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 DIB Set as the hardware allows.
eDirectory scales well on a single processor. However, Novell eDirectory 8.7.3 takes advantage of multiple processors. Adding processors improves performance in some areas---for example, logins and having multiple threads active on multiple processors. eDirectory itself is not processor intensive, but it is I/O intensive.
The following table illustrates typical system requirements for eDirectory for Linux:
| Objects | Processor | Memory | Hard Disk |
|---|---|---|---|
100,000 |
Pentium III 450-700 MHz (single) |
384 MB |
144 MB |
1 million |
Pentium III 450-700 MHz (dual) |
2 GB |
1.5 GB |
10 million |
Pentium III 450-700 MHz (2 to 4) |
2+ GB |
15 GB |
Requirements for processors might be greater than the table indicates, depending upon additional services available on the computer as well as the number of authentications, reads, and writes that the computer is handling. Processes such as encryption and indexing can be processor intensive.
