Workflow (Restore via XML File)
1. An external system (which can generate XML files for restoring clips, for
example MediaXChange or IPDirector) sends an XML file to XTAccess to
request the restore (copy) of clips from an archiving or backup system to a
given XT server.
2. XT Access processes the XML file:
a. It gets the clip file to restore from the external system.
b. It restores, i.e. copies, the clip on the XT server specified in the XML file.
Workflow (Restore via Folder Scan)
1. Based on the parameters defined in XTAccess, this application scans specific
folders on external backup or archiving systems.
2. When a clip file has been completed written to the scanned folder, XTAccess
creates a copy of the clip on the XT server specified in the XTAccess
parameters.
The restored clip receives a new UmID and LSM ID:
o Multicam automatically assigns a UmID to the restored clip.
o A start LSM ID is specified in XTAccess and incremented as defined for each
new clip that is restored in order to find an empty location on the XT server.
The restored clip contains the clip metadata.
3. The restored clip is moved from the scanned folder to one of the following
subfolders on the external archiving or backup system:
o \Restore.done\: folder where the files are moved to when they are
successfully restored.
o \Restore.error\: folder where files are moved to when they failed to restore.
2.9.4 SWITCHES
SUPPORTED SWITCHES
All switches used on the GbE networks of EVS systems need to support jumbo
frames (Ethernet frames with more than 1,500 bytes of payload).
Three models of 19-inch Gigabit switches have been validated for use with EVS’
workflows:
• HP Procurve 2510G-24
• Cisco Catalyst 2960G-24TC
• Cisco Catalyst 3750E-24TD/3750E-48TD
