嗨，大家好，我正在设计Nutanix基础架构，并且在规格规格的情况下，我正在为最佳配置而苦苦挣扎：-2个站点（相距80 km，延迟，

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

    I'd configure them as 2 seperate clusters (1 per site) today since stretch cluster support isn't yet available today and run DR between them. Then, once stretch cluster support is released (can't quote a date :P) all you'll need to do is "stretch" the nutanix clusters and merge your vSphere cluster (as well as configure DRS affinity groups, etc.)



    这样做的主要原因是出于一些原因：


    • If the inner-site link were to fail you'd lose quorum for 1 site
    • 一旦释放了strech聚类，它的简单升级和单个命令可以拉伸。如果今天将其配置为一个群集，则基本上必须从集群中“删除”一个完整的站点，然后伸展
    • 您否定并写下延迟问题，因为卡桑德拉（Cassandra and Worlites）当前需要越过网站链接
    请随时与其他任何问题联系！

    我一直在研究可用的域功能，并且得出相同的结论。它根本没有今天的网站敬畏，因此，无法很好地处理分裂的大脑场景。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下降，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（网站本地）群集的数据会发生什么？

    我不能提供太多细节，因为尚未发布。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集群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，解决方案是一个“拉伸”的RF IE：两个不同的群集。



    If you loose a complete site will the second site restrart all the VM automatically (as of today ?)



    谢谢

    \n

    \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）没有拉伸集群。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。
