Executive Summary
The Hewlett-Packard Pre-Failure Warranty
1
helps you run your business with
less downtime. It extends the advantage of HP’s limited warranty by providing
coverage on critical components, such as hard drives, memory and power
supplies, before they actually fail. It allows the server to monitor the status of
these critical subsystems, notifying the system administrator if the
components appear to be degrading. The Pre-Failure Warranty ensures that
when customers receive notification from system management that a critical
server component may fail, the component is replaced free of charge under
the warranty.
Whether you’re launching a business from the Web, or expanding your
current IT investments, you need to be able to keep your business up and
running 7 days a week, 24 hours a day. The HP Pre-Failure Warranty is
another tool that helps you to do just that.
A Closer Look
The cost of downtime, the time when a system is unavailable to users, can be
prohibitively expensive to a business. System configurations continue to
increase in complexity—server systems require more processors, memory,
and drives—making management and maintenance more difficult. HP,
recognizing this trend, has developed better management tools that improve
system uptime and availability. Tools that focus on problem prediction, real-
time correction and post-error recovery (key elements of a self-healing server)
provide better ways to manage critical errors that can bring down a system.
Predicting Problems
The process of predicting an event requires three different activities:
monitoring, detecting and analyzing. Monitoring entails looking at the
operating parameters of the system components. Detecting means that the
server finds the required events as they occur. Analyzing ensures that the
severity or frequency of the occurrence is understood, and if it indicates an
impending failure, then the system alerts the system administrator.

This warranty covers those HP NetServers that use HP TopTools for Servers software,
version 4.5 or higher.
