Nutanix Files是一个软件定义的、横向扩展的文件存储解决方案，具有固有的高可用性。文件服务有助于企业的重要业务功能(VDI / Home directory / Legal等)，这就是为什么Nutanix Files为文件集群虚拟机(fsvm)提供透明的HA。

当一个或多个FSVM(s)由于各种原因无法提供文件共享服务时，另一个FSVM将执行一个“接管”操作，以假定降级的FSVM的外部IP地址并共享/导出。

HA事件发生时，将External IP从降级的FSVM中移除，并导出所有共享。接管后，FSVM将导入股份/导出，并在它自己的外部网络的子接口上分配给其他FSVM外部IP。

这使得该操作对客户端是透明的，并防止客户在HA事件之前、期间或之后进行任何配置更改。

Nutanix Files提供SMB共享和NFS导出，从客户端角度来看，这两种协议在故障场景下的行为不同。

要了解更多关于SMB和NFS协议的FSVM (FILES VM) HA场景，请访问以下Nutanix KB文档:

Nutanix Files -文件服务器虚拟机HA预期行为

Nutanix Files is a software-defined, scale-out file storage solution with inherent high-availability. File services contribute to important business functions in enterprises (VDI \/ Home Directories \/ Legal etc.), which is why Nutanix Files offers transparent HA for the Files Cluster VMs (FSVMs).<\/p>

When one or more FSVM(s) are unable to serve their file-shares\u00a0for various reasons, another FSVM will perform a 'takeover' operation to assume the degraded FSVM's External IP address and shares\/exports.<\/p>

During an HA event, the External IP is removed from the degraded FSVM and all shares\u00a0exported. The FSVM taking over will then import the shares \/ exports\u00a0and be assigned the other FSVMs external IP on a sub-interface of it's own External network.\u00a0<\/p>

This allows the operation to be transparent to the client and prevents any configuration change by the customer before, during, or after the HA events.<\/p>

Nutanix Files offers both SMB shares and NFS exports, both protocols behave differently in failure scenarios from a client perspective.\u00a0<\/p>
