8 Introduction
The following list includes basic features of MSCS:
• Highly-available and server consolidation
• Deployable on a single network
• Multiple-node cluster support
NOTE: The multiple-node cluster is supported on PowerVault NX1950 cluster
solution with Windows Unified Data Storage Server 2003, Enterprise x64
Edition operating system only.
For more information about MSCS features and functionality, see the
Microsoft Support website at support.microsoft.com.
Nodes
Nodes or cluster nodes refer to the PowerVault NX1950 storage systems that
are members of the cluster. The PowerVault NX1950 storage solution supports
a multiple-node cluster.
Cluster Resources
The cluster resources are physical or logical entities with the following
characteristics:
• Can be brought online/offline
• Can be managed within a cluster
• Can be hosted by one node within the cluster
Examples of resources are Network Name, IP addresses, services, applications,
and disk storage. During cluster failover, only the cluster resources failover to
another node.
The PowerVault NX1950 cluster solution supports cluster resources and you
can use the cluster administration tools to configure them. For more
information about cluster administration tools, see "Cluster Administration
and Management" on page 12.
Resource Group
A resource group is a group of resources (IP addresses, disk storage) that can
failover as a unit. An example of a resource group is a Highly-Available Server
Instance.
