Fault Tolerance Comparison Why ETERE fault tolerance is better than Harris

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

Harris Air protect Main output Rs422 Rs422 Clone output

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

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

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

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

Etere Gives You More

ETERE Cloning Main output Active Redundant Ethernet connections Active Clone output

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

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

Fault Resilience An example

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

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.

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.

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.

After 2 hours Back on 100% main Clone

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

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