APPENDIX A: EXPANDING VIDEO STORAGE
You can increase the video storage capacity of the NSM5200 by adding one or more DAS5200 direct attached storage (DAS). Each DAS5200 adds
up to 12.0 TB of total capacity (up to 9.08 TB of video storage). You can add up to seven DAS5200 units to expand the total capacity for each
NSM5200 up to 81 TB of total capacity (up to 72.6 TB of video storage).
NOTES:
• You do not have to shut down the NSM5200 to add a DAS5200.
• The NSM5200 has one mini-SAS connector on the rear panel; the DAS5200 has two mini-SAS connectors on the rear panel.
• A maximum of seven DAS5200s can be connected (daisy-chained) to a single NSM5200.
To connect one or more DAS5200s to an NSM5200:
NOTE: A rack setup is used in the following configuration.
1. Install the NSM5200 and the DAS5200 (one or more) into a rack system.
2. Connect a mini-SAS cable to the SAS connector on the rear panel of the NSM5200.
3. Connect the other end of the mini-SAS cable to the top SAS connector (IN) on the rear panel of the DAS5200.
4. For each additional DAS5200:
a. Connect the mini-SAS cable to the bottom SAS connector (OUT) on the rear panel of the DAS5200.
b. Connect the other end of the mini-SAS cable to the top SAS connector (IN) on the rear panel of the next DAS5200.
