8 Introduction
Quorum Resource
A single shared disk, which is designated as the quorum resource, maintains
the configuration data (including all the changes that have been applied to a
cluster database) necessary for recovery when a node fails.
The quorum resource can be any resource with the following attributes:
• Enables a single node to gain and defend its physical control of the
quorum resource
• Provides physical storage that is accessible by any node in the cluster
• Uses the Microsoft Windows NT
®
file system (NTFS)
See "Quorum Resource" on page 42 and the MSCS online documentation for
more information located at the Microsoft Support website at
support.microsoft.com.
NOTE: Dell™ Windows Server Failover clusters do not support the Majority Node
Set Quorum resource type.
Cluster Solution
The Windows Server 2003 failover cluster implements up to eight cluster
nodes, depending on the storage array in use and provides the following features:
• A shared storage bus featuring Fibre Channel, Serial Attached SCSI (SAS),
or Internet Small Computer System Interface(iSCSI)technology
• 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
