CDU for High-Density Data Center Cooling
Over the past decade, air cooling has remained the dominant thermal management method in data centers. However, the rapid growth of AI training, high-performance computing (HPC), and accelerated workloads is pushing rack-level heat density beyond what traditional air systems can efficiently handle in certain deployments. As a result, liquid cooling is increasingly applied in high-density zones—such as [...]
What Is a Server Rack?
A server rack is a standardized metal framework used to mount servers, networking equipment, storage devices, and supporting hardware such as power distribution units (PDUs). Most server racks follow the 19-inch width standard, which ensures compatibility across equipment from different manufacturers. Rather than stacking devices randomly on shelves or floors, racks allow equipment to be securely mounted [...]
3 Types of UPS: Understanding Uninterruptible Power Supply Systems
An Uninterruptible Power Supply (UPS) plays a critical role in protecting IT equipment from power disturbances. From brief voltage dips to full power outages, even a short interruption can cause data loss, hardware damage, or service downtime. The level of protection a UPS provides depends largely on its internal design. In general, UPS systems are classified into [...]
What Is Data Center Infrastructure Management (DCIM)?
Data Center Infrastructure Management (DCIM) is a software framework designed to centrally manage a data center’s physical infrastructure. It brings together information that was traditionally scattered across separate systems and documents—such as asset inventories, power, cooling, environmental conditions, and space capacity—into a single platform. This unified view gives operators a visual, measurable, and predictive understanding of how [...]
Data Center Cooling Systems — Types, Advantages, and Comparisons
As data centers continue to support cloud computing, AI workloads, and edge applications, cooling is no longer just a background utility—it has become a defining factor in reliability, efficiency, and long-term operating cost. Modern facilities rarely rely on a single “best” cooling method. Instead, operators choose from multiple cooling system types based on rack density, site conditions, [...]
Top 10 Precision Air Conditioning Manufacturers for Data Centers in 2025
Precision air conditioning is essential for modern data center cooling and other mission-critical environments. As power density increases, choosing the right precision air conditioning manufacturer has become a key factor in ensuring reliability, energy efficiency, and scalable data center operations. The following list highlights ten leading precision air conditioning manufacturers in 2025, based on their experience in data center precision [...]
4 Types of PDU in Data Centers: Overview and Features
In a data center, power availability is only the starting point. As facilities grow in size and complexity, operators need to understand where power is being consumed, how it is distributed, and whether the infrastructure can safely support future expansion. This is where Power Distribution Units (PDUs) play a critical role.Modern PDUs are no longer simple power strips. They have become [...]
Immersion Cooling for Data Center : Advantages and deployment
For more than a decade, air cooling has been the “default answer” for data centers. It is mature, reliable, well understood, and has supported large-scale growth from traditional enterprise IT to early cloud computing. However, as computing paradigms evolve—higher-power chips, more centralized workloads, and denser deployment models—cooling has gradually shifted from a supporting system to a design [...]
How PDUs, CDUs, and PUE Shape Data Center Efficiency
Why Data Center Efficiency Is No Longer Just About Power When data center efficiency is discussed, many people still instinctively think in terms of “how much power is consumed” or “what the PUE looks like.” But in real-world data center operations, efficiency has never been a single-point issue. While servers consume electricity, they also continuously generate heat. [...]
Direct-to-Chip Liquid Cooling : How It Works and Application
As AI, HPC, and high-density computing workloads become the norm in data centers, cooling is no longer a “supporting system,” but a core piece of infrastructure that directly affects compute performance, energy efficiency, and long-term operational costs. Against this backdrop, Direct-to-Chip (D2C) liquid cooling is moving from niche deployments to large-scale adoption and has become one of [...]
