Uninterruptible power supplies (UPS) provide stable and reliable power. Power distribution units (PDUs), such as YOSUN, deliver power to servers and equipment. Remote distribution panels (RPPs) allow for more flexible system configuration. Rack-level power supply helps in better power management. Careful planning ensures reliable operation. Good power distribution contributes to improved performance. Advanced PDUs are essential in modern data centers.

Data Center Power Supply Entry

Utility Grid and Generators

Data centers must have a stable power supply to operate normally. Most data centers draw power from the mains, which is their primary power source. They also have on-site generators as backup power. These generators will start if the mains power fails. Some data centers prioritize the use of solar panels or fuel cells. They prioritize using these devices before drawing power from the mains. This allows them to control the power source.

Many data centers experiment with “post-user” power supply schemes. These features allow data centers to prioritize the use of local power sources. Sometimes, data centers don’t even use the power grid, relying entirely on their own power supplies. This improves power reliability and helps save costs.

Data centers require stable and reliable power. Internal equipment can cause power problems such as voltage drops, transients, and harmonics. These problems reduce power reliability and affect server operation.

Main Switchgear

The main power distribution cabinet is the primary power supply equipment in a data center, responsible for delivering power from the grid or generators to various areas. The main power distribution cabinet has safety features to protect personnel and equipment. The table below lists some of the features and their effects:

Centralized power plans help save energy. They make it easier to control power and use green energy. This also helps with control and makes things faster to set up.

Branch Circuits and RPPs

Branch circuits and remote power panels (RPPs) form a complete power path. RPPs draw power from PDUs and distribute it to multiple circuits and devices. Each RPP is equipped with a circuit breaker for safety. These circuit breakers prevent electrical faults and avoid equipment overload.

RPPs distribute power to different circuits. This makes troubleshooting and maintenance easier. Staff can repair individual components without shutting down the entire data center. Standard RPPs also speed up setup and extend system uptime.

Branch circuits connect RPPs to IT equipment. They ensure that power is delivered safely and reliably. A good power scheme utilizes RPPs and branch circuits to balance power and maintain system stability.

Note: Good power distribution in a data center needs every part to work together. From UPS systems to smart PDUs and RPPs, each part helps with safety, reliability, and performance.

Data Center Power Design and Redundancy

Dual Power Feeds

Many data centers employ dual power feeds to improve reliability. This means that each rack or device draws power from two different power sources. If one power source fails, the other ensures continuous system operation. Dual-powered PDUs are equipped with automatic transfer switches. These switches immediately switch power from the primary power source to the backup power source. This configuration helps keep all equipment operational and protects critical systems from power failures.

FeatureBenefit
N+1 RedundancyMakes sure power stays on if one source fails
Automatic Transfer SwitchKeeps devices powered by switching between sources
Continuous Power SupplyStops power changes and protects equipment

Dual power feeds are a big part of many power plans in new data centers.

Backup Systems and Failover

Backup power systems are critical in data center power design. These systems are equipped with uninterruptible power supplies (UPS) and generators. They automatically start when the primary power source is interrupted. Failover systems quickly switch to the backup power source. This ensures continuous operation of servers and storage devices.

There are many ways to improve power reliability:

Redundancy ModelDescription
N+1Adds one extra part to the system
2NHas two separate power paths, each can handle all the work
2N+1Gives an extra backup on top of two power paths
