The common challenges of using paper diagrams include:ĭifficult to share, review, and provide feedback on In a data center, a single-line diagram is typically printed on paper and hung on a wall somewhere. DC bays that divide and distribute individual loads from the DC power plant to equipment downstream.DC power plants that provide uninterrupted DC power.Floor power distribution units (PDUs) that transform raw power feeds into lower capacity feeds that feed into remote power panels or busways and rack PDUs.Uninterruptible power supply (UPS) units that provide emergency power during an outage until the power returns or a longer-term backup system turns on.Automatic transfer switches (ATS) that switch to a backup power source when there is an outage.Switchboards that divide and distribute power into branch circuits.Switchgears that control, protects, and isolates electrical equipment.Transformers that convert electrical power from one voltage or current to another voltage or current.Generators and fuel tanks that deliver backup power during an outage.The equipment that a data center typically tracks with a single-line diagram includes: The vertical orientation of these diagrams also enables data center managers to easily see redundant power paths side-by-side. This simplifies planning, troubleshooting, and maintenance to help maintain uptime and increase efficiency. In data centers, single-line diagrams are used to visualize the complete power path. How Do Data Centers Use Single-Line Diagrams? The top of the diagram marks the beginning of the flow of electricity and the nodes at the top typically represent power sources such as the utility feed, generator, or battery.Īs you progress down the single-line diagram, you can follow the flow of power to other equipment downstream. Nodes are arranged vertically from top to bottom. The electrical components, or nodes, in these diagrams are represented by standardized schematic symbols. What is Data Center Service Management (DCSM)?Ī single-line diagram (also known as an SLD or one-line diagram) is a drawing that charts out the electrical sources, components, and connections in a power distribution system.What is the Federal Data Center Optimization Initiative (DCOI)?.
