查询异步复制条件

我们有2个带有ESXI管理程序的Nutanix簇。我们正在使用Metro的可用性来在群集之间复制DataStores \容器。我们想复制某些位于这些地铁中的容器中的VM，以转到潜在的第三站点。我们正在考虑为此使用异步复制。

这可能是可能的吗？

我之所以这样做，是因为在“实施异步复制的条件”指南中，有一种条件指出“多个保护域不能保护相同的VM。配置一个保护域以保护VM”。

We have 2 Nutanix clusters running with the\u00a0ESXi Hypervisor. We\u2019re using Metro availability to replicate datastores\\containers between clusters. We\u2019d like to replicate some of the VMs that reside in these Metro enabled containers over to a potential 3rd site.\u00a0 We were thinking to use Async replication for this.<\/p>

Is this possible and is it supported?<\/p>

I ask this because in the \u201cConditions For implementing Asynchronous Replication\u201d guidelines there is a condition that states \u201cMultiple protection domains cannot protect the same VM.\u00a0 Configure one protection domain to protect a VM\u201d.<\/p>","quoteUsername":"Algon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我有不是我个人创建/使用任何地铁风格保护措施，我认为我在官方地铁文档/最佳实践指南中找到了您要寻找的信息的“掘金”：都会可用

搜索关键字：“异步快照工作流”

它显然说明了你想要的是支持的。

“ Nutanix支持将本地和远程快照与Metro的可用性结合使用。管理员可以安排用于地铁可用性的群集之间的快照，以及在地铁关系之外的第三个集群之间，如下图所示。”

While I have not <\/em>personally created\/used any Metro style protections, I think I found the \u2018nugget\u2019 of info you\u2019re looking for in the official Metro documentation\/best practice guide: Metro Availability<\/a><\/p>

Search for keyword: \u201cAsynchronous Snapshot Workflows\u201d<\/p>

It clearly states what you\u2019re wanting IS supported<\/strong>.<\/p>

\u201cNutanix supports the use of local and remote snapshots in combination with Metro Availability. Administrators can schedule snapshots between the clusters used for Metro Availability as well as to a third cluster outside of the Metro relationship, as shown in the following figure.\u201d<\/p>","quoteUsername":"DavidN","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我要提到的是，在某些集群情况下有一些异步限制（但主要围绕单个或双节点簇）。我还强烈鼓励打开一个“问题”票支持，以验证/确保您期望的事情会奏效……（快照/快照修剪确实占用了CPU周期，更不用说异步工作的时间是什么。接受测试/验证的W支持IMHO）。

I would mention that there ARE some Asynchronous restrictions in some cluster cases (but mostly around single or double node clusters.). I would also highly encourage to open a \u201cQuestion\u201d ticket w support to verify\/make sure things would work out as you expect it\u2026\u00a0(snapshots\/snapshot pruning does take up CPU cycles, not to mention timing of the Async job is something to be tested\/verified w support IMHO).<\/p>","quoteUsername":"DavidN","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

太好了，是的，我也读了。

这真的很有用，并感谢您如此迅速的回复。异步指南中的措辞有些误导​​。

Great, yes I read that too.<\/p>

That\u2019s really useful and thanks for replying so quickly. \u00a0The wording in the Async\u00a0guide is a bit misleading.<\/p>","quoteUsername":"Algon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
