聯想海神液冷服務器營收增50%,AI耗電恐慌有救了
8月15日,聯想集團公佈財年第一財季業績,主要核心數據均超預期,營收1119億人民幣,升幅達到20%;淨利潤近23億人民幣,大幅增長65%。三大業務板塊中,ISG的表現最為強勁,營收同比增長65%,其中,兩項數據值得關注,高性能計算營收同比增長30%,而海神液冷服務器營收增50%(這是公司首次披露該數據),液冷的主要應用在高性能計算的數據中心,從數據中可以看出,聯想液冷服務器正在快速被客户採用。
聯想集團稱,海神温水水冷技術彙集了材料學、流體力學、傳熱學等多學科的結晶,目前可實現100%服務器部件用水冷卻,能夠實現單機櫃高密度水冷節點支持72 個,單機櫃功率100kW以上。該技術通過整機櫃全水冷無風扇設計,使服務器散熱效率達98%,並實現90%的餘熱回收再利用,降低42%的能耗,數據中心PUE可降至1.1。同時,並行水路設計可降低CPU、GPU等設備的性能抖動,Linpack性能提升5-10%。
同時,該液體冷卻方案還可根據不同客户的業務需要,通過温水液冷+熱能回收,綜合降低和算力無關的電力消耗,實現能源的循環再利用。海神液冷技術在全球已經得到廣泛應用,在國內,上海交通大學"思源一號"高性能計算集羣計算密度達到通用算力中心的 5 倍,而所需機房面積僅為通用機房的1/10。
此前,發改委等四部門發佈的《貫徹落實碳達峯碳中和目標要求推動數據中心和5G等新型基礎設施綠色高質量發展實施方案》也提出,到2025年,國家樞紐節點PUE進一步降到1.25 以下,綠色低碳等級達到4A 級以上。
