Limit Level Calculation Method; Calculation Example For Each Level - Canon VB-C300 Administrator's Manual

Limit Level Calculation Method

The Limit Level occurs when the Storage Server fulfills the condition 1) or 2) below.
1) When the Storage Server disk space used exceeds the following value:
Maximum disk space used
2) A When free disk space falls below the following value:
(Number of Camera Servers + 1) x 32MB

Calculation Example for Each Level

Disk Drive Disk Capacity
C Drive 100GB
D Drive 200GB
The following is a table of values for each level calculated based on the examples above.
Disk Drive Low Disk Warning Level
1) 40GB x (100-10) / 100=36GB
C Drive
2) 100GB x 10 / 100=10GB
1) 200GB x (100-10) / 100=180GB
D Drive
2) 200GB x 10 / 100=20GB
"Threshold Level" can be used as a protective level to avoid
achieving "Limit Level". It is recommended that you take
Note
measures when "Low Disk Space Warning Level" event
notification is generated, such as deleting unnecessary video
files.
Storing video data above the Threshold Level increases load
over the Storage Server and may cause recording interruption.
It is strongly recommended to use the Storage Server below
the Threshold Level.
Refer to "Operation Guideline for Recording and Viewing" (➝
P. 223) for detailed of operation.
If e-mail notification for each levels are set, the system can be
configured to provide e-mail notifications when one of these
levels is reached (➝ P. 70).
The requirements of "Threshold Level" may be achieved
before the requirements of "Low Disk Space Warning Level"
are satisfied, depending on circumstances. For example, large
numbers of cameras with limited disk capacity may bring a
larger value for "(Numbers of camera +1) x 32 MB + 96 MB",
compared with the value of "Disk capacity x Low disk space
warning level/100".
