Redundancy is a best practice when you are looking at how a data center is powered. In order to maximize uptime and mitigate failures, look into “N + 1” power – this means that each component has an available and independent back up. While data centers that maintain redundancy in machinery can be common, True A + B power (where two separate lines/power environments are delivered to each cabinet) is much rarer.
Even more rare is the ability to measure and pay for consumption-based usage. Redundant power especially can become expensive to install and supply. Consider how able your data center is to monitor and bill you for exactly what you use.
ACI is able to offer True A + B power and redundant connections to a second data center that features redundant power as well. We even go so far as to deliver two independent, scalable power supplies to each cabinet with the ability to monitor and charge for exact usage each month.
