Disk Management architecture

Disk Management architecture is designed around the premise that there is
always a limited amount of disk space for recordings. This means that when
insufficient disk space is detected, the oldest call is deleted and/or moved to
another media.
The Recorder uses a circular disk buffer to implement a policy that allows
the Nortel TDM Recorder to continuously record without the hard disk
filling up. This is accomplished by using a component called the Disk
Manager, as shown in the following diagram:
