Windows Server 中的容錯移轉叢集Failover Clustering in Windows Server

適用於:Windows Server 2019、Windows Server 2016Applies to: Windows Server 2019, Windows Server 2016

容錯移轉叢集是由獨立電腦組成的群組,它們共同運作以提升叢集角色 (之前稱為叢集應用程式和服務) 的可用性及擴充性。A failover cluster is a group of independent computers that work together to increase the availability and scalability of clustered roles (formerly called clustered applications and services). 各個叢集伺服器 (稱為節點) 是透過實體纜線與軟體連接。The clustered servers (called nodes) are connected by physical cables and by software. 如果其中一或多個叢集節點失敗,其他節點即會透過稱為「容錯移轉」的程序開始提供服務。If one or more of the cluster nodes fail, other nodes begin to provide service (a process known as failover). 不僅如此,叢集角色還會主動監看以確認服務正常運作。In addition, the clustered roles are proactively monitored to verify that they are working properly. 如果服務沒有運作,就會重新啟動或移到另一個節點。If they are not working, they are restarted or moved to another node.

容錯移轉叢集也提供叢集共用磁碟區 (CSV) 功能,此功能提供一致的分散式命名空間,叢集角色可使用這個空間從所有節點存取共用存放空間。Failover clusters also provide Cluster Shared Volume (CSV) functionality that provides a consistent, distributed namespace that clustered roles can use to access shared storage from all nodes. 透過容錯移轉叢集功能,使用者幾乎不會感覺到服務中斷的情況。With the Failover Clustering feature, users experience a minimum of disruptions in service.

容錯叢集有許多實用的應用程式,包括:Failover Clustering has many practical applications, including:

  • Microsoft SQL Server 和 Hyper-V 虛擬機器之類應用程式的高可用性或持續可用的檔案共用儲存區Highly available or continuously available file share storage for applications such as Microsoft SQL Server and Hyper-V virtual machines
  • 在實體伺服器或安裝在執行 Hyper-V 伺服器的虛擬機器上執行的高可用性叢集角色Highly available clustered roles that run on physical servers or on virtual machines that are installed on servers running Hyper-V
