Increased Bandwidth: Data Centers Need to Make Energy-Saving Changes – Huawei

The rapid evolution of computing power and bandwidth requires that data centers, most of which consume a lot of electricity, must start to evolve and make changes to save energy and reduce emissions. to avoid contributing to climate change concerns, tech company Huawei said.

“Today, the need for computing power extends to every corner of the digital economy, from smart banking to smart retail and from smart manufacturing to smart logistics. In the blink of an eye, the world has realized that robust computing power is essential in all aspects of our daily lives.Meanwhile, smarter and greener data centers are being built at an accelerating rate.

“As the demand for data centers grows and the scale of data center construction increases, energy conservation becomes an increasingly pressing challenge,” the company said in a statement.

According to the China Academy of Information and Communications Technology (CAICT), by the end of 2021, Chinese data centers had a combined total of more than five million standard rack units (U). To put this into context, an ultra-large data center with more than 10,000U consumes 100 million kWh of electricity every year, and the annual electricity consumption of data centers worldwide exceeds 200 billion kWh. All of this means that transforming data centers, with a focus on making them greener and low-carbon, should be a priority.

Power utilization efficiency (PUE) – the ratio of the total power consumption of data center devices to the power consumption of information technology (IT) devices – is a key indicator to measure the energy consumption of data centers. A lower PUE rating means a more efficient data center. In order to reduce PUE, a common industry practice is to use more renewable resources while continuously improving infrastructure technologies, such as cooling and power distribution, to minimize energy consumption.

“As data center computing power and network bandwidth continue to increase, so does their energy consumption. However, the significant increase in energy consumption cannot be fully compensated by the simple use of renewable resources. To save more energy and reduce data center emissions, we need to think outside the box. Specifically, we need to improve computing capacity and reduce energy consumption per unit of computing power to get the most out of every kilowatt-hour of electricity.

“This is part of the reason the Huawei CloudFabric 3.0 hyperconverged DCN is designed. The solution navigates green computing with higher quality networks

“Using lossless Ethernet networks, Huawei’s CloudFabric 3.0 Hyper-Converged Data Center Network (DCN) solution enhances network capabilities to maximize computing efficiency, while minimizing power consumption per unit of computing power. , enabling green data center networks with optimal computing power”. said.

Based on the iLossless 2.0 algorithm, Huawei’s CloudFabric 3.0 hyperconverged DCN solution implements the industry’s first Ethernet with zero packet loss. In this way, it builds a large-scale, low-latency, high-throughput computing power network, unleashing 100% of the computing power. For example, in a High Performance Computing (HPC) scenario, Lossless Ethernet provides 17% higher compute efficiency than an InfiniBand (IB) network, reducing overall compute time.

CloudEngine data center switches use more than 10 industry-leading heat dissipation and power technologies, such as SuperCooling and SuperPower, delivering 54% lower power consumption per bit than the industry average and lower power consumption. 47% less energy per unit computing power than traditional Ethernet.

And finally, based on the principle of “no use, use less and reuse”, Huawei CloudEngine data center switches enable sustainable low-carbon manufacturing. For example, to achieve a green and manufacturable design, Huawei integrated the independent packaging of optical modules into a six-in-one package, reducing unpacking time by 85% and saving 18 tons of packaging materials.

“Huawei CloudEngine series data center switches are designed to improve energy efficiency and reduce noise pollution, while adhering to green manufacturing practices. Going forward, Huawei will continue to innovate to help equip enterprise data centers with high computing power to accelerate their green transformation, giving momentum to the campaign for global carbon neutrality,” says the press release.
