Chapter 1 Introduction
HP NetServer AA Server Overview
The server operates as a standard Windows NT server while offering a complete fault tolerant
operating environment. The server implements the standard Windows NT operating system.
Because of this, the server supports any off-the-shelf and custom applications that are
compatible with Windows NT without requiring any scripts or API support.
To achieve full redundancy and fault tolerance, the server integrates four industry-standard
Pentium-based systems with HP’s hardware and software. As a result, the Windows NT
operating system and all network services and applications perceive the server as a single
system, as shown in Figure 1-2.

HP NetServer AA Server Hardware Configuration
With four systems integrated into a single Windows NT fault tolerant server, as shown in
Figure 1-1, the server provides complete hardware redundancy. Because the server uses
redundant hardware, its hardware availability far surpasses that of a standard Windows NT
server. Using redundant hardware also allows online service and replacement of hardware. The
server supports multiple network connections to provide additional network redundancy and
network traffic control.
