Power infrastructure is an area that tests the credibility of any data centre claiming to be enterprise grade. At MCR2, the approach is built on diversity, redundancy and depth.
The facility is served by a private 11kV ring feeding into fully rated power streams and house transformers, providing a robust and independent upstream supply. From there, N+1 block redundant power streams ensure that no single point of failure in the distribution architecture can compromise service delivery.
Standby generation is provided by dedicated 2.5 MVA generators, housed within acoustic enclosures fitted with integrated fire protection. To ensure those generators are ready when needed, 72 hours of onsite fuel storage is maintained (complete with integrated fuel polishing that keeps fuel in optimum condition at all times).
Bridging the gap between mains supply and generator takeover, N+1 1.2 MW double conversion high efficiency UPS systems provide five minutes of full load backup. These systems use VRLA batteries, a considered choice that carries a significantly lower risk profile than lithium alternatives. Each power stream benefits from its own segregated electrical plant and battery room, further reducing interdependency.
At the rack level, clients receive active A and B UPS-backed power feeds providing genuine dual-feed resilience at the point of consumption.
