ProLiant Cluster for NetWare 4.2 Overview
Novell products are designed to support incremental network growth, and the ProLiant Cluster for
NetWare 4.2 continues this philosophy with its solid NetWare environment designed to provide
both industrial-strength availability and scalability at the hardware, operating system, and
application levels.
By deploying the ProLiant Cluster for NetWare 4.2, your company can reduce downtime and
operating costs. At the same time, your network can benefit from the latest Internet/intranet and
file and print services in a robust network environment for deploying general-purpose
applications.

Novell’s High-Reliability Solution
The ProLiant Cluster for NetWare 4.2, featuring Novell High Availability Server (NHAS),
increases network reliability through the use of two NetWare 4.11 or NetWare 4.2 servers with a
shared disk subsystem. By pairing two independent servers in an active-active configuration, the
NHAS allows each server to access and mount the other server's data if there is a failure on a
server in the cluster.
Each server monitors the status of the other server over three redundant lines of communication:
•
NetWare Link – each server can monitor the presence of the other across the local network.
•
Disk Link – NHAS
uses quorum arbitration to allow each server to monitor the other server’s
shared storage connection and prevent concurrent access to the same data.
•
Optional Dedicated Link – by creating a dedicated link between the two servers, each server
can monitor the presence of the other more reliably, eliminating false failures caused by
network traffic or prolonged disk inactivity.
