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 HP-UX 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 HP-UX 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 HP- UX 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 Migrating Sun 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”.
