Hardware tuning

Consideration to improve disk speed

If a directory server contains millions of entries, it can become impossible to cache all of the entries in memory. Even if you are able to cache a directory with small number of entries, update operations require to access disk. The speed of disk operations is important. You can consider the following points to improve the disk drive performance:

• Use fast disk drives
• Use a hardware write cache
• Spread data across multiple disk drives
• Spread the disk drives across multiple I/O controllers
• Store log files and data on separate physical disk drives
• Use raw devices for storing the table space data
