问HN：数据中心升级时，所有硬件会发生什么？
似乎每隔几年就会有大量硬件被淘汰，因为新的、更强大的系统不断问世。<p>AWS发布了一段视频和一篇文章，介绍了它如何回收大量硬件，因为这些硬件在设计时考虑到了可维护性和可修复性。<p>这有多真实？这是否适用于其他数据中心运营商？<p>即将升级的所有并行计算卡会怎样处理？它们不能被重新利用作为游戏玩家的GPU，对吧？

It seems like there will be a lot of hardware that gets discarded every couple of years as new, more powerful systems are made available.<p>AWS put out a video and article on how it recycles a large amount of its hardware, since it is built for maintainability and repairability.<p>How true is that? Does it apply to other datacenter operators as well?<p>What will happen to all the parallel compute cards that will get upgraded soon? They can't be reused as GPU's for gamers, can they?
