Disk Space Management <Important>
Limit Level Calculation Method
The Limit Level occurs when the Storage Server satisfies 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 S 1) x 32MB
Calculation Example for Each Level
The following is a table of values for each level calculated based on the above examples.
Disk Drive
Disk Capacity
Free Disk Space
Max. Disk Space Used
Camera Server No.
C Drive
100GB
50GB
40GB
19 units
D Drive
200GB

Threshold Level
Limit Level
C Drive
1) 40GB x (100-10) / 100=
36GB
2) 100GB x 10 / 100=
10GB
1) 40GB-96MB=
39.904GB
2) (19+1) x 32MB+96MB=
736MB
1)
40GB
2) (19+1) x 32MB=
640MB
D Drive
1) 200GB x (100-10) / 100=
180GB
2) 200GB x 10 / 100=
20GB
1) 200GB-96MB=
199.904GB
2) (19+1) x 32MB+96MB=
736MB
1)
200GB
2) (19+1) x 32MB=
640MB
“Threshold Level” can be used as a protective level so that the
“Limit Level” is not achieved. It is recommended that you take
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. 208) for details of operation.
For each of the levels, the system can be configured to
provide e-mail notifications when one of these levels is
reached (
➝
P. 64).
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 1) x 32 MB + 96 MB”,
compared with the value of “Disk capacity x Low disk space
warning level/100”.
