Configuring Server and NAS Storage

DW Spectrum provides easy and flexible storage management controls. Each servercan use an unlimited number of local and network storagepaths. If more than one storage locationis used, the Media Serverwillautomatically balance consumption so free space is distributed between available resources.

Each local hard disk partition is considered a storage location. 

IMPORTANT: 10-30 GB of free space is always preserved on each storage location. For NAS storage, this amount may vary between 50 and 100 Gb depending on the storage size. If only one system partition (where OS is installed) is present, then DW Spectrum will use this partition for recording. If any other disk is added and an extended partition is created, then the system partition will be disabled for recording and DW Spectrum will record data to the extended partition(s).

 NOTE: USB storage is not a supported option.

To configure server storage

1. Open the server's context menu and go to Server Settings -> Storage Managementtab.

2. DW Spectrum discovers and displays local storage resources.

In the example shown below, the computer has 3 partitions. Disk E is the main storage partition and disk D is configured as backup. Disk C is not used because it is a system partition (where the operating system is installed) and there are two other storage locations in the list. The system disk drive is only used if it is the only storage location on a server and it is at least five times smaller than any other drive on the server.

3. Click on a storage location and use the button at the end of the row to toggle it on or off. There must always be at least one Main storage location. Once a main storage location is enabled, any other storage location can be set to Main or Backup as needed.

Note: At least one drive must be set to Backup for archive backup to be possible.

4.DW Spectrum will check all storage locations for validity and confirm the ability to write to each. If a drive is not available or has insufficient space, a warning will display.

5. To configure backup storage, see "Configuring Backup and Redundant Storage".

Note: Because some cameras record directly to their own internal storage, DW Spectrum must periodically download archive from the camera's internal storage to DW Spectrum System servers. See "Remote Archive Synchronization ".

To add external storage

IMPORTANT: Make sure NAS is available, and accessible through the network on which the computer server is installed.

1. Open the server's context menu and go to Server Settings -> Storage Managementtab.

2. Click Add External Storage

3. Choose the desired option from the Protocolmenu,and enter the storage path (URL), Login, and Password for the external storage device.

4. Click OK to accept the entries and add the new device to the list of storage locations.

5. Set the button at the end of the row to set as Backup or Main.

To find archive on a storage device

The storagestructure on a partition is as follows:

<drive>/DW Spectrum Media/$Resolution/$ID/$YYYY/$MM/$DD/$HH



hi_quality – full resolution streams

lo_quality – low resolution streams

$ID – if reported, the MAC address of the recorded device, otherwise the Camera ID

$YYYY – year recorded

$MM – month recorded

$DD – day recorded

$HH – hour recorded
