Introduction A Dell™ Failover Cluster combines specific hardware and software components to provide enhanced availability for applications and services that are run on the cluster. A Failover Cluster is designed to reduce the possibility of any single point of failure within the system that can cause the clustered applications or services to become unavailable. It is recommended that you use redundant components like server and storage power supplies, connections between the nodes and the

Cluster Solution Your cluster implements a minimum of two nodes to a maximum of either eight nodes (for Windows Server 2003) or sixteen nodes (for Windows Server 2008) and provides the following features: � 8-Gbps and 4-Gbps Fibre Channel technology � High availability of resources to network clients � Redundant paths to the shared storage � Failure recovery for applications and services � Flexible maintenance capabilities, al lowing you to repair, maintain, or upgrade a node or storage syst

Cluster Nodes Table 1-1 lists the hardware requirements for the cluster nodes. Table 1-1. Cluster Node Requirements Component Minimum Requirement Cluster nodes A minimum of two identical PowerEdge servers are required. The maximum number of nodes that are supported depend on the variant of the Windows Server operating system used in your cluster, and on the physical topology in which the storage system and nodes are interconnected. RAM The variant of the Windows Server operating system that

Cluster Storage Table 1-2 lists supported storage systems and the configuration requirements for the cluster nodes and stand-alone systems connected to the storage systems. Table 1-2. Cluster Storage Requirements Hardware Components Requirement Supported storage One to four supported Dell/EMC storage systems. See systems Table 1-3 for specific storage system requirements. Cluster nodes All nodes must be directly attached to a single storage system or attached to one or more storage systems t

Each storage system in the cluster is centrally managed by one host system ® (also called a management station) running EMC Navisphere Manager—a centralized storage management application used to configure Dell/EMC storage systems. Using a graphical user interface (GUI), you can select a specific view of your storage arrays, as shown in Table 1-4. Table 1-4. Navisphere Manager Storage Views View Description Storage Shows the logical storage components and their relationships to each other a

Supported Cluster Configurations The following sections describe the supported cluster configurations. Direct-Attached Cluster In a direct-attached cluster, all the nodes of the cluster are directly attached to a single storage system. In this configuration, the RAID controllers (or storage processors) on the storage system are connected by cables directly to the Fibre Channel HBA ports in the nodes. Figure 1-1 shows a basic direct-attached, single-cluster configuration. Figure 1-1. Direct-A

SAN-Attached Cluster In a SAN-attached cluster, all nodes are attached to a single storage system or to multiple storage systems through a SAN using redundant switch fabrics. SAN-attached clusters are superior to direct-attached clusters in configuration flexibility, expandability, and performance. Figure 1-2 shows a SAN-attached cluster. Figure 1-2.

Table 2-1. Network Connections Network Connection Description Public network All connections to the client LAN. At least one public network must be configured for Mixed mode for private network failover. Private network A dedicated connection for sharing cluster health and status information only. Figure 2-3 shows an example of cabling in which dedicated network adapters in each node are connected to each other (for the private network) and the remaining network adapters are connected to the

Cabling the Private Network The private network connection to the nodes is provided by a different network adapter in each node. This network is used for intra-cluster communications. Table 2-2 describes three possible private network configurations. Table 2-2.
