DESCRIPTION
The DX9200HDDI video storage unit is one of the components of the DX9000 system. The storage unit contains up to 14 IDE
hard disk drives for storing video information from the DX9000 recorder. Up to four IDE storage units can be connected to a
recorder.
The storage unit uses redundant arrays of independent disks (RAID) technology. Level 5 or Level 5+1 is available. In Level 5,
data is divided between drives in such a way that if one drive fails, the data can be reconstructed from the remaining drives.
Level 5+1 is similar to Level 5, but it includes a hot spare drive. If a drive fails, the redundant data relocates automatically to
the hot spare and begins the reconstruction process without user intervention.
Features include:
• 14 hot-swappable Ultra DMA hard drive trays
• Maximum storage capacity of over 3 terabytes
• Fault tolerant data protection
• Supports redundant arrays of independent disks (RAID) levels 5 and 5+1
• Automatic detection and disconnection of failed hard drives
• Automatic online rebuild of new hard drives
• Industry standard 19-inch (48.26 cm) wide rack-mountable chassis
WARNING: The storage unit’s configuration has been preprogrammed in the factory for either RAID 5 or RAID 5+1 based on the
order received. Do not attempt to change the unit’s configuration. Doing so can render the unit inoperable.
