Computer System Requirements; Summary Of Supported Platforms; 32-Bit Process - Red Hat DIRECTORY SERVER 7.1 Installation Manual

Computer System Requirements

Before you can install Red Hat Directory Server (Directory Server), you must make sure that the
systems on which you plan to install the software meet the minimum hardware and operating system
requirements.
Directory Server is compiled as a 64-bit application for some platforms, meaning Directory Server
supports deployments with memory cache sizes larger than 4 GB and limited only by available mem-
ory.
It is possible to use Directory Server as a 32-bit application on supported 32-bit platforms. On 64-bit
platforms, if the memory cache size is smaller than 4 GBs, it is recommended that you run the 32-bit
application of Directory Server since this may improve performance. Be sure that you have the correct
application for your Directory Server deployment.
These requirements are described in detail for each platform in the following sections:
Section 2.1 Summary of Supported Platforms
•
Section 2.2 Hardware Requirements
•
Section 2.3 Operating System Requirements.

performance on large production systems.
Approximately 300 MBs of disk space for a minimal installation. For
production systems, you should plan at least 2 GB to support the
product binaries, databases, and log files (log files require 1 GB by
default); 4 GB and greater may be required for very large directories.
