Advanced properties for storage arrays

Advanced properties for storage arrays provide information about the low disk space thresholds and buffered reads and writes.

See Editing default options for a virtual disk on a storage array.

Item

Description

First threshold

Displays the first low disk space threshold at which you want Backup Exec to send an alert. You can change the value of the threshold, and you can change the amount of disk space to megabytes or gigabytes.

When the amount of used disk space reaches this threshold, Backup Exec sends an alert. The default threshold is 75%, which is a percentage of the total available disk space on this virtual disk.

 

Second threshold

Displays the second low disk space threshold at which you want Backup Exec to send an alert. You can change the value of the threshold, and you can change the amount of disk space to megabytes or gigabytes.

When the amount of used disk space reaches this threshold, Backup Exec sends an alert. The default threshold is 85%, which is a percentage of the total available disk space on this virtual disk.

Third threshold

Displays the third low disk space threshold at which you want Backup Exec to send an alert. You can change the value of the threshold, and you can change the amount of disk space to megabytes or gigabytes.

When the amount of used disk space reaches this threshold, Backup Exec sends an alert. The default threshold is 95%, which is a percentage of the total available disk space on this virtual disk.

Auto detect settings

Indicates if Backup Exec automatically detects the preferred settings for this device.

Uncheck Auto detect settings if you want to set buffered reads or writes.

The default setting is On.

Buffered read

Indicates the following:

  • You do not want Backup Exec to automatically detect settings for this device.

  • You want this device to allow buffered reads, which is the reading of large blocks of data.

If you enable buffered read, increased performance may result.

The default setting is Off.

Buffered write

Indicates the following:

  • You do not want Backup Exec to automatically detect settings for this device.

  • You want this device to allow buffered writes, which is the writing of large blocks of data.

The default setting is On.
