Introduction A 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 storag

Cluster Solution Your cluster implements a minimum of two node to a maximum of either eight nodes (for Windows Server 2003) or sixteen nodes (for Windows Server 2008) clustering and provides the following features: � 8-Gbps and 4-Gbps Fibre Channel technologies � 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

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 Dell™ PowerEdge™ servers are required. The maximum number of nodes that is supported depends 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 sys

Cluster Storage Cluster nodes can share access to external storage systems. However, only one of the nodes can own any redundant array of independent disks (RAID) volume in the external storage system at any time. Microsoft Cluster Services (MSCS) controls which node has access to each RAID volume in the shared storage system. 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

Cabling the Public Network Any network adapter supported by a system running TCP/IP may be used to connect to the public network segments. You can install additional network adapters to support additional public network segments or to provide redundancy in the event of a faulty primary network adapter or switch port. 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 communic

Using Dual-Port Network Adapters You can configure your cluster to use the public network as a failover for private network communications. If dual-port network adapters are used, do not use both ports simultaneously to support both the public and private networks. NIC Teaming NIC teaming combines two or more NICs to provide load balancing and fault tolerance. Your cluster supports NIC teaming, but only in a public network; NIC teaming is not supported in a private network. You should use
