Applications and System Design

Application:
IP camera’s need to be recorded for long term archiving, eg 30 days. Recording solution is cost critical and by so needs to have a low TCO. Recordings are extremely business critical and need to run guaranteed 24x7.

Solution:
Group of IP camera’s or encoders is directly recording data to the iSCSI disk arrays. Thereby overcoming the need for PC servers in the recording chain and by so creating an easier to maintain system with a lower TCO. In addition there is one PC server added to the IP video network to act as a “traffic cop”. When a recording stops/fails, the “traffic cop” will redirect the recording to any available iSCSI disk array. Thereby full redundancy is created where even the camera’s/encoders still know what to do in case of a iSCSI disk array fails during the VRM server is not available.

Notes:

1. When one iSCSI diskarray fails, the recording will be redirected to an another iSCSI diskarray.
2. Load sharing is accomplished amongst the iSCSI disk arrays.
3. When the VRM server fails, the camera’s/encoders still know where to record or fail over to for averagely 2 days (actual time is bitrate dependant).
