第四章
• 如果您的自動化等級設定為手動（Manual）， DRS 作出較強烈的建議時（通常為
4 顆星或 5 顆星），請按照它的建議，否則叢集內的平衡與公平性會惡化。
• 讓 DRS 自動處理大部分的虛擬機器，並且設定覆寫那些您不希望讓 DRS 自動處
理的虛擬機器。
4.13 瞭解叢集狀態及警告
問題
您需要知道您的叢集內可能發生的不同狀態（State）及警告（Warning）。
解決方案
熟悉各種在 vCenter 的狀態與瞭解它們的意義。
討論
VMware 提供給管理員相關的基本資訊包括叢集的狀態、虛擬機器或是 ESXi 主機等三
種不同的警告。
例如，如果沒有冗餘網路在您的服務控制台連接埠上，您會看到一個黃色三角號誌在
您的叢集上，詳細的組態配置議題將會在摘要頁面列出，告知您有哪些組態配置警告
發生。
讓我們檢視 VMware 提供給叢集的三種不同狀態：
綠色
（
有效
）
只要它們沒有組態配置上的議題、資源過載或 ESXi 主機故障，叢集會被認定是有
效的。一個有效的叢集會有一個工作組態配置，並且所有資源將可以被虛擬機器使
用。除了所有資源都可以使用外，有效的叢集也會有一個可用的主機，提供給 ESXi
主機故障時當作備用。
黃色
（
過載
）
這個警告代表資源有潛在的風險。例如，叢集中移除主機可能會導致可用的資源儲
備低於虛擬機器所需要的等級。像是沒有冗餘網路在您的服務控制台連接埠上，這
類較輕微的組態配置議題也會觸發此狀態。
