EVS XTract Version 1.02 - July 2013 User Manual - Manual (Page 9)

3. Network Architecture
XTract is installed on the same computer as an XTAccess application. XTract is the
interface application used to manage the backup and restore functions.
The files to be archived and restored are located on one or several EVS video servers and
storage units connected to the same Ethernet network.
Two networks are used for the various communications and for the file transfers as
illustrated. Physically, these networks can be one and the same or separate for the sake
of performance:
• The PC LAN network is used to detect EVS video servers, to identify them, and to
transfer the list of clips to be backed up.
• The Gigabit Ethernet (GigE) network is used to transfer the clips data between the
XTract and XTAccess computer, the EVS video servers and the storage unit.
