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

Table 2-1details the hardware requirements for HP-UX Directory Server:

Table 2-1 Hardware requirements

Item	Description of requirement
Computer System	HP 9000 (PA2.0) or HP Integrity system
Physical Memory	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.
