[ Recording Server ] Recording Server v1.23 randomly not recording, Recording Failed error - 20160104

[AaronChew]

Issue:
Recording Server v1.23 randomly not recording, Recording Failed error

Root Cause:
This is due to the cameras having a higher than normal bit rate as the environment is more complex. The higher bit rate in turn causes higher incoming data and the HDDs sometimes reach 100% loading. This is why in Recording Server the write speeds are 0Mbps as the HDDs are too busy to write all incoming data.

Solution:
Advised customer to split up the cameras to recording into 6 Storage Groups instead of 3. This way the loading of HDDs will be reduced and they should have enough write speed to handle the lower number of cameras. Reference chart below for camera to Storage Group allocation for Recording Server:

If there is an abnormal count of Disk Error (1000s), users can scan HDDs for errors using HD Tune (http://www.hdtune.com/) to determine if they need to replace their HDD.
