Appendix E: External Storage Expansion Using DX9200HDDI
BASIC INSTALLATION
The DX9200HDDI can increase the DX8000’s storage capacity by up to 3.2 TB. The external IDE RAID is connected to the DX8000’s optional SCSI
interface by a 50-pin to 68-pin SCSI cable, included with the DX9200HDDI. The DX9200HDDI option is available for DX8008-080 and DX8016-080
systems that are preconfigured at the factory.
1. Connect either one or two DX8000 DVRs to a single DX9200HDDI with a standard 50-pin to 68-pin SCSI cable.

*The test case used in evaluating the DX8000’s ability to operate in real-time with the DX9200HHDI storage array was conducted using a
16-channel DVR recording at 24 ips and 320 x 240 resolution.
IMPORTANT:
• The DX9200HDDI can be used for either offline backup storage or real-time video storage. When used as a real-time storage device,
the frame rates of each channel on the DX8000 must be set at less than or equal to 24 images per second (ips) for 16-channel DVRs
and up to 30 ips for 8-channel DVRs. Setting the frame rate above 24 ips for a 16-channel DVR will result in skipped frames and
significant performance degradation.*
• To connect the DX9200HDDI to the DX8000, the optional DX8000-ISCI internal SCSI interface must be installed.
• Make sure HDDI power is turned on first and then turn power on to the DX8000.
