The Dell

PowerEdge
®
Cluster FE100 is an enterprise system that implements clus-
tering technology based on the Microsoft
®
Windows NT
®
Server, Enterprise Edition
4.0 operating system and the Microsoft Windows NT Cluster Server. The PowerEdge
Cluster FE100 provides the following benefits in meeting the needs of mission-critical
network application programs:
High availability of system services and resources to network clients
Redundant storage of application program data
Failure recovery for cluster application programs
Capability to repair, maintain, or upgrade a cluster node without taking the entire
cluster off-line
Sharing of processing and communication workload between the two servers
The term
cluster
refers to two or more identical server systems (referred to as
nodes
)
that are interconnected with appropriate hardware and software to provide a single
point of continuous access to network services (for example, file service, database
application programs, and resources) for network clients.
Each node is configured with software and network resources that enable it to inter-
act with the other node to provide a mutual redundancy of operation and application
program processing. Because the nodes interact in this way, they appear as a single
system to the network clients.
As an integrated system, the PowerEdge Cluster FE100 is designed to handle most
hardware failures and downtime dynamically. In the event that one of the nodes fails
or experiences downtime, the processing workload of the failed node switches over
(or
fails
over
) to the remaining node in the cluster. This fail-over capability enables the
cluster system to keep network resources and application programs running on the
network while the failed node is taken off-line, repaired, and brought back online. The
overall impact of a node failure to network operation is minimal.
