Redundant systems – we have the necessary experience
Eneria has successfully implemented projects involving installing generator sets for parallel operation. Our generator sets are capable of redundant operation, depending on the plans and needs of the owner of a Data Center project. Redundant power supply solutions ensure the maximum level of machine protection in a server room if the power grid fails.
We minimize the risk of breakdown and increase safety
Our solutions enable improving the reliability of electric power supply to servers via two independent circuits. Each circuit includes a generator set and two groups of UPS. Each server rack at a data center is equipped with two power distribution units (PDU). Each of them is connected to a different power supply circuit.
Remote monitoring and control of generator sets via a high-speed network enables parallel connection of a group of generator sets equipped with a synchronization panel to a single source of the mains power supply.
REDUNDANCY – options
Power supply redundancy increases the safety of data transmission.
Possibilities that every customer has, depending on the security level they want to achieve for their Data Center, are shown below.
| CLASSIFICATION | DEFINITION | REDUNDANCY LEVEL | TIER UPTIME INSTITUTE |
| N | INDISPENSABLE LEVEL, MEETS THE MINIMUM REQUIREMENTS FOR CAPACITY | LOW

| N+1 | ONE UNIT ABOVE THE NEEDS.
THIS CAN REFER TO THE LEVEL OF A COMPONENT OR OF A SYSTEM (N+2, N+3,… FORMS ARE ALSO POSSIBLE) |
MODERATE
A BREAKDOWN OR DISCONNECTION OF SOME COMPONENTS FOR MAINTENANCE PURPOSES WILL NOT IMPACT THE CRITICAL LOAD VALUE. |
