1. Fault Tolerance Comparison
Why ETERE fault tolerance is better than Harris

2. Fact Louth Automation (now known as Harris) is an old design product
They added a fault tolerance option to an old architecture

3. Harris Air protect
Main output
Rs422
Rs422
Clone output

4. Harris Air protect
Harris air protect uses 2 ports of the same ADC100 controller to give to the users a ‘false impression’ of Fault tolerance
The same Device controller with the same Software and windows OS controls 2 ports of 2 servers
It protects from the server Errors but not as a Harris Error

5. Harris Cloning Switch Main output Active Rs422 Cold Stanby Rs422
Clone output

6. Harris Cloning
In this case the ‘false impression’ is also more evident
You need to have 2 ADC100 controllers
The 2nd one is on “standby”
A switch changes the 422 ports from Main to Bkp system if the Main fails
You’ll find out that there is a problem on the BKP TOO late, when it has already been sent On-air

7. Then Louth system is not able to give you any real fault tolerance
The red points show you the single failure points of the Louth system or the architecture unmanaged problems

8. Harris Cloning Switch Main output Active Rs422 Cold Stanby Rs422
Clone output

9. Etere Gives You More

10. ETERE Cloning Main output Active Redundant Ethernet connections Active
Clone output

11. ETERE Cloning
In ETERE Cloning you have 2 Active controllers which control the 2 outputs
You can check the running of both systems frame by frame
With a redundant Ethernet connection, ETERE gives you more than Fault Tolerance. It gives you Fault Resilience

12. Fault Tolerance V.s. Fault Resilience
Fault tolerance means that if one component fails you still can broadcast with the 50% of your system
Fault resilience means that if you there was a fault in one part of your system you still can broadcast with the 90% of your system
An ETERE Automation system can survive to multiple failures and give you more than the 50% of its functionality

13. Fault Resilience
An example

14. Onair Indipendence main Clone
The automation processes are indipendednt and always running.
You can be 100% sure that the clone is UP and running.
You are protected against os failures as pc failure as software failure,
The main and clone can be different as hardware

15. Etere Ingest main Clone
It’s completely independent from other system operations like Caching or manual recording.
This example shows 2 recording processes on 2 different machines.

16. One Fault and You are on 75%
What happens in a distributed environment if one of the Caching processes fails?
Nothing.
The On Air system is still running, and all the other parts of the system are still working properly.

17. After 5 minutes You are on 90%
While someone repairs the defect, the operator reconfigures the system.
This way all TV activities and all devices will still be running, but from a limited number of PCs.
You can work as usual until the defect has been repaired.

18. After 2 hours Back on 100%
main
Clone

19. 4 different Fault Tolerance Schemes
Cloning: Two outputs synchronized in frame
Backup: One “cold” backup channel
One2many : One backup channel shared among multiple active channels
Disaster recovery: A different site automatically updated from the main site and 100% independent

20. Etere Fault Tolerance
No other vendor is able to give you the best fault tolerance solution on the market today
