HARDWARE REQUIREMENTS
Hardware requirements depend on the specific implementation of eDirectory.
For example, a base installation of eDirectory with the standard schema requires about 74 MB of
disk space for every 50,000 users. However, if you add a new set of attributes or completely fill
in every existing attribute, the object size grows. These additions affect the disk space,
processor, and memory needed.
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 8.6 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 NetWare:
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.
Of course, faster processors improve performance. Additional memory also improves
performance because eDirectory can then cache more of the directory into memory.
FORCING THE BACKLINK PROCESS TO RUN
Because the internal eDirectory identifiers change when upgrading to Novell eDirectory, the
backlink process has to update backlinked objects for them to be consistent.
