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 completely written to the scanned folder, XTAccess
creates a copy of the clip on the XS 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 XS 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.
2.8.4 SWITCHES
SUPPORTED SWITCHES
All switches used on the GigE 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
COMPARISON
The HP Procurve 2510G-24 and Cisco Catalyst 2960G-24TC can be used for small
setups where no inter-VLAN routing is needed.
On larger setups, both Ethernet ports of the XS servers or/and several ports on
the XF[2] are often used to increase the bandwidth or to allow redundancy. Since
both Ethernet ports of an XS server cannot be used on the same sub-network,
virtual LANs need to be created. To allow the transfer of packets between the
virtual LANs, layer 3 switches are required. You need to select a layer 3 switch
that is able to route jumbo frames.
A switch of the Cisco Catalyst 3750E series should be used on larger setups as
they support jumbo frames, allow traffic to be routed between different VLANs and
provide stacking capabilities.
The following table gives an overview on the supported switches:
