大家好，我正在设计Nutanix基础架构，并且考虑到规格规格，我正在为最佳配置而苦苦挣扎：-2个站点（相距80公里，延迟，

\nThe main reason for doing this is for a few reasons:

    \n
  • If the inner-site link were to fail you'd lose quorum for 1 site \n
  • Once strech clustering is released its a simple upgrade and single command to stretch. If it was configured as a single cluster today you'd essentially have to \"remove\" one full site from the cluster and then stretch \n
  • You negate and write latency issues as cassandra and writes would need to currently cross the site link<\/ul>Feel free to reach out with any other questions!

    我今天将它们配置为2个单独的群集（每个站点1个），因为今天尚未提供拉伸群集支持，并在它们之间运行DR。然后，一旦释放了拉伸群集支持（不能引用日期：p）您需要做的就是“拉伸” nutanix簇并合并您的vSphere群集（以及配置Drs Affinity组等）

    这样做的主要原因是有几个原因：
    • 如果内部站点链接失败，您将失去1个站点的Quorum
    • 一旦释放了strech聚类，其简单的升级和单个命令即可扩展。如果今天将其配置为单个群集，则基本上必须从集群中“删除”一个完整的站点，然后拉伸
    • 您否定并写下延迟问题，因为Cassandra和Worl Work需要当前越过网站链接
    随时与其他任何问题联系！

    我一直在研究可用域功能，并且得出相同的结论。今天根本没有网站敬畏，因此无法很好地处理分裂的脑场景。如果我在一个站点上有两个街区，第二个站点上有第三个街区，则群集将在第一个站点失败的情况下降低，因为那里只是一个幸存的节点。在分裂的大脑场景中，只有第一个站点可以生存。该如何工作，以及这两个（站点本地）群集的数据会发生什么？

    我不能提供太多细节，因为什么都没发布。但是，我可以说它们仍然可以作为两个不同的簇“拉伸” - >提示：想想远程RF :)

    如果您想进一步讨论，请给我发送电子邮件

    Hint: think remote RF :)

    那很聪明！这将使您可以重新使用群集设计允许拉伸的任何地方。很想对此进行简要介绍，以优化我目前的该功能！

    你好，

    截至今天，是否支持Metro群集（拉伸群集）？

    我知道，根据此胎面，解决方案是“拉伸”的RF IE：两个不同的群集。

    如果您失去了一个完整的站点，则第二个站点将自动限制所有VM（截至今天？）？

    谢谢

    JD

    \nAs of today is the Metro Cluster (Stretched Cluster) with VMware is supported ?
    \n
    \nI understand that as per this tread the solution is a \"stretched\" RF ie: two distinct cluster.
    \n
    \nIf you loose a complete site will the second site restrart all the VM automatically (as of today ?)
    \n
    \nThx

    Nutanix 4.0.1.1（最新版本）没有拉伸群集。它可以作为v4.1的一部分发布。由于我不为nutanix工作，所以我无法提供任何进一步的信息。
