你好所有的,

我对“Nutanix XCP，一个关于在Esxi使用Nutanix基础设施的原始设备映射的基本问题。Nutanix Appliance4.6 (Nos)是否支持RDM映射?如果是，是否可以共享创建裸设备共享的过程(物理模式)?

谢谢,

    你的用例是什么?

    Nutanix不使用或允许RDM的传统意义上的物理块设备挂载通过VMW vStorage堆栈;然而，如果您的用例可能是一个microsoft故障转移集群，您可以使用卷组和嵌入式iSCSI使其工作，并且它工作得很好。

    \nNutanix doesn't use or allow RDM's in the traditional sense of a physical block devices mounted through the VMW vStorage stack; however, if your use case was perhaps a microsoft failover cluster, you could use Volume Groups and in-guest iSCSI to make that work, and it works well.","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    你好乔恩,

    谢谢你的解释。实际上，我并没有将集群配置到任何与RDM相关的用例中。在走完nutanix集群和它的选项后，我找不到任何规定与RDM相关的nutanix存储配置，所以我很好奇如何实现RDM相关场景在nutanix平台。因此，我在此提出了这一关切。

    而且，我不太了解Nutanix存储堆栈中的卷组概念。你能解释一下如何在Nutanix环境中使用卷组实现RDM的用例吗

    谢谢

    \nThanks for the explanation. Actually, I am not configuring my cluster into any RDM related use case. After walk through the nutanix cluster and it options, I couldnt find any provision with related to RDM on the nutanix storage configuration so , I am curious to know about how to achive RDM related scenarios in the Nutanix platform. Hence, I raised this concern here.
    \n
    \n Also , I am not aware much about the volume groups concepts in Nutanix storage stack. Can you please explain how to achive RDM usecases using the volumegroups in Nutanix enviorment
    \n
    \nThanks

    嗨

    我有一个场景给你，我目前运行一个应用程序的虚拟机与VMware使用FC SAN和物理RDM。现在我将其迁移到Nutanix，所有的选项都是可用的。我需要在应用层做哪些改变?如。FC到ISCSI RDM ..

    问候

    不支持物理RDM。您需要将客户端iSCSI设置更改为卷组。链条中更高的是如何设置它的链接。确保你至少有专业许可。

    有几种方法可以解决这个问题。

    我更喜欢的方法是将其转换为虚拟模式RDM，然后将其存储到Nutanix的vMotion中，Nutanix实际上会将其转换为VMDK。这样你就不需要处理任何特殊的东西，它只是一个VMDK。

    \n
    \nMy preferred way is to turn this into a virtual mode RDM, and then storage vMotion it to Nutanix, which will actually turn it into a VMDK. That way you dont have to deal with anything special, its just a VMDK.","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
