Using InSync
Introducing InSync
Regardless of how reliable any broadcast device is, for mission-critical applications like
broadcast, many facilities require full redundancy in their play-to-air servers. Disk mirroring,
normally the responsibility of the controlling application, can add significantly to the
complexity of the application. With InSync, mirroring is accomplished within the Profile
system. InSync ensures that the contents of two systems are maintained as a mirrored pair. In
the event of a failure the user routes control of replay function to the backup system, which
InSync keeps synchronized with the main.
InSync can also provide bi-directional mirroring between two Profile systems. In this mode
InSync runs on both systems, allowing each system to operate as a main system while serving
as backup to the other.
Profile System requirements
• Supported on these Profile systems:
Not supported on PDR 100.
• Backup system must be configured to have the same number and type of active channels
(channels used for record and play) as the main system.
• Fibre Channel or Ethernet video network installed and configured. For information about
configuring a network, see the Profile User Manual for the PDR family or the
Profile XP System Guide.
• InSync must be installed on the main Profile unit. If you use bi-directional mirroring,
InSync must be installed on both Profile units.
• PortServer must be running on the backup Profile unit. If you use bi-directional mirroring,
PortServer must be running on both the main and backup Profile units. For information
about starting or checking PortServer, see the Profile User Manual for the PDR family or
the Profile XP System Guide.
NOTE: Grass Valley Group recommends that the storage capacity of the main
and backup Profile units be the same. If the capacity of the backup unit is
smaller, you must carefully manage the backup of material to avoid exceeding
the storage capacity of the backup Profile unit. Exceeding the capacity of the
backup Profile unit can result in the loss of backup material.
