A Power Distribution Unit (PDU) is an essential device used in a data center to distribute electrical power. It is responsible for evenly distributing AC power to multiple servers and other equipment. PDUs are of various types and can be as basic as a 120-volt power strip or as advanced as a remotely manageable unit with SNMP protocol management capability.
Types of PDUs
- Basic PDUs
- Metered PDUs
- Smart PDUs
- Switched PDUs
- Rack-mount PDUs
- Vertical PDUs
- Maintenance bypass PDUs
Features of an Advanced PDU
An advanced PDU is a remotely manageable unit with SNMP protocol management capability. This enables outlets to be turned on and off at predetermined times and in proper order for equipment shut down and startup. Other features of an advanced PDU include power monitoring capability, environmental monitoring, and ability to trigger alarms or alerts in case of power surges or load imbalances.
FAQ
What is the importance of having a PDU?
A PDU plays a significant role in the proper distribution of power supply in data centers, ensuring that power is evenly distributed among different IT equipment. It’s critical to maintain a proper power supply as it directly affects the uptime and the lifespan of servers and other equipment.
What is an advanced PDU?
An advanced PDU is a remotely manageable unit with SNMP protocol management capability. This enables outlets to be turned on and off at predetermined times and in proper order for equipment shut down and start-up.
What is the difference between a basic and an advanced PDU?
A basic PDU is a simple 120-volt power strip, while an advanced PDU is a remotely manageable unit with SNMP protocol management capability, power monitoring capability, environmental monitoring, and ability to trigger alarms or alerts in case of power surges or load imbalances.
Conclusion
A PDU is a crucial component of data centers, it’s important to choose the right type based on the needs and requirements of the IT infrastructure.
