The Storage Server monitors the disk space and responds
according to the amount of available space.
„
Action When the Low Remaining Disk Space
Notification Level is Reached
The Storage Server issues an event when the disk space
available for recording (i.e. available space relative to the
maximum disk space used) goes below a certain level.
If [Maximum Disk Space Used] is not set, the drive
capacity of the disk that stores the recording file is
considered to be the maximum disk space.
Note
On receiving an event e-mail notification, an administrator can
act promptly (for example, by removing unnecessary recording
schedules) before a problem occurs due to low disk space.
Low Remaining Disk Space Notification Level
Conditions and Calculation Method
If one of the following conditions is met, a low remaining
disk space notification level is indicated.
Condition 1: If the Storage Server disk space usage
exceeds the following values:
M x (100 - A)/100
(M: Value specified in [Maximum Disk Space
Used], A: Value specified in [Low Disk Space
Warning Level])
For example, if 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 remaining disk space notification
level when the Storage Server disk space usage
becomes 90 GB or more.
Condition 2: If the free disk space falls below the
following values:
Disk space x A/100
(A: Value specified in [Low Disk Space Warning
Level])
For example, if the disk space is 80 GB and the
value for [Low Disk Space Warning Level] is 10%,
the Storage Server reaches the low remaining disk
space notification level when the remaining free
disk space becomes 8 GB or less.
Note
If other applications use the same hard disk, you need to
consider condition 2. Even if the Storage Server uses a small
amount of disk space, it may reach the low remaining disk space
notification level according to condition 2 because other
applications have consumed a portion of the disk space.
Calculation Example

Disk S pace S tatus Explanation
Low remaining disk space
notification level You can specify a reference
value using [Low Disk Space
Warning Level] on the
[Recording Settings] tab in
the [Storage Server Group
Settings] dialog box.
Threshold level The Storage Server calculates
a reference value based on
various conditions and
settings.
Limit level
Important
An event e-mail notification is sent when the priority level of
[Low Disk Space Warning] in the [Events] tab of the [Storage
Server Group Settings] dialog box meets or exceeds the level
specified in the e-mail notification settings. (p. 42).
