[Low disk space warning level] Calculation Method
The [Low disk space warning 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:
M x (100 - A)/100
M: Value for [Maximum disk space used]
A: Value for [Low disk space warning level]
Example: In case of the value for [Maximum disk space used] is 100 GB and the value for [Low disk space
warning level] is 10%, the Storage Server reaches the [Low disk space warning level] when the remaining
free disk space becomes 10 GB or less.
2. When free disk space falls below the following value:
Disk capacity x A/100
A: Value for [Low disk space warning level]
Example: In case of the value for disk capacity is 80 GB and the value for [Low disk space warning level] is
10%, the Storage Server reaches the [Low disk space warning level] when the remaining free disk space
becomes 8 GB or less.
Threshold Level Calculation Method
The Threshold 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:
a. When [Maximum disk space used] is set 384 MB or more,
[Maximum disk space used] - 96MB
b. When [Maximum disk space used] is set 384 MB or less,
[Maximum disk space used] x 3/4
2. When free disk space falls below the following value:
(Number of Camera Servers + 1) x 32MB + 96MB
Tip
If other applications are also using the same hard disk, you need to review the condition 2). Even if the
Storage Server uses a small quantity of disk space, it may reach the [Low disk space warning level]
because other applications has consumed disk space.
