Rack Unit | 機架單位

  • 機架單位是什麼?
    機架單位簡稱「RU」或「U」,是伺服器機架的尺寸單位,由美國電子工業聯盟(EIA)所定義。「1U」相當機架上三個插孔之間的距離,等於44.45公厘(1.75英吋)的高度;標準的19吋機櫃,總共提供42U的空間,大約是190公分的高度。安裝在機架上的伺服器,大多屬於1U、2U或4U規格,挑選伺服器時要注意,如何裝滿整個機架,同時保留足夠的空間,安裝液體冷卻方案等等。

  • 為何需要?
    數據驅動的高科技時代,大部分企業擁有自屬的伺服器機房、或是在資料中心租用空間安裝伺服器。因此,如何在有限空間內容納更多運算資源,是很重要的問題,使用一致性的機架單位,IT管理者較容易理解伺服器機架還剩多少空間、伺服器產品的尺寸有多大;也有助於伺服器廠商設計通用的伺服器產品,安裝在不同種類的機架上。

  • 技嘉的特色
    技嘉科技全系列伺服器產品,包括H系列高密度伺服器G系列GPU協同運算伺服器R系列機架式伺服器S系列儲存伺服器,皆採用1U到5U尺寸的標準規格,讓IT管理者可依照伺服器機架空間,輕鬆挑選最適合的伺服器產品。除此之外,技嘉投入大量研發資源,讓更小的機殼容納更強大的運算效能;比如說,技嘉G291-281在2U尺寸的機箱內支援高達8張GPGPU卡或協同處理器,領先業界的獨特高密度設計,在市場上無出其右。

    技嘉並且提供創新性的伺服器冷卻方案,配合機架單位的標準尺寸規格,支援高密度設計。技嘉科技攜手CoolIT等知名冷卻方案廠商,提供液冷式方案協助伺服器散熱,熱交換器可以直接安裝在標準規格的伺服器機架上。

    Silicon Valley Startup Sushi Cloud Rolls Out Bare-metal Services with GIGABYTE

    The Silicon Valley startup Sushi Cloud is competing in the public cloud sector by providing “bare-metal” services that give users exclusive access to individual, standalone servers on the cloud, resulting in a triple boost to performance, versatility, and reliability. Sushi Cloud purchased GIGABYTE’s R152-Z30 Rack Servers to offer its clients the state-of-the-art performance of AMD EPYC™ CPUs; the versatility afforded by superb memory and storage capacities, in addition to OS and software ecosystem compatibility; and GIGABYTE’s proprietary high availability features (such as SCMP and dual ROM) and remote management functions (such as GIGABYTE Management Console and GIGABYTE Server Management).

    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” 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.
