The data centre includes an enterprise level UPS and diesel based generator power solution. It has an auto changeover panel which automatically and seamlessly switches the power source from the mains to the generator in the event of a power failure and then back to mains supply once stable power is restored.
Bypass panels are also included which means that each element can be isolated from the system for replacement or repair without interrupting supply. Power to the data centre is an independent dedicated feed.
The power for each 42u racks in the datacentre is provided by two 16A 'commando' sockets mounted above. Each rack 'footprint' is individually fed directly from the pod's distribution board and protected by a dedicated 16A MCB circuit-breaker. This ensures that in the unlikely event of an electrical fault in one of the racks, the fault is isolated and prevents other major 'upstream' breakers tripping and causing unnecessary disruption to other server racks. Within each rack are 2 x 16Amps Power A+B Dual Feed to APC Power Bars with Remote Power Reboots.
A full 'dark' test of the power system is performed once per month in order to verify all systems are operating correctly. This test involves simulating a full mains failure, by cutting the main incoming power supply.
We are so confident in the stability and reliability of our power system that most colocation contracts include a 100% SLA, which provides a financial credit back to the customer in the unlikely of any power issues in the datacentre.
A long run fuel tank is also installed giving at least 48 hours on a single tank. In addition we have a fuel supplier on 24/7 call out ensuring that we can run indefinitely if needed.
