在AI时代提升基础设施效率以满足日益增长的需求

As demand for AI continues to grow, so does the infrastructure needed to support it. Much of the industry's attention has focused on building more: more data centers, more servers, and more power. But building new infrastructure is only part of the challenge. Engineering teams are also working within constraints on energy, cooling, hardware availability, and physical space, making it increasingly important to get more from the infrastructure that's already in place.

随着对 AI 需求的持续增长，支持它所需的基础设施也在不断增加。业界的大部分注意力都集中在建设更多设施上：更多的数据中心、更多的服务器和更多的电力。但建设新基础设施只是挑战的一部分。工程团队还必须在能源、冷却、硬件可用性和物理空间等限制条件下工作，这使得从现有基础设施中获取更多价值变得日益重要。

For over a decade, Dropbox’s Infrastructure and Datacenter Engineering teams have continually improved how we plan, operate, and optimize infrastructure. That work spans far more than storage systems. Engineers across Dropbox work together on capacity planning, fleet optimization, hardware lifecycle management, power delivery, cooling, rack design, and facility planning. Rather than treating these as independent problems, we optimize them as parts of a single system, where decisions in one layer influence what's possible in another.

十多年来，Dropbox 的基础设施和数据中心工程团队不断改进我们规划、运营和优化基础设施的方式。这项工作远不止存储系统。Dropbox 的工程师们在容量规划、集群优化、硬件生命周期管理、电力分配、冷却、机架设计和设施规划等方面协同工作。我们没有将这些视为独立的问题，而是将它们作为单一系统的一部分进行优化，其中一层的决策会影响另一层的可能性。

The result is an engineering discipline that extends beyond any single system or optimization. A change in one part of the infrastructure can create opportunities or constraints elsewhere. Increasing storage density, for example, can reduce the amount of hardware needed, while more powerful servers can introduce new energy and cooling requirements. Understanding those tradeoffs allows us to make infrastructure decisions with the entire system in mind.

其结果是一种超越任何单一系统或优化的工程学科。基础设施某一部分的改变可能会在其他地方创造机会或带来限制。例如，增加存储密度可以减少所需的硬件数量，而更强大的服务器可能会带来新的能源和冷却需求。了解这些权衡使我们能够以整个系统为考量来做出基础设施决策。

As infrastructure demand grows, that system-level approach helps us prioritize efficiency and create room for growth before expanding...
