It has a built-in power metering module that can record data such as current, voltage, and power in real time. These data help you analyze the power usage of your equipment and optimize energy distribution.
In contrast, the technical features of the switch PDU focus more on power control. It supports remote switching operation, allowing you to manage each socket individually through the network. The switch PDU also has a timing function to help you achieve automated power management.
Tip : If your data center requires precise power monitoring, a metered PDU is a better choice. If you are more concerned about remote control and automated management, a switched PDU is more suitable.

Different application scenarios
Metered PDUs and switched PDUs are suitable for different application scenarios. Metered PDUs are usually used in scenarios where accurate monitoring of power usage is required. For example, in an environment where energy costs are sensitive, you can discover and reduce energy waste through data analysis of metered PDUs.
Switched PDUs are more suitable for scenarios that require frequent remote operations. For example, when a device needs to be restarted, you can quickly restore the device to operation through a switched PDU without having to go to the site in person. This function is particularly important in large data centers or remote sites.

Analysis of their respective advantages and disadvantages
The following is a comparison of the advantages and disadvantages of metered PDU and switched PDU:

By comparing, you can choose the appropriate PDU type according to the needs of your data center. If you need to meet the needs of both precise monitoring and remote control, you can consider using the two PDUs together.

Application scenarios of metered PDU and switched PDU in data centers

Application of Metering PDU in Accurate Power Monitoring
In data centers, power monitoring is a key task to ensure stable operation of equipment. Metered PDUs help you fully understand the power usage of equipment by recording data such as current, voltage, and power in real time. You can use this data to analyze energy efficiency and identify potential waste problems. For example, when a server's power consumption is abnormal, a metered PDU will provide data support in a timely manner to help you quickly locate the problem device and take measures.
In addition, metered PDUs also support the generation of detailed power usage reports. These reports can help you optimize energy distribution and reduce overall operating costs. If your data center requires accurate power monitoring, metered PDUs are an indispensable tool.

Application of Switching PDU in Remote Power Management
The remote control function of the switch PDU provides great convenience for power management in the data center. Through the network, you can switch each socket anytime and anywhere. This function is especially important when the equipment needs to be restarted. For example, when a server fails, you don’t need to go to the site in person to operate it. You can just shut down and restart the equipment remotely through the switch PDU. This not only saves time, but also reduces the impact of equipment downtime on the business.
Switched PDUs also support timed switching. You can set up automated power management plans based on the operating requirements of the equipment. For example, you can shut down some equipment during off-peak hours to save energy. This flexibility makes switched PDUs an indispensable management tool for modern data centers.

The synergy of the two PDUs in hybrid deployments
In practical applications, the combination of metered PDU and switch PDU can play a greater role. Metered PDU provides accurate power monitoring data, while switch PDU provides flexible power control functions. Through hybrid deployment, you can achieve energy optimization and remote management at the same time. For example, you can use metered PDU to monitor the power consumption of equipment, and remotely shut down unnecessary equipment through switch PDU to reduce energy consumption.
This synergy is especially important in large data centers. Faced with a complex network of equipment, a single type of PDU may not meet all needs. Hybrid deployment can make up for the shortcomings of a single device and provide you with a comprehensive power management solution.
Tip : When choosing a PDU, it is important to evaluate the specific needs of your data center. Through a reasonable hybrid deployment, you can maximize the advantages of both PDUs and improve the operational efficiency of your data center.
