Power Requirements
SnapStream servers are equipped with dual hot-swap power supplies that are both redundant, and load-balancing. A single unit may be replaced without a system power-down. They also support auto detection of 100-240V and 50-60Hz power.
Below are the server configurations and their respective power consumption statistics.

Best Practices
Minimal Configuration
Each system power supply unit plugged into an ‘uninterrupted power supply’ (UPS) or ‘battery backup unit’ (BBU.) Protection provided for single system power supply unit failure, and minor power outages or failures.
Better Configuration
Each system power supply unit plugged into a separate UPS or BBU. Protection provided for single system power supply unit failure, power outages, and single UPS/BBU failure.
Best Configuration
Each system power supply unit plugged into its own UPS/BBU, each of which is powered by separate, independent circuits. Protection provided for single system power supply unit failure, power outages, single UPS/BBU failure, and single facility circuitry failure.
UPS VA Recommendations
When deciding on UPS hardware, it is important to choose a solution with the appropriate VA rating. This rating allows you to calculate the prospective uptime of a server in the event of a power failure, based on the power draw of the system. Listed below are some approximate times for our servers based on UPS hardware with standard VA ratings*.
