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

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

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。

嗨,到目前为止,是否支持Metro群集(拉伸群集)?我知道,根据此脚步,解决方案是“拉伸” RF IE:两个不同的群集。如果您放松一个完整的站点,则第二个站点将是第二个站点的约束力所有VM自动(截至今天?)THXJD
