Data volume to reach 175 zettabytes in 2025
Data Centers Must Maximize Energy Efficiency for Sustainability

With the volume of data expected to increase exponentially through various digital applications such as video streaming, virtual conferencing, cloud services, and cryptocurrencies, Infineon Technologies (hereinafter Infineon) is taking the lead in data center decarbonization.

Infineon Technologies (hereinafter Infineon) announced on the 27th that it is supporting data center decarbonization by providing power stage semiconductors to Supermicro Computer.

Following the U.S. International Trade Commission (ITC)'s forecast that the volume of data will reach 175 zettabytes as early as 2025, industry experts predicted that the amount of data will increase 146-fold within 15 years.

Currently, about 8,000 data centers are still processing, storing, and networking massive amounts of data.

For data centers, not only are performance and security important, but maximizing energy efficiency is also crucial for profitability and sustainability.

Amidst this, Supermicro Computer (hereinafter Supermicro) adopted Infineon's high-efficiency power stage semiconductors.

Manhtien Phan, Supermicro’s Vice President of Server Technology, said &ldqu“When developing the green computing platform, we selected vendors capable of lowering power consumption through improved energy efficiency,” he said. “By using Supermicro’s solutions and Infineon’s technology to reduce system power consumption, we will decrease the overall power usage of data centers and lower our environmental impact.”

Adam White, President of Infineon’s Power and Sensor Systems division, stated, “Data center cooling accounts for a significant portion of energy consumption. Infineon’s TDA21490 and TDA21535 power stage products are designed to reduce heat dissipation in data centers.” “These semiconductors can withstand high temperatures and offer excellent reliability, enabling free air cooling for servers. This further improves the power usage efficiency of data centers, thereby increasing energy efficiency,” he said.

The Power Usage Efficiency (PUE) index is calculated by dividing the total power supplied to the data center by the power actually consumed by IT equipment, and the ideal PUE value is 1.0.

In a recent survey, IT and data center managers reported that the average annual PUE in their large-scale data centers reached 1.57, indicating room for improvement in unmanaged cooling and power costs and a reduction in the CO2 footprint.

Supermicro's green computing platform provides maximum server density with various processors and can significantly improve PUE.

With free air cooling and BBP® (Battery Backup Power), installation and provisioning are easy thanks to data center-friendly features and design.

In particular, MicroBlade achieves 86 percent improved power efficiency and 56 percent improved density compared to a standard 1U rackmount server.

The MicroBlade server adopted Infineon's OptiMOS™ IPS (integrated power stage) TDA21490 and TDA21535.

The TDA21490 is a high-performance xPU, ASIC, and SoC used in server, memory, AI, and networking applications that enables robust and reliable voltage regulator designs.

This device achieves maximum efficiency with an OptiMOS power MOSFET in a thermal efficiency package. Deep sleep mode is enabled with a driver that has low quiescent current, further improving efficiency under light load and enhancing system performance through excellent current monitoring.

The TDA21535 integrates a synchronous buck-gate driver IC with low quiescent current and high-side and low-side MOSFETs into a single package, and with an active diode structure, the body diode forward voltage (Vsd) is as low as that of a Schottky barrier diode.

The internal MOSFET current measurement algorithm and temperature compensation function achieve superior current measurement accuracy compared to the highest-level controller-based inductive DC resistance measurement techniques.

It operates at a maximum switching frequency of 1.5 MHz to achieve a transient response with excellent performance and allows for lowering output inductance and capacitance while maintaining the previous efficiency.

Meanwhile, Supermicro Computer is an innovative company leading high-performance, high-efficiency server technology that provides advanced server building block solutions for embedded systems such as data centers, cloud computing, and enterprise IT.
