LSI 500 7 Cluster Installation and Configuration

Overview	This chapter contains the procedures for installing Cluster Service for servers running the
	Windows 2000 server operating system.
Clusters	Physically, a cluster is a grouping of two independent servers that can access the same
	data storage and provide services to a common set of clients. With current technology,
	this usually means servers connected to common I/O buses and a common network for
	client access.
	Logically, a cluster is a single management unit. Any server can provide any available
	service to any authorized client. The servers must have access to the same data and must
	share a common security model. Again, with current technology, this generally means that
	the servers in a cluster will have the same architecture and run the same version of the
	same operating system.

The Benefits of Clusters Clusters provide three basic benefits:

•improved application and data availability

•scalability of hardware resources

•simplified management of large or rapidly growing systems

Software Requirements

The software requirments for cluster installation are:

•MS Windows 2000 Advanced Server or Windows 2000 Datacenter Server must be installed.

•You must use a name resolution method, such as Domain Naming System (DNS), Windows Internet Naming System (WINS), or HOSTS.

•Using a Terminal Server for remote cluster administration is recommended.
