Main electrical panel
Our main electrical panel is duplicated with an 'A' side and 'B' side so every server has two completely independent power feeds for redundancy.
HV transformers & generators
Above our transformers and generators a gantry carries our busduct - this leads the power from the transformers and generators back into the building.
Multiple SDMO 1.1MVA generators for emergency power are tested monthly & configured in an N+1 set up. In the unlikely event the mains power fails, the entire data centre load is supported.
Our 'A' side room of UPS batteries is duplicated on the 'B' side. The batteries support power to servers if there is a transient or disturbance on the mains load or during time taken for generators to start.
The UPS filter on our 400kVA UPS units cleans the power through an inverter/rectifier and isolation transformer so the power supplied to the servers is stable and reliable.
