在学习AHV的时候，我在一些事情上有点困惑，因为它涉及租户和远程站点。
- 租户的用途是什么，与container有什么区别?
- 将Site-A的租户(Container-A)映射到Site-B的租户(Container-B)，其中有运行中的虚拟机，有什么影响?
- 不包括Site-A的容器- a中的所有虚拟机在保护域中和故障转移说PD到Site-B的影响是什么?—来自Container-A的不受保护的虚拟机在Site-A上是否继续运行?-如果我把警局调到a区会怎么样?
- 假设我已经将容器a (Site-A)映射到容器b (Site-B)。如果我创建了一个包含了来自Container-A2 (Site-A)的虚拟机的保护域，该如何影响站点之间的租户映射?
谢谢你的帮助!

- What is the purpose of a vStore and how do they differ from Containers?\u00a0<\/strong><\/li> <\/ul>
vStore<\/strong><\/p>
A separate mount point within a storage container which has its own NFS namespace. This namespace maps to a Protection Domain. Each vStore is exported as a device through the Nutanix SRA.<\/p>
\u00a0<\/p>
storage container<\/strong><\/p>
A subset of available storage within a storage pool.<\/p>
- What are the implications of mapping a Site-A\u2019s vStore (Container-A) to Site-B\u2019s vStore (Container-B) that has running VMs in it?<\/strong><\/li> <\/ul>
By just mapping Site A\u2019s Container A with Site B\u2019s Container B there are no implications.\u00a0 It just defines the source and destination at the time of replication. So when we start replicating the data between both sites the VM disks located in Container A of Site A will send data to the VM disk located in the Container B of Site B. Those VMs are protected under Protection Domain<\/p>
\u00a0<\/p>
- What are the implications of not including all VMs from within Site-A\u2019s Container-A in a Protection Domain and failing-over said PD to Site-B?\u00a0 \u00a0 \u00a0 - Will the unprotected VMs from Container-A continue to run in Site-A?\u00a0 \u00a0 \u00a0 - What happens when I fail-back the PD to Site-A?<\/strong><\/li> <\/ul>
If the VMs are not protected under the Protection Domain then failover doesn\u2019t happen. Failover or Failback works only for the VMs which are part of the Protection Domain\u00a0<\/p>
- Let\u2019s say I\u2019ve mapped Container-A (Site-A) to Container-B (Site-B). If I create a Protection Domain that contains VMs from Container-A2 (Site-A), how does this factor into my vStore mappings between sites?<\/strong><\/li> <\/ul>
In that case, if you don\u2019t do store mapping of the Container -A2 then by default, it will be mapped to default Container on SIte B ( SelfService Container) But Best practice is to map explicitly\u00a0 as we did for Container A and Container B.<\/p>

Please refer DR guide for more explanation and failover scenarios<\/p>
