嗨,团队,

我对nutanix和esx的迁移过程有疑问，

我可以在现有的vcenter上加入现有集群中的nutanix节点吗，我现有节点的处理器和我新的nutanix节点是相同的，并且evc是启用的，所以我可以加入nutanix和通用服务器在同一个集群中吗?

Hi teams,<\/p>

\u00a0<\/p>

i have question about migration process in nutanix and esx,<\/p>

can i joining nutanix node in existing cluster on existing vcenter, processor in my existing node and my new nutanix node is same, and evc is enable, so can i joining nutanix and general server in same cluster?<\/p>","quoteUsername":"randyramandani","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嘿 @randyramandani
我对它的用例很好奇，而不是将它设置为同一个vCenter下的独立集群。
我认为，如果将非Nutanix和Nutanix节点组合在同一个集群中，可能会遇到问题，主要是因为它们不容易共享相同的存储。

从vCenter的角度来看，即使您设置了对Nutanix数据存储的访问，您的非Nutanix节点也不会将其视为相同的数据存储。这是因为Nutanix节点上的数据存储和需要访问的内部开关192.168.5.2,但这个地址不是访问外部(和真的不可能,因为每一个主机都有这个IP地址由当地CVM,因此必须在主机,以避免一个孤立的网络IP地址冲突。)

当多个主机上的NFS数据存储名称、NFS服务器IP地址和挂载路径相同时，vCenter将一个NFS数据存储视为“相同的数据存储”。对于所有的Nutanix节点，它们正在访问192.168.5.2:/container-name，这意味着您可以在它们之间迁移虚拟机，而不需要迁移存储。对于任何其他ESXi主机访问相同的容器，它将需要使用:/container-name和vCenter将这解释为一个不同的数据存储。这在vCenter库存中变得有点混乱。

如果你正在考虑将Nutanix节点连接到ESXi的传统数据存储上，我建议你不要这么做。请看文章“第三方存储可能会导致Nutanix系统上的问题，以了解更多细节。

Hey\u00a0@randyramandani<\/user-mention>\u00a0
I\u2019m curious about the use case for this, versus setting it up as a separate cluster under the same vCenter.\u00a0
I think you might run into issues if you\u2019re combining non-Nutanix and Nutanix nodes in the same cluster, primarily since they wouldn\u2019t easily share the same storage.

From a vCenter perspective your non-Nutanix nodes would not see the Nutanix datastore as the same datastore even if you set up access to it. This is because on the Nutanix nodes the datastore is (and needs to be) accessed on the internal switch at 192.168.5.2, but this address isn\u2019t accessible externally (and really can\u2019t be, since every host has this IP address presented by the local CVM, thus it must be an isolated network within the host to avoid IP address conflict.)\u00a0

vCenter sees an NFS datastore as \u201cthe same datastore\u201d across multiple hosts when the datastore name,\u00a0NFS server IP address, and mount path are the same. For all the Nutanix nodes they are accessing 192.168.5.2:\/container-name and this means you can migrate VMs between them without storage migration.\u00a0\u00a0For any other ESXi host to access that same container it would need to use the <cluster virtual IP>:\/container-name and vCenter would interpret this as a different datastore. This gets a bit messy in the vCenter inventory.\u00a0

If you\u2019re looking at attaching the Nutanix nodes to your traditional datastores for ESXi, I\u2019d have to advise against it. See the article \u201c3rd party storage might cause issues on a Nutanix system<\/a>\u201d for more details.\u00a0<\/p>","quoteUsername":"JeremyJ","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
