2.3 Hardware Requirements

Hardware requirements depend on the specific implementation of eDirectory. Two factors increase performance: more cache memory and faster processors. For best results, cache as much of the Directory Information Base (DIB) Set as the hardware allows.

eDirectory scales well on a single processor. However, NetIQ eDirectory 9.1 takes advantage of multiple processors. Adding processors improves performance in some areas — for example, logins — and having multiple threads active on multiple processors also improves performance. eDirectory itself is not processor intensive, but it is I/O intensive.

The following table illustrates typical system requirements for eDirectory for Linux:
