About RAID5 Storage
RAID storage is a system which allows hard drives to be linked together to form a single
large capacity storage device that offers superior performance, storage capacity, and
reliability over other storage solutions.
The VNM Recorder uses RAID5 storage. RAID5 storage provides the following advantages.

Transport Protocols Used for Streaming
The source data from a VN-Matrix encoder can be distributed to multiple displays/decoders
(one-to-many) or to a single display/decoder (point-to-point). A previously recorded stream
can be distributed in the same way and may be thought of as an encoder in this context.
A stream may be transported from the source (encoder, recorded stream) to the display
(decoder) using one of three methods:
•
•
•
By default, the VNM Recorder provides a choice of unicast RTP or unicast TCP transport
protocols. A multicast transport protocol may be configured if required (see
Enable
NOTES:
Increased storage performance.
Full data redundancy which allows for data backup in the event of a hard drive failure.
A hard drive is set aside as a hot spare drive which is used to automatically rebuild the
data of a failed drive and allow the system to recover.

•
During playback of a recorded stream, the default transport protocol used is unicast
RTP.
•
When a stream is recording, the VNM Recorder may be considered as a display
(decoder) device.
