Nx Witness provides a simple way to manage storage in a System. Each Media Server can use unlimited local and network storage. If more than one storage location is used the Nx Witness Media Server will automatically balance space consumption across drives. Usage intensity is strictly related to storage availability.
To Configure/Modify Local HDDs:
- Right click on a Server in the Resource Panel and choose Server Settings.
- Make sure any storage locations you'd like to use are checked.
Nx Witness will automatically reserve space on every drive assigned for storage according to the following basic rules:
System Drives (e.g. C: drive)
A system drives contains the operating system. As such, Nx Witness tries to avoid using this drive if at all possible.
- Disabled for recording unless it is the only drive and/or it is at least 10 times smaller than any other drive on the computer.
Local Hard Drives / HDDs (e.g. D: drive)
Any drive which is to be used exclusively for archived video.
- Reserved space will be will not exceed more than 10% of any individual drive's capacity.
- See below to see how to modify HDD reserved space.
NAS devices are treated as one large hard drive and recordings are streamed from an Nx Server to the NAS device over a network connection (LAN, WAN)
- Reserved space will be 50-100GB and will not exceed more than 10% of the NAS's capacity.
- See Add NAS Devices article for details.
ARM Devices (e.g. Nx1, Raspberry Pi)
ARM devices typically have smaller storage drives (e.g. 32GB SD Card) with low capacity.
- Reserved space will be 1GB on SD Cards.
To modify reserved space on HDDs:
- Navigate to http://serverIPaddress:7001/static/index.html#/advanced
- Log in with your Owner or Admin credentials.
