6.12 Storage Manager

Find the Storage Manager in the Global data – Storage manager menu. This menu helps you define all storages necessary for the PBX operation and services. In addition to classical internal storages (such as DATA, NAND), you can map network disks and MMC cards, which make the usable space almost unlimited and provide access to such services as call recording, for example.

Logical Storages

Logical storages represent the basic storing units for all PBX services and functions. You can add logical storages to the PBX from a pre-defined set but cannot create logic storages of your own. Logical storages themselves have no reserved data space. Hence, you have to map one physical storage at least to each logical storage, such as the internal memory, MMC card or network disk (CIFS – Common Internet File S.).

Right-hand button context menu actions:

• Expand all – unfold the logical storage tree into a view of the physical storages.
• Collapse all – fold the tree structure into a view of the logical storages.
• Add logic storage – select and add a pre-defined logical storage.
• Add physical storage – add a physical storage to the currently selected logical storage. You can only add physical storages as created in the Physical storages section.
• Remove – remove the selected physical storage or logical storage including all of its physical storages.
• Remove all – remove all logical and thus all physical storages from this section.
• Default – reset the current structure of logical/physical storages to the default values. All the physical storages added are ignored and remain in the structure.

Properties

• Strategy – select how to choose physical storages for the given logical storage. A linear strategy is only available at present. The selection is active when you click on any of the logical storages. You can change priority of the physical storages by Drag&Drop function. 
  
  • Linear – data are stored in a sequence starting from the first physical storage. When the first storage is full, the next physical storage in the sequence is used.
• Move register of files to storage – move a register of records and VoiceMail messages to a storage in a separate file instead of the PBX database. If, however, Shift files is selected too for the given physical storage, the register will remain in the PBX database. Files (records and VoiceMail messages) are always moved to a storage with the highest priority or the first available storage without the Shift files selection located above the storage from which the files are to be moved.

• Keep files removed from register – delete the removed files from the register but keep them in the physical storage.
• Delete empty directories – when the file validity expires, the respective directory will be automatically deleted too.
• Mapping – the section is active when you click on any of the physical storages and includes the following parameters.
  
  • Status – this parameter displays the current status of the selected physical storage within a specific logical storage, including whether the storage is available or full.
  • Read only – this parameter disables file editing for the given physical storage. The files can be read only.

  • Shift files – set the given physical storage as temporary. The files stored here are not archived but shifted to a storage with a higher priority. If this option is enabled, the Move register of files to storage parameter cannot be applied for the selected storage. For example, in the event of network storage failure, files are stored in the next storage in the sequence and the file register is stored in the PBX database. When the network storage becomes available again, the files and file registers are moved to it.

    Caution

    • All database records created before version 4.1.x are deleted when the Shift files option is selected. If the Move register of files to storage parameter is disabled, files are deleted from the storage too.
  • Path – this parameter defines the path to a directory within the logical storage mapped. This accelerates physical storage mapping as you just search the selected directory instead of the entire structure. Make sure that the selected directory really exists in the specified location.
  • Usable space – the parameter specifies some space in the currently selected physical storage to be occupied by the given logical storage. It is because one physical storage may be used by multiple logical storages (by defining the used directory, e.g.), each of which may be assigned a different data space size. Set -1 to leave the space unlimited on this level.
  • Used – this non-editable parameter informs of the current occupation of the space reserved for the selected physical storage. 

Quotas

Table columns:

• Subject type – this column displays the subject type to which the row relates. Choose User, Group, Virtual port, or Virtual port type.
• Subject – defines a subject of the above selected type.
• Usage quota – defines the usable space for the given subject within the logical storage data space (for all its physical storages).
• Item size – defines the maximum file size for the given subject.
• Number of items – defines the maximum count of files to be stored for the given subject within the logical storage data space.
• Item life [s] – sets the time for which the file stored for the given subject shall be kept in the logical storage data space.
• Delete oldest achieving quota – enables deletion of the oldest user files within the logical storage data space (when the file retaining time expires). 

List of files

If you are on the logical storage level, you can see all files contained in the corresponding physical storages. If you select a physical storage, you can only see the files saved in the particular physical storage.

Right-hand button context menu actions:

• Re-read view – you can refresh the current file list within the logical storage data space.
• Remove – use this option to remove the selected file.
• Rename – use this option to rename the selected file.
• Create directory – use this option to create a directory within the data space of the currently used physical storage.
• Import file – add a file from a PC to the currently used physical storage.
• Export file – load a file from the logical storage data space into a PC.

Table columns:

• Name – file name.
• Size – file size.
