Server 2003 cluster 節點之間是否可以跨網段 RRS feed

  • 問題

  • 各位vip您好:

         小弟有兩個問題請教,

    問題一:client在使用XP 登入網域時,能不能隱藏底下的網域名稱

    問題二:請問 win server 2003 內的cluster 功能可否跨網段偵測 並如發生故障時以手動切換 ??

解答

  • 我又查了一下 , 跨網段的Cluster在Server 2003是不可行的 , 在Server 2008開始才支援

    參考資訊:

    摘錄:
    Starting in Windows Server 2008 Failover Clustering nodes can communicate with each other across a router (this is often referred to as the multi-subnet or cross-subnet support), which is very important in supporting our multi-site clustering scenarios.

    Thanks

所有回覆

  • 一般來說 , Cluster的所有Nodes建議都放在同一個網段下 , 而且連接Nodes的網路建議不要有其它網路設備(Router , Switch)或是一些應用程式伺服器在裡面

    參考資訊
    Quick Start Guide for Server Clusters
    http://technet.microsoft.com/zh-tw/library/cc739757(WS.10).aspx

    摘錄其中一些資訊如下

    Setting up networks

    Each cluster node requires at least two network adapters and must be connected by two or more independent networks. At least two LAN networks (or virtual LANs) are required to prevent a single point of failure. A server cluster whose nodes are connected by only one network is not a supported configuration. The adapters, cables, hubs, and switches for each network must fail independently. This usually means that the components of any two networks must be physically independent.

    Two networks must be configured to handle either All communications (mixed network) or Internal cluster communications only (private network). The recommended configuration for two adapters is to use one adapter for the private (node-to-node only) communication and the other adapter for mixed communication (node-to-node plus client-to-cluster communication).

    You must have two PCI network adapters in each node. They must be certified in the Microsoft Windows Catalog and supported by Microsoft Product Support Services. Assign one network adapter on each node a static IP address, and assign the other network adapter a static IP address on a separate network on a different subnet for private network communication.

    Because communication between cluster nodes is essential for smooth cluster operations, the networks that you use for cluster communication must be configured optimally and follow all hardware compatibility-list requirements. For additional information about recommended configuration settings, see article 258750, "Recommended private heartbeat configuration on a cluster server," in the Microsoft Knowledge Base.

    You should keep all private networks physically separate from other networks. Specifically, do not use a router, switch, or bridge to join a private cluster network to any other network. Do not include other network infrastructure or application servers on the private network subnet. To separate a private network from other networks, use a cross-over cable in a two-node cluster configuration or a dedicated hub in a cluster configuration of more than two nodes.

    Additional network considerations

    • All cluster nodes must be on the same logical subnet.
    • If you are using a virtual LAN (VLAN), the one-way communication latency between any pair of cluster nodes on the VLAN must be less than 500 milliseconds.
    • In Windows Server 2003 operating systems, cluster nodes exchange multicast heartbeats rather than unicast heartbeats. A heartbeat is a message that is sent regularly between cluster network drivers on each node. Heartbeat messages are used to detect communication failure between cluster nodes. Using multicast technology enables better node communication because it allows several unicast messages to be replaced with a single multicast message. Clusters that consist of fewer than three nodes will not send multicast heartbeats. For additional information about using multicast technology, see article 307962, "Multicast Support Enabled for the Cluster Heartbeat," in the Microsoft Knowledge Base.

    Thanks

  • Vincent Lin 您好:

        感謝您熱心的回答,所以,官方只建議在同網段,那在不同網段做cluster是可行的嗎?會有什麼樣的風險呢?THX!
