APC PDU (Power Distribution Unit) is a device that helps distribute power to multiple devices from a single source. In data centers, server rooms, and network closets, where several devices are running, APC PDU can be a valuable tool in power management. By using APC PDU, you can ensure that each device gets the required power supply without overloading the circuit. APC PDUs also come in different form factors, such as horizontal (1U, 2U) and vertical (ZeroU), and can be mounted in a variety of ways, such as in a rack or on a wall. There are three main types of APC PDUs: Basic, Metered, and Switched. In this article, we will explore the features and benefits of each type of PDU, as well as best practices for their installation and management.
Types of APC PDU
Basic PDUs
Basic PDUs are the simplest type of PDU, providing basic power distribution without any monitoring or control features. They are a good choice for small data centers or remote locations where advanced power management is not necessary. Basic PDUs are affordable, easy to install, and reliable.
- Mount it in a standard rack
- Connect the power source to the PDU input
- Connect the IT equipment to the PDU output
- Turn on the PDU switch to supply power to the IT equipment
- Monitor the LED indicators to ensure the proper functioning of the PDU and IT equipment
Best Use Cases
- Small data centers with low power requirements.
- Non-critical applications.
Metered PDUs
Metered PDUs provide basic power distribution along with monitoring features that allow data center managers to track power usage and prevent overloading.
They are a good choice for medium-sized data centers or locations where accurate power monitoring is necessary. Metered PDUs provide information such as current, voltage, power, and energy consumption. This information can be used to identify areas where power usage can be reduced and to plan for future capacity needs.
- Mount it in a standard rack
- Connect the power source to the PDU input
- Connect the IT equipment to the PDU output
- Access the web interface to monitor power usage and manage the PDU remotely
- Monitor the LED indicators to ensure the proper functioning of the PDU and IT equipment
Best Use Cases
- Small to medium data centers with moderate power requirements.
- Applications with a low to moderate level of criticality.
Switched PDUs
Switched PDUs provide advanced power distribution and monitoring features, as well as remote power management capabilities. They allow data center managers to remotely turn outlets on and off, and to monitor power usage down to the individual outlet level. Switched PDUs are ideal for large data centers or locations where remote management is necessary.
How to use Switched PDU :
- Mount it in a standard rack
- Connect the power source to the PDU input
- Connect the IT equipment to the PDU output
- Access the web interface to manage power usage and receive alerts
- Monitor the LED indicators to ensure the proper functioning of the PDU and IT equipment
Best Use Cases
- Medium to large data centers with high power requirements.
- Critical applications that require high availability and uptime.
Choosing the Right PDU for Your Data Center
When selecting a PDU for your data center, there are several factors to consider, including capacity, voltage, form factor, and management capabilities. Basic, Metered, and Switched PDUs each have their own advantages and disadvantages, so it's important to choose the right type based on your specific needs and requirements.
Comparison of Basic, Metered, and Switched PDUs:
- Basic PDUs: Simple and cost-effective, ideal for small to medium-sized data centers.
- Metered PDUs: Advanced power monitoring capabilities, suitable for larger data centers and high-density racks.
- Switched PDUs: Most advanced power management capabilities, ideal for large and complex data centers.
Remote Power Management with Switched PDUs
One of the key advantages of Switched PDUs is their ability to enable remote power management, allowing data center managers to monitor and control power usage from anywhere, at any time. This can help reduce energy costs, improve power efficiency, and avoid downtime caused by power outages or equipment failures.
Steps for Remote Power Management Using Switched PDUs:
- Install and configure the PDU and software tools
- Set up user accounts and access permissions
- Monitor power usage and manage devices remotely
- Schedule power cycles and reboots as needed
In conclusion, APC PDUs are an essential component of power management in data centers and server rooms. Basic, metered, and switched PDUs offer different levels of power distribution, monitoring, and management capabilities to meet the needs of different environments.
Basic PDU provides simple power distribution and management functions for small to medium-sized IT environments, while Metered PDU offers real-time power monitoring and measurement at the outlet level. Switched PDU provides remote power management capabilities, individual outlet control, power usage thresholds, and alerts to optimize power usage and prevent downtime.
When choosing the right APC PDU for your IT environment, consider your power management needs and the features that are important to you. With proper installation and maintenance, APC PDU can help ensure reliable and efficient power distribution to your IT equipment.
