System Requirements

Before configuring the default Red Hat Directory Server 8.0 instances, it is important to verify that the
host server has the required system settings and configuration:
• The system must have the required packages, patches, and kernel parameter settings.
• DNS must be properly configured on the target system.
• The host server must have a static IP address.
This chapter covers the software and hardware requirements, operating system patches and settings,
and system configurations that are necessary for Directory Server to perform well. It also includes
information on a Directory Server tool, dsktune, which is useful in identifying required patches and
system settings for Directory Server.
NOTE
The requirements outlined in this chapter apply to production systems. For evaluating or
prototyping Directory Server, you may choose not to meet all of these requirements.

2.1. Hardware Requirements

Red Hat recommends minimum of 200 MB of disk space for a typical installation. Large test lab
environments can require 2 GB to support the complete deployment, including product binaries,
databases, and log files. Very large directories may require 4 GB and above.
Red Hat suggests 256 MB of RAM for average environments and 1 GB of RAM for large test lab
environments for increased performance.
Table 2.1, "Hardware Requirements"
requirements based upon on the number of entries that your organization requires. The values shown
here assume that the entries in the LDIF file are approximately 100 bytes each and that only the
recommended indices are configurable.
Number of Entries
10,000 - 250,000 entries
250,000 - 1,000,000 entries
1,000,000 + entries

2.2. Operating System Requirements

Directory Server is supported on these operating systems: Red Hat Enterprise Linux 4 and 5 (x86
and x86_64), HP-UX 11i (IA 64), and Sun Solaris 9 (sparc 64-bit). The specific operating system
requirements and kernel settings, patches, and libraries are listed for each.
