PUE

  • What is PUE?
    PUE (Power Usage Effectiveness) is the ratio of the total amount of energy used by a computer data center facility to the energy delivered to computing equipment. An ideal PUE ratio would be 1.0: 100% of the energy delivered to the data center is used for computing. However, data centers require cooling systems, lighting and other overhead that will also consume some of this energy. As such, a PUE ratio for a conventional data center will always be greater than 1.0.

  • Why you need it? Who needs it?
    In a large data center, operational expenses (such as power bills) can often be enormous and even a greater burden than the initial cost of building the data center and buying the physical equipment itself. To reduce expenses therefore, companies will strive to reduce both the energy consumption of the physical server equipment itself as well as the consumption of energy required to house and cool this equipment.

    Traditional cooling infrastructure such as air conditioning systems use a lot of energy. Therefore companies are looking to reduce the PUE of their data centers in many different ways – such as using closed loop liquid cooling systems (instead of fan cooling) on the servers themselves, which are more efficient at cooling the server and therefore allow the servers to be operated at higher ambient temperatures (requiring less or no additional air conditioning), or even using liquid immersion cooling where the entire server rack is immersed in a non-conductive fluid for cooling.

    Other companies can reduce their PUE by locating their data center in a colder climate – such as northern Europe, Russia or Alaska, requiring less additional energy to reach a lower ambient temperature, and Microsoft is even experimenting with locating data centers under the ocean.

  • How is GIGABYTE helpful?
    GIGABYTE has formed close partnerships with vendors of both closed loop liquid cooling systems (such as CoolIT and Asetek) as well as immersion cooling systems (such as LiquidStack and Submer) to offer a variety of different solutions to help customers reduce their PUE. Partnering with these companies allows GIGABYTE to offer our servers that have been modified, tested and validated to work with these different solutions to provide for quick and easy deployment.

    Japanese Telco Leader KDDI Invents Immersion Cooling Small Data Center with GIGABYTE

    Japanese telco giant KDDI Corporation has invented a new class of data centers that are mobile and eco-friendly. These “container-type immersion cooling small data centers” will employ “single-phase immersion cooling” to reduce power consumption by 43% and lower the PUE below 1.07. GIGABYTE Technology drew from its years of experience in the telco sector to provide the R282-Z93 and R182-Z91 Rack Servers for KDDI to use as the management and GPU computing nodes in the data center. KDDI benefits from the servers’ powerful 3rd Gen AMD EPYC™ CPUs, the scalable, high-density configuration of NVIDIA® GPUs in small form factors, and the servers’ optimized compatibility with the liquid-based data center cooling solution. GIGABYTE’s participation in KDDI’s project is in line with GIGABYTE’s long-term CSR and ESG efforts, which are focused on working with global industry leaders to “Upgrade Your Life” with high tech while building a greener, more sustainable environment for our future.

    Semiconductor Giant Selects GIGABYTE’s Two-Phase Immersion Cooling Solution

    GIGABYTE Technology has built a “two-phase immersion cooling solution” for one of Taiwan’s foremost semiconductor giants, to be used in its sustainable, future-proof “green HPC data centers”. Not only does the solution boost the performance of HPC processors by over 10%—which is crucial for the nanometer process technology used in IC foundries—it also reduces data center power consumption by 30% and lowers PUE below 1.08, which turns it into a role model of green computing that may be replicated in data centers around the world. This exemplary project demonstrates how GIGABYTE can support its clients’ CSR, ESG, and SDGs-related initiatives, and how GIGABYTE is working tirelessly to “Upgrade Your Life” with high tech while protecting our environment.

    What is Private Cloud, and is it Right for You?

    In the era of cloud computing, just about everyone has heard of the terms “private cloud” and “public cloud”. Chances are, you are using one or both of them in your everyday life—but how much do you really know about them? If you had the chance, could you build a private cloud for yourself or your organization? GIGABYTE Technology, an industry leader in server solutions used by global cloud service providers, is pleased to present our latest Tech Guide. We will examine the difference between private and public clouds, introduce the private cloud’s advantages and limitations, and then introduce GIGABYTE products that may help you build and operate a private cloud of your own.
