    Dell|EMC storage arrays. NOTE: Throughout this document, PowerVault NX1950 storage system refers to the individual cluster node. PowerVault NX1950 cluster solution refers to the configuration of two or more PowerVault NX1950 storage systems running ® Microsoft Cluster Services (MSCS) attached to either PowerVault MD3000 storage array or a Dell|EMC storage array.

  • Page 8: Nodes

    For more information about MSCS features and functionality, see the Microsoft Support website at support.microsoft.com. Nodes Nodes or cluster nodes refer to the PowerVault NX1950 storage systems that are members of the cluster. The PowerVault NX1950 storage solution supports a multiple-node cluster.

  • Page 9: Quorum Resource

    To enable the PowerVault NX1950 configuration as a cluster, the quorum disk must be deployed on a shared storage disk. The PowerVault NX1950 cluster solution is deployed as a Shared storage solution by default to ensure that the quorum disk can be created and mapped to both the nodes in the cluster.

  • Page 10: Configuration Tools

    Dell provides a batch file that sets the required port exceptions to deploy, manage, and use the PowerVault NX1950 cluster solution.

  • Page 11: Supported Operating System

    The Microsoft Windows Unified Data Storage Server 2003, Standard x64 Edition is supported on the PowerVault NX1950 storage system as a stand-alone solution only. You can purchase an upgrade kit from Dell to upgrade to the Windows Unified Data Storage Server 2003, Enterprise x64 Edition.

  • Page 15: Prerequisites For Cabling Your Cluster

    Prerequisites for Cabling Your Cluster You must set up at least two LAN connections to enable your storage solution as a cluster. The PowerVault NX1950 cluster solution uses one or more connections for client access (public) IP addresses and a dedicated connection for heartbeat (private) network.

  • Page 16: Cabling Your Integrated Solution

    Figure 2-2 shows the supported cable configuration for the PowerVault NX1950 cluster solution. You must connect the SAS 5/E Adapters on both the PowerVault NX1950 storage systems to the PowerVault MD3000 storage array to enable the storage systems as cluster nodes. For your Ethernet port connection, It is recommended that you use the on-board connections for the public network.

    NOTE: You can also access the PowerVault NX1950 Initial Configuration Tasks wizard from the PowerVault NX1950 Management Console. To launch this wizard, click Edit server configuration located in the right pane of the window as highlighted in the Figure 2-1 below.
  • Page 20 1. Perform the following procedure to create a cluster: 1 Go to the PowerVault NX1950 Storage Tasks wizard. 2 In the Customize this System section, click Create or Join Cluster.
  • Page 21 4 After the quorum disk is created, the New Server Cluster Wizard appears. This wizard takes you though the process of cluster creation. Click Next to begin the process. 5 The Analyzing Configuration window appears and the system configuration is analyzed. If a cluster configuration already exists, this step fails.
  • Page 22 NOTE: This wizard gives you an option to add additional nodes to the cluster. The PowerVault NX1950 cluster solution supports only two nodes with the PowerVault MD3000 storage array (Integrated Solution) and up to eight nodes with the Dell|EMC storage arrays (Gateway Solution).
  • Page 23 14 The Welcome to the Add Nodes screen appears. Click Next to continue. 15 The Cluster Name and Domain screen appears. Enter the cluster name and domain of the cluster that you want to join and click Next. 16 The Select Computers screen appears. This dialog box allows you to add additional nodes to the cluster.
  • Page 24 20 If the node is successfully added, the progress bar is green. If there are any errors, the progress bar is red. Click Back to fix any configuration errors that caused the failure. After the errors are corrected and the progress bar is green, click Next.

  • Page 25: Managing Your Cluster

    NOTE: When you create a Highly-Available Server Instance on a cluster node using the PowerVault NX1950 Initial Configuration Tasks wizard, the status of the Highly-Available Server Instance is not visible to the other nodes within the cluster. This behavior is expected and is behaving as designed. To access the Highly- Available Server Instance, each node in the cluster must have ownership of the instance.
