Energizing IBM Spectrum Fusion HCI
Nothing happens in an IBM Spectrum Fusion HCI system without electricity. I know that this is obvious, but sometimes we forget how important it is to get the supply of electrical power correct when setting up a system. Fusion HCI is designed to be flexible when it comes to electrical power supply so that it can adapt to the local situation in countries all over the world. Fusion HCI is also designed to be resilient to power supply failures. Let's examine the components in Fusion HCI that contribute to that design. Layers of Power Resiliency Each Fusion HCI rack contains multiple power distribution units (PDUs), and every component in the rack plugs into these PDUs. In turn, each of these PDUs plugs into a power connection in the data center. You can think of these PDUs as industrial-strength power bars. Each PDU has twelve C13 receptacles into which the power cords from the rack components plug. The C13 is the most common receptacle used by servers and switches a
