Nutanix群集需要三个节点,但Nutanix还提供了两个节点簇的选项。通过在配置单独的故障域中配置外部证人VM,提供了三节点群集的弹性功能。

要求:

  • 控制器VM最低要求:6 VCPU和20 GB内存

  • 复制因子(RF):RF2在两个节点上的SSD上的两个节点上跨越两个节点,RF4跨越RF4。元数据的RF4在节点故障场景中有助于快速过渡健康节点,以在单节点模式下运行,而元数据剩余的磁盘容错可容纳。(两个节点群集中的元数据通常很小,因此四个副本的存储需求适中。)

  • 驱动失败效果:一个节点 +一个SSD故障(在另一个节点上)=仅读取模式。

指南:

  • 仅在选择的一组硬件模型上支持两个节点簇。有关支持模型的信息,请参见KB 5943。支持的模型

  • 由于在单个节点和两个节点状态之间过渡时同步数据的附加步骤,因此两个节点群集中的升级过程可能比通常的过程更长。然而,该集群在升级期间仍在运行。

  • 使用外部DNS和NTP服务器。Nutanix建议您在另一个集群上托管DNS和NTP服务器。

  • 不支持节点去除,但是支持节点置换(该节点保留群集的一部分)。替换节点时,群集保持活跃,但会在短时间内过渡到独立模式。

配置证人

  • 要通过配置证人选项配置证人,请执行以下操作:

  • 获取目标证人VM(IP地址,用户名和密码)的凭据。

  • 单击主菜单中的齿轮图标,然后在“设置”页面中选择“配置见证”(请参阅​​设置菜单)。

  • 在“配置见证”窗口中,在指示字段中输入证人VM IP地址,用户名和密码,然后单击“保存”按钮。
