Intelligent Rack PDUs for AI Data Centers | High-Density Power & Monitoring

AI server racks demand a significant amount of power, necessitating a stable and reliable power supply 24/7. Any fluctuations or disturbances in the power feed to these high-value assets can have a serious effect on their ability to support advanced computing workloads. Therefore, ensuring that your intelligent rack PDU (Power Distribution Unit) meets these demands is a critical consideration for data center operators.

Where once a rack PDU was considered a basic power strip to power 10-20 kW per rack, in the era of AI, high-capacity intelligent PDUs are essential for managing and monitoring rack densities that increasingly exceed 70-100 kW per rack. High-density data centers, hyperscalers, and colocation facilities not only require PDUs with high-density designs, but also advanced power management, metering, and monitoring capabilities. These features help prevent circuit overloads, safeguard equipment, and optimize energy efficiency.

So, what functionalities should operators consider when selecting a high-density rack PDU for their AI and HPC infrastructure?

High-Density Power and Outlets

In response to growing power demands, operators should choose high-density PDUs capable of supporting higher power loads. Additionally, the form factor is critical to ensure these PDUs fit seamlessly into densely packed rack environments while accommodating increasing power requirements.

For example, INOWA’s Metered or Switched PDUs feature with IEC Lock CX combination outlets (C13/C15/C19/C21) outlets. This design allows flexible connection of C14, C16, C20 and C22 power cables to be installed in a single flexible outlet, maximizing the number of outlets in a single PDU and the physical rack space available to support compute-intensive applications.

These advanced rack PDU solutions are designed to meet even the most demanding power needs with customizable options including form factor, breaker count, outlet type, and more:

• Voltages from 208V to 400V AC
• Input current from 16A to 125A
• Power Capacity of 10 kW to 90 kW+
• Form factor options from vertical 0U and horizontal 1U to 3U
• Up to 12 20A 10kAIC hydraulic-magnetic circuit breakers

Advanced Power Monitoring & Management

Many data center managers are oblivious to the design of their power system nor have real-time visibility into system state or performance. Without this information, response to critical alarms is delayed which can lead to unplanned downtime. In addition, enforcing availability and redundancy requirements during capacity planning activities proves to be difficult and time-consuming without detailed knowledge of the system. To prevent downtime before it escalates, Innowave Power offers a comprehensive set of intelligent features, including real-time visibility, reporting, and alerting of power metrics and events. Key features include:

• Integrated ±1% energy metering accuracy
• Advanced power quality monitoring, covering A (Aggregate Current), V (Voltage), W (Active Power), kWh (Power Consumption) and power factor at both the PDU’s inlet and outlets
• Metering at the Rack PDU Circuit Branch inclining circuit breaker status monitoring
• Plug-and-play rack management accessories

By analyzing the collected data, technicians can identify power quality issues at the rack level and determine their causes. This insight enables data center operators to create effective power quality mitigation plans that align optimization strategies with sustainability goals.

Environmental and Security Monitoring

With increasing AI workloads, data centers experience higher power consumption and heat generation, which can impact cooling efficiency and operational costs. To optimize cooling and prevent energy waste, it’s essential that rack PDUs can monitor environmental factors like temperature, humidity, and etc.

The INOWA PDUs offer a wide range of rack-based, plug-and-play solutions for managing critical IT devices effectively. These include:

• Environmental and security sensors
• Electronic smart door locks

By using sensors to monitor these conditions, data centers can protect equipment from damage and enhance security by detecting misuse or suspicious activities.

Cybersecurity

Today’s rack PDUs are designed as intelligent, networked devices. However, this connectivity also introduces new cybersecurity risks, and many legacy PDUs still lack essential protections and remain at risk.

Innowave Power has integrated advanced cybersecurity features into its intelligent rack PDUs,  including:

• Secure Boot: This feature ensures that only verified firmware runs on your PDU, preventing tampering and malicious code execution.
• Encrypted Communications: All devices utilize AES 128b/256b encryption, along with firewall support and robust password policies.
• ETSI EN 303 645 Compliance: The PDUs meet or exceed the requirements of leading security regulations for IoT devices.

As AI adoption continues to grow, INOWA’s industry-leading, high-density PDUs will help data centers manage the transition to significantly higher capacities, providing the flexibility and intelligence required to support evolving power infrastructures.
