大型数据中心的电力消耗高达兆瓦级，设备成本高达数亿美元，因此减少服务器的能源消耗和成本将产生重大影响。Web、网格和云服务器尤其难以优化，因为它们需要在各种工作负载下运行。对于我们即将推出的数据中心，我们着手显著提高其电源效率、成本、可靠性、可维护性和环境足迹。为此，我们重新设计了数据中心和服务器的许多维度。本文重点介绍了我们的新服务器设计，结合了电源、主板、散热和机械设计等方面。我们通过实验计算并确认，我们定制设计的服务器可以在整个负载范围内降低功耗，同时降低获取和维护成本。重要的是，我们的设计不会降低服务器的性能或可移植性，否则会限制其适用性。
Large-scale data centers consume megawatts in power and cost hundreds of millions of dollars to equip. Reducing the energy and cost footprint of servers can therefore have substantial impact. Web, Grid, and cloud servers in particular can be hard to optimize, since they are expected to operate under a wide range of workloads. For our upcoming data center, we set out to significantly improve its power efficiency, cost, reliability, serviceability, and environmental footprint. To this end, we redesigned many dimensions of the data center and servers in conjunction. This paper focuses on our new server design, combining aspects of power, motherboard, thermal, and mechanical design. We calculate and confirm experimentally that our custom-designed servers can reduce power consumption across the entire load spectrum while at the same time lower acquisition and maintenance costs. Importantly, our design does not reduce the servers' performance or portability, which would otherwise limit its applicability.
