Data center operators need 24×7 visibility to critical electrical data. Let’s consider some concrete examples. a. Granular electrical data: Data from power and energy meters help answer operational questions such as “How much load is that circuit carrying? Do I risk tripping if I add more server load? Is that transformer overloaded?” Timely access to such data can help optimize electrical capacity, so you “sweat” your assets but avoid compromising your redundancy. Figure 3.
