这段时间，由于各种因素，市场确实很难做，但Memory（主要是海外）和光却都表现的不错，OFC 期间，各家公司都展示对未来乐观的预期。这篇文章我们聊一下本周讨论度非常高的XPO，解析一 下Arista XPO的White Paper，看下有哪些市场可能忽略的一些细节。 "光"话题的讨论向来是比较激烈，海外某个大V因为写了CPO进展超预期的文章，被骂的已经删除了 自己的专栏。笔者之前因为转了一篇citi对于CPO超预期看法的会议内容，也引来了很多骂声。 笔者无意参战XPO/CPO什么时候到来的讨论，下面的内容大部分都是Arista XPO的内容解析，有些 是笔者结合自己的行业调研加入的，但不包含XPO/CPO等的时间进度。 一、AI 浪潮下的基础设施困局 当 AI 数据中心的规模突破 10 万 GPU，当单个训练任务的成本攀升至数百万美元，当传统网络架构 在极限带宽需求面前捉襟见肘，我们意识到，是时候重新定义数据中心光学互连了。这个白皮书是今 年3月份，Arista Networks 联合 45+产业伙伴发布的。 白皮书开篇就直指 AI 网络面临的五个关键痛点： OSFP 的极限 说到这里，就不得不提业界现在普 ...
