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, allowing you to repair, maintain, or upgrade a node or storage system without taking the entire cluster offline Implementing Fibre Channel technology in a cluster provides the following advantages: • Flexibility - Fibre Channel allows a distance of up to 10 km between switches without degrading the signal. • Availability - Fibre Channel components use redundant connections, providing multiple data paths and greater availability for clients. • Connectivity - Fibre Channel allows more device connections than SCSI. Because Fibre Channel devices are hot-swappable, you can add or remove devices from the nodes without bringing down the cluster.

Introduction
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, allowing you to repair, maintain, or
upgrade a node or storage system without taking the entire cluster offline
Implementing Fibre Channel technology in a cluster provides the following
advantages:
•
Flexibility
— Fibre Channel allows a distance of up to 10 km between
switches without degrading the signal.
•
Availability
— Fibre Channel components use redundant connections,
providing multiple data paths and greater availability for clients.
•
Connectivity
— Fibre Channel allows more device connections than
SCSI. Because Fibre Channel devices are hot-swappable, you can add or
remove devices from the nodes without bringing down the cluster.
Cluster Hardware Requirements
Your cluster requires the following hardware components:
•
Cluster nodes
•
Cluster storage
