谁能告诉我，为什么KVM使用iscsi - lun，而不是像vSphere/ESX那样使用NFS导出容器?

目前我只看到了缺点，比如处理vm很麻烦，没有看到任何好处。

    主要原因是Linux NFS驱动程序没有能力在系统上保持足够的负载来驱动最好的性能(与ESXi相比)，这就是为什么现在使用iSCSI。

    关键的部分是，所有的iSCSI vDisk创建和附加是自动处理通过我们的软件，而不是一些管理员必须手动做的事情。当在KVM上创建一个新的VM时，我们将在后台处理所有这些问题

    这里有一些甚至更酷的东西，将使KVM管理甚至比vSphere/Hyper-V更容易

    \nThe key piece is that all of the iSCSI vDisk creation and attaching is automatically handled through our software and not something the admin has to manually do. When a new VM is created on KVM we'll take care of all of this on the backend
    \n
    \nThere's some even cooler stuff coming here which will make KVM administration even easier than vSphere\/Hyper-V 🙂","quoteUsername":"TheDude","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    KVM比vSphere更灵活/适应性更强。

    据我所知，与vSphere相比，Nutanix将能够为KVM做更多的事情。

    上面的答案是最近我听到很多传言，但现在我将留在vSphere一边的事情，直到尘埃落定。

    \nAs I understand it, Nutanix will be able to do way more for KVM than for vSphere.

    \nThe answer above is one thing I've heard whispered a lot lately, but for now I'll stay on the vSphere side of things until dust settles down.
