Overview

Product overview

The HP-UX Directory Server version 8.1 provides an industry standard centralized directory service
upon which to build your intranet or extranet. Your directory-enabled applications use the directory
service as a common, network-accessible location for storing shared data such as user and group
identification, server identification, and access control information. In addition, you can extend the
HP-UX Directory Server to support your entire enterprise with a global directory service that provides
you with centralized management of all your enterprise's resource information. For more information
about features provided by the latest version of the HP-UX Directory Server, see the current

Directory Server release notes.

The HP-UX Directory Server 8.1 product replaces the Red Hat Directory Server for HP-UX (RHDS)
product line. The HP-UX Directory Server is based on the same open source software as RHDS
and includes a straightforward migration process from RHDS, which is documented in the

Directory Server installation guide. HP-UX Directory Server shares a common heritage with Sun Java

System Directory Server (SJDS) and has almost identical features and capabilities. This helps provide
SJDS consumers a smooth transition from their product to the HP-UX Directory Server. Because the HP­UX Directory Server provides a stable platform based on current industry standards, it is supportable
for the long term. HP provides a script with the HP-UX Directory Server software that facilitates
migrating data from SJDS. For more information about migrating from SJDS, see the

Java System Director Server to HP-UX Director Server white paper.

Purpose of this document

This document provides basic sizing and performance tuning guidelines for HP-UX Directory Server
(HPDS) version 8.1 for HP-UX 11i v3 on Integrity servers. It also provides the performance test results
of HPDS 8.1 on HP-UX Integrity servers. The HPDS 8.1 is a 64-bit directory server.

The data provided here is intended to help system and network administrators to effectively size and
tune different directory server configurations. This paper covers major topics such as class of
machines, amount of memory, and number of CPUs. This document also discusses how to tune some
of the key performance-related attributes for HPDS.

Note: Data presented in this document is measured under a controlled environment with dedicated
HP-UX servers connected by a private LAN. No other system activities were running during the
performance testing. For HPDS 8.1 performance test details, see “Appendix A: HPDS 8.1
performance test details”.

Sizing and tuning overview

This section provides a brief overview of hardware and tuning recommendations for optimal
performance of the HP-UX Directory Server 8.1. More detailed guidelines for hardware sizing and
tuning, and the actual parameters used for performance testing reported in this white paper, are
provided in the “Sizing and Tuning Recommendations” section.
