Operating System Requirements
Chapter 2 Computer System Requirements 27
• Roughly 200Mbyte of disk space for a minimal installation. For production
systems, you should plan at least 2
Gbyte to support the product binaries,
databases, and log files (log files require 1
Gbyte by default); 4Gbyte and greater
may be required for very large directories.
•256
Mbyte of RAM. However, you should plan for 1Gbyte of RAM for best
performance on large production systems.
The table below contains some guidelines for disk space and memory requirements
depending on the number of entries managed by your Directory Server. This
assumes entries in the LDIF file are approximately 100 bytes in size and only the
recommended indexes are configured. If you are using larger entries, make sure
that at least four times the size of the LDIF file is available on disk.
