Description
This guide is an overview and outline on the redundancy options available with HELIOS.
What is Redundancy?
System redundancy refers to the practice of including duplicate components or systems within a larger system to ensure reliability and availability. This provides backup in case one component fails, thereby preventing a single point of failure from disrupting the entire system's operation. Redundancy is especially important for events that can't be reproduced, or "failure is not an option", such as concerts, real-time events, or live broadcasts.
Redundancy Modes Offered by HELIOS
HELOS offers different types of redundancy, depending on how resilient the system needs to be vs. how much extra gear can be facilitated.
| RESILIENCY LEVEL | HELIOS | MODE | |
| Most resilient | Dual HELIOS | Seamless | Use video from main & backup simultaneously |
| Dual HELIOS | Failover | use backup when main is unavailable | |
| Single HELIOS | Seamless Loop | single processor redundancy | |
| Least resilient | Singe HELIOS | None | Do not expect a backup processor |
