PDU socket strips
Server rooms are the heart of modern information technology infrastructures.
The computing resources found in these server rooms allow us the activity of the social networks,
Worldwide business and personal interactions and every "entity" that is present in the network.
At the center of the infrastructure in these rooms are socket strips, known as PDU (Power Distribution Units),
In this article I will review the importance of socket strips, their different types, selection considerations, installation, maintenance and security.

The importance of socket strips (PDU) in server rooms:
Outlet strips (PDU) are the central connection point between the power source and the equipment in the server room.
They enable efficient distribution of electricity, load management, and PDU power consumption monitoring.
high-quality guarantee a stable and continuous power supply, which prevents interruptions in the operation of the servers and related equipment.
Different types of socket strips:
1. Basic socket strips: provide a simple electrical connection without additional features.
2. Managed socket strips (Managed PDU): include remote monitoring and management capabilities.
3. Smart & Switched PDU strips: offer advanced features such as monitoring and performing a RESET at the individual outlet level.
As can be seen in the following picture (strip of sockets in a stick configuration also called 0U):
4. Socket strips with voltage protection: protect the equipment from voltage jumps and electrical surges.
5. Configuration: PDU will usually come in a stick configuration, called OU, since this configuration does not occupy a lateral space (U), but is installed on the sides of the cabinet.
A second horizontal configuration, like a pizza tray, and houses 1U, 2U, 3U and sometimes even more, depending on the number of sockets.
Considerations in choosing socket strips
Electrical capacity: the capacity must be adjusted to the needs of the equipment in the server room.
The number of sockets and their configuration: it is important to ensure enough sockets and appropriate connection types.
Management and monitoring capabilities: choosing "smart" PDUs enables advanced control and management.
Compliance with standards: Compliance with relevant safety and quality standards must be verified.
Installation and maintenance
Correct installation of the PDU (socket bar) is essential to ensure safety and efficiency.
Proper wiring, proper grounding, and orderly cable management must be observed (the subject of an article in its own right).
Regular maintenance includes periodic tests of the connections, cleaning, software update in the case of "smart" socket strips.
Advantages and disadvantages of different socket strips
Basic PDUs are simple and easy to install,
Their cost is relatively low and they are used exclusively to transfer voltage to the units connected to them.
It is not possible to manage them.
Managed and "smart" outlet strips offer many advantages in managing and controlling and monitoring their activity,
Their cost is higher than the basic lines, they require more advanced technical knowledge to operate.
Securing the socket strips against hacker penetration
With the advancement of technology, the "smart" socket strips that are permanently connected to the network have become a potential target for cyber attacks.
Hackers may exploit security weaknesses to disrupt power supplies or steal sensitive information.
The UL2900 security standard makes it possible to raise the security level of all equipment connected to the socket strips that meet this standard.
It should be taken into account that the studies in the field indicate an unimaginable number of 31 billion products that will be connected to the network by the end of 2025.
Below are a number of measures to protect the socket strips:
Security Updates: Ensure that the PDU's firmware and software are always up to date.
Encryption: use of strong encryption protocols for communication between the PDU and management systems.
Two-step authentication: Setting up strong authentication mechanisms to access the management interface.
Network Segmentation: Isolating the PDU in a separate network from the general corporate network.
Continuous monitoring: implementing systems to identify and prevent dedicated intrusions into socket strips.

Future trends in PDUs for server rooms
The future brings with it many innovations in the field of outlet strips (PDU).
The integration of artificial intelligence is expected for smarter management of electricity consumption, which will allow dynamic load prediction and regulation.
IoT (INTERNET OF THINGS) technologies will be integrated for advanced monitoring and preventive maintenance.
Advances in green energy are also expected, with PDUs directly supporting renewable energy sources.
In addition, developments in cyber security will offer improved protection against advanced threats.
Future socket strips will also be more modular,
Allow for easier adaptation and expansion to the changing needs of modern server rooms.
In conclusion,
PDUs are a critical component in server rooms, directly affecting system performance and reliability.
Correct selection, professional installation, regular maintenance and strict PDU security are key to ensuring proper and continuous operation of the server room.
With the development of technology and cyber threats, it is important to treat the socket strips not only as a means of supplying electricity,
but also as an end point in the corporate network that requires special protection and attention.
Future trends promise further improvements in PDU efficiency, security and flexibility, which will contribute to an overall improvement in server room performance.
