设想：

2个服务器室，相距1公里，直接纤维连接。

每个服务器室中的一个10节点/机架。

最有意义的是什么？

1.使用同步代表创建两个群集。

2.创建一个具有机架容错的群集（每个服务器房间中一个机架）

Scenario:<\/p>\t

2 server rooms 1km apart with direct fiber connection.<\/p>\t

One 10 node\/rack in each server room.<\/p>\t

\u00a0<\/p>\t

What would make most sense?<\/p>\t

1. Create two clusters with sync rep.<\/p>\t

2. Create one cluster with rack fault tolerance (one rack in each server room)<\/p>\t

\u00a0<\/p>\t

Hello\u00a0<\/p>

1-Rack fault domain needs minimum 3 rack not 2 for RF2.<\/p>

2-Sync Replication makes more sense depend on your RPO objectives<\/p>

3-Check the below link for Sync Replication requirements:<\/p>

    不确定您的实际业务需求在上升时间是什么，但是解决方案1总体上更好。2.如果在侧面下降时2/3节点，也不会从网站故障中产生产品。由于我们如何处理元数据，因此在跨站点上有一些技术设计问题。

    Not sure what your actual bussiness requirments are for up time but solution 1 is better overall. 2. Also wouldn\u2019t product from a site failure if 2\/3 nodes when down on a side. There are some techincal design issues with rack awarness across sites due to how we handle the metadata.<\/p>","quoteUsername":"dlink7","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    你好

    1型故障域需要至少3个机架，而不是2个机架。

    2-sync复制更有意义，取决于您的RPO目标

    3-检查以下链接以获得同步复制要求：
