DATA CENTRE STRATEGY
“Operational safety is not a secondary consideration; it is a prerequisite for long-term uptime”
Michel Bommer, UPS Technology Director – R & D, Legrand
Instead of focusing on capacity, component redundancy, or compact designs, Michel says that“ resilience must be assessed by how systems perform under stress, during maintenance, and failure scenarios”.
“ It is also essential to evaluate how effectively they preserve service continuity throughout the UPS lifecycle,” he adds.
Reliability must be engineered and proven For operators of mission-critical facilities, service continuity is not an incidental outcome. Instead, it is inherently engineered into operations.
Modular UPS systems designed for high-density environments distribute intelligence, power and redundancy across every essential subsystem – a strategy Michel describes as“ highly effective at eliminating single points of failure”.
“ By duplicating each critical component, these architectures guarantee power delivery, even in the event of a component’ s fault or during active maintenance,” he explains.“ The ability to contain faults, no matter where they occur, without disrupting the load, is critical to maintaining service continuity in highavailability environments.”
Modern UPS designs embed redundancy at every critical level to maximise availability and fault tolerance. Key architectural elements include:
• Parallel, hot-swappable power modules that allow instantaneous load sharing and automatic compensation if a module fails, maintaining output performance without interruption.
• Dual, independent communication buses that ensure real-time synchronisation between modules and supervisory controls, safeguarding against disruption if one communication channel is compromised.
