6.6.5 Storage Expansion
Without a doubt, storage plays a significant role in the field of digital surveillance, as all
recording files are saved in storage. However, users everywhere are facing the challenge of
storage capacity for long-term recording. Now, QNAP Security has introduced the storage
expansion strong feature to eliminate this problem. Making the right storage decision with
regard to storage expansion is truly important to save money and time for all users. The
various QNAP Turbo NAS models are the solution that expands on the storage capacity of
the NVR to save more recording files. The storage expansion can provide up to 64TB (16bay
model) additional space per channel, totaling more than 200TB for saving all the recording
files. Integration of both QNAP devices can help users to more flexibly and efficiently save
recording files.
Key features:
1. Addressing user needs: Users can expand their storage capacity based on their needs.
2. Reducing expense: This is a cost-effective choice to expand storage.
3. Highly scalable for storage expansion in the future.
Limitations and Restrictions:
1. Currently, Storage Expansion is supported only by the VioStor Pro(+) series and QNAP
Turbo NAS x69, x79, x70 series (with firmware version v4.0.2), and they are required
to be set on the same LAN.
2. A gigabit switch is required for this application.
3. For NVR and NAS servers located on the same subnet, please always use static IP
addresses and the same subnet mask.
4. Modification on storage expansion related setting is not supported on local display.
5. The file moving process between the NVR and NAS will be completed even if it is
suddenly interrupted (for example, the destination folder is deleted) . For example, the
cache count is set to six hours. The destination is changed to none in the middle of the
processing. When this happens, the NVR will still move recording files to the NAS until
the entire process is finished.
Note:
In order to ensure that Storage Expansion can be executed during the recording process,
please be advised to estimate the limitation on network throughput for specific VioStor NVR
series.
The following is suggested limitation of the network throughput for specific NVR models:
VS-8100 Pro+/8100U-RP Pro (+)/12100U-RP Pro (+) series: 360 Mbps.
