This chapter contains the procedures for installing Cluster Service for servers running the
Windows 2000 server operating system.

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

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.
