Windows Server 容錯Failover Clustering in Windows Server

適用於:Windows Server(以每年次管道)、Windows Server 2016Applies To: Windows Server (Semi-Annual Channel), Windows Server 2016

Icon indicating a group of computers -Windows Server 功能可讓您在多部伺服器分組到容錯叢集-容錯提供軟體定義 datacenter 針對的全新改良功能和實體硬體或電腦虛擬執行叢集許多其他工作負載。Failover clustering - a Windows Server feature that enables you to group multiple servers together into a fault-tolerant cluster - provides new and improved features for software-defined datacenter customers and many other workloads running clusters on physical hardware or in virtual machines.

容錯移轉叢集是群組的獨立合作來增加可用性電腦和延展性叢集角色(先前稱為叢集應用程式與服務)。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). 由實體的纜長度和軟體連接(稱為節點)叢集的伺服器。The clustered servers (called nodes) are connected by physical cables and by software. 如果有一或多個節點叢集失敗,其他節點開始提供的服務(處理程序稱為容錯移轉)。If one or more of the cluster nodes fail, other nodes begin to provide service (a process known as failover). 此外,以檢查它們正常運作會主動監視叢集的角色。In addition, the clustered roles are proactively monitored to verify that they are working properly. 如果無法使用時,它們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.

容錯也提供提供一致且分散命名空間叢集角色叢集共用磁碟區 (CSV) 功能可以存取所有節點共用存放裝置。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. 藉由容錯的功能,使用者體驗的服務中斷。With the Failover Clustering feature, users experience a minimum of disruptions in service.

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

  • Microsoft SQL Server,而且 HYPER-V 虛擬電腦應用程式的可用性或持續提供檔案共用儲存空間Highly available or continuously available file share storage for applications such as Microsoft SQL Server and Hyper-V virtual machines
  • 虛擬電腦已執行於 HYPER-V 的伺服器上安裝或實體伺服器上執行的可用性叢集的角色Highly available clustered roles that run on physical servers or on virtual machines that are installed on servers running Hyper-V

新功能What's new

以下是一些在 Windows Server 2016-中的新功能的詳細資訊,請查看容錯中的新功能 :Here are some of the new features in Windows Server 2016 - for more details, see What's new in Failover Clustering:

叢集作業系統循環升級Cluster operating system rolling upgrades

讓系統管理員而停止 HYPER-V 或延展檔案伺服器工作負載升級叢集節點的作業系統。Enables an administrator to upgrade the operating system of the cluster nodes from without stopping the Hyper-V or the Scale-Out File Server workloads.

雲端見證容錯移轉叢集Cloud Witness for a Failover Cluster

新類型的仲裁見證,以協助您判斷要叢集節點 Microsoft Azure 會運用被視為節點離線授權。A new type of quorum witness that leverages Microsoft Azure to help determine which cluster node should be considered authoritative if a node goes offline.

健康服務Health Service

改善日常監視、作業及維護儲存空間直接存取群集的體驗。Improves the day-to-day monitoring, operations, and maintenance experience of Storage Spaces Direct clusters.

錯誤網域Fault Domains

可讓您定義與儲存空間直接存取叢集使用何種錯誤網域。Enables you to define what fault domain to use with a Storage Spaces Direct cluster. 硬體分享單點伺服器] 節點、底座伺服器,或架失敗,錯誤網域。A fault domain is a set of hardware that share a single point of failure, such as a server node, server chassis, or rack.

VM 負載平衡VM load balancing

協助載入平均分散辨識忙碌節點,將 Vm live 移轉至較忙碌節點這些節點上的容錯移轉叢集節點上。Helps load be evenly distributed across nodes in a Failover Cluster by identifying busy nodes and live-migrating VMs on these nodes to less busy nodes.

簡化的 SMB 多頻道,使用多監視器-NIC 叢集網路Simplified SMB Multichannel and multi-NIC cluster networks

可以用來變得更容易叢集中的多個網路介面卡設定。Enables easier configuration of multiple network adapters in a cluster.
