HP-UX Directory Server 8.1 installation guide

2 System requirements
Before configuring the default HP-UX Directory Server 8.1 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.
System settings, like the number of file descriptors and TCP information, should be reconfigured
to optimize the Directory Server performance.
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.
NOTE:
The requirements outlined in this chapter apply to production systems. For evaluating or
prototyping Directory Server, you may choose not to fulfill all these requirements.
2.1 Hardware requirements

At least 256 MB of memory.
HP recommends that you have 512 MB to 4 GB of memory for best performance on large
production systems.
The physical memory requirements for each Directory Server process depend on your
particular configuration and database. Each server process requires at least 15 MB of memory.
However, the server caches recently used entries. Depending on the size of the database
served and the size of the entries cached, the memory requirements for a typical Directory
Server process can exceed 2 GB.
