Manage recorder hard drives

Perform disk management to defragment hard drives, identify hard drives that are to be monitored, and apply threshold settings to those drives as there is always a limited amount of disk space for recordings.

Threshold settings

Use the Recorder Manager to set the hard drive threshold settings by specifying one or more drives to host the call buffer and the size of the threshold. This threshold determines when calls will be automatically deleted to make room for newer recordings. Disk Manager always deletes the oldest call first and then advises you by generating a log file.

Calls buffer

When the Recorder records calls, it stores them on the disk in the Calls Buffer. Since the Calls Buffer is used repeatedly it is possible that over time the disk might become fragmented.

Better disk performance

The task of defragmenting disks is minimized because disk cluster sizes have been increased to 64 kilobytes to reduce the need to defragment. One issue resulting from larger block sizes is that it means using a 64K disk cluster for the 1-2k .xml file used for each call’s metadata. If you have a .wav file that takes up say 10 blocks (that is, 640k @ 3k/s=3.5 minute call) and one block is used for the .xml file it means that you are potentially using 10% of your disk space on a the small .xml files. However this is a trade-off for better disk performance.
