Windows Server 2003 Enterprise and Clustering

We are about to install Server 2003 Enterprise edition into 2 servers and want them clustered.  My question do you have to have a SAN or an external device in order to share the folders or can you just share between the 2 servers as a fail over?

    Accepted Solution

    You have to have a common shared storage (the quorum drive), protected by the cluster service.

    This is from technet:
    "The following are general hardware requirements for building Windows Server 2003 clusters. More detailed information is provided throughout this chapter where applicable. In order for server clusters to be supported by Microsoft, all hardware must be selected from a list of qualified clustering solutions. See the Windows Server Catalog link on the Web Resources page at For more information about support for server clusters, see article Q309395, "The Microsoft Support Policy for Server Clusters and the Hardware." To find this article, see the Microsoft Knowledge Base link on the Web Resources page at

    Use a minimum of two computers running Windows Server 2003, Enterprise Edition or Windows Server 2003, Datacenter Edition (computer hardware must also be listed in the Windows Server Catalog). You cannot mix x86-based and Itanium architecture–based computers in the same server cluster.

    Meet minimum storage requirements. Minimum storage requirements depend on a number of factors, such as whether or not your server cluster uses storage area network (SAN) technology, or the type of quorum resource used in the server cluster. For more information about storage solutions, see "Designing the Support Structure for Server Clusters" later in this chapter. Note that all storage solutions must also be listed in the Windows Server Catalog.

    Use a minimum of two network adapters for each node. In recommended configurations, one network adapter connects the node to the other nodes in the cluster for communication and configuration purposes (private network). The second adapter connects the cluster to both an external network (public network) and the private network. "

    So does this mean you have to have an external shared storage?  You can't create a cluster between 2 servers and have them share between each other without an external shared storage?
