAID Critical Alarms
Johnson Controls recommends enabling the
Broken raid disks detected
and
Broken or missing disk for raid 1 detected
alarms so that you are notified and can
take corrective action in the event the RAID status changes to critical.
!
CAUTION
Loss of Data.
A single hard disk drive failure in a DVN 5000 RAID video array
configured for RAID 0 will result in a
total loss of data
in the entire array. To
assist in avoiding this for a single drive failure, convert the DVN 5000 RAID
configuration from RAID 0 to RAID 5, which uses parity to provide a fault tolerant
solution. In a RAID 5 configuration, a defective drive can be identified and
hot-swapped, with no loss of data or disruption to the DVN server's functions.
