High-availability power for data centers
UPS, PDUs, N+1 or 2N redundancy, white-space low-voltage distribution and coordination with backup generators: EOS Électricité designs data center power infrastructure sized for IT criticality and expected scalability.
A data center is first and foremost an electrical infrastructure
A data center's performance rests as much on its electrical architecture as on its IT equipment. Redundancy, independent distribution paths, sized UPS, white-space PDUs, concurrent maintainability, PUE management: every decision commits availability and operating cost for years. EOS Électricité works on data center infrastructure — new or evolving — designing architectures reasoned by IT criticality level, the expected power trajectory and operational constraints.
Challenges of data center power
Redundancy
N+1, 2N or 2(N+1): the level must match the real IT criticality, without wasteful over-spend.
Concurrent maintainability
The architecture must allow work on one path without stopping the IT load.
Power trajectory
Density per rack evolves: the infrastructure must absorb these ramps without a heavy rebuild.
PUE
Electrical quality, cooling and design directly drive overall efficiency.
An architecture sized by IT criticality
We start by qualifying the expected level of availability and the projected IT power trajectory. The retained architecture — number of paths, redundancy, UPS, PDUs, generator coordination — follows from that. Every choice is reasoned and documented for operations.
Technical expertise engaged
Data center UPS
Sizing, topology (double conversion, modular), battery management and scalability.
White-space distribution
PDUs, busway, low-voltage distribution as close as possible to the racks.
Redundancy
Independent A/B paths, selectivity, coordination with automatic transfer switches.
Generator coordination
Interface with backup generators and sequencing of transfers.
Instrumentation and supervision
Metering, power quality measurements, real-time supervision.
Typical applications
- Enterprise (in-house) data centers
- Critical server rooms in facilities
- Edge and peripheral technical rooms
- IT power extensions on existing data centers
- White-space redesigns on occupied sites
