– Failover
Recordings are saved only to primary target. If it is not possible to save to this target, the
recording will be saved to the target entered under secondary target.
A failure situation is reached if the primary target does not provide storage blocks due to
whatever reason: system down, network error, no capacity left.
You can leave the second list empty. In this case no failover is possible but the number of
required iSCSI sessions is reduced and no disk space on secondary target is allocated.
This reduces system overhead and extends the system retention time.
– Automatic
Load balancing is configured automatically. Each encoder is automatically assigned
2 iSCSI targets and blocks on these 2 iSCSI targets are assigned to the encoder.
– Recording Preferences tab, page 34
Sanity check period (days)
Move the slider to configure the required time period. After this time period the iSCSI target is
checked and blocks are reassigned if needed.
Secondary target usage
Enable or disable the use of a secondary target.
Block reservation for downtime
Enter the number of days that the assigned encoders will be recorded although the
VRM Server is down.
For example, if you set 4, the encoders will be recorded during approximately 4 days of
VRM Server downtime.
If your system has encoders with low bit rate, you can significantly reduce the pre-allocated
disk space. This ensures a proper distribution of storage capacity and extends the retention
time.
