Disk Space Management (Important) The Storage Server monitors the disk space and responds according to the amount of available space. Disk Space Status Explanation Notification level indicating that the remaining disk space is low 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 Limit level The Storage Server calculates a reference value based on various conditions and settings. 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. Value for [Maximum Disk Space Used] Notification level 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 remaining free disk space becomes 10 GB or less. 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 Drive Disk Space Free Disk Space Value for [Maximum Disk Space Used] Value for Low Remaining Disk Space Notification Level D Drive 100 GB 50 GB 40 GB Condition 1: 40 GB x (100-10)/ 100 = 36 GB Condition 2: 100 GB x 10/100 = 10 GB E Drive 200 GB 200 GB 200 GB Condition 1: 200 GB x (100-10)/ 100 = 180 GB Condition 2: 200 GB x 10/100 = 20 GB 7-4
