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.
