Hardware Requirements
Hardware requirements depend on the specific implementation of NDS.
For example, a base installation of NDS 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.
NDS scales well on a single processor. However, NDS eDirectory 8.5 takes advantage of
multiple processors. Adding processors improves performance in some areas, for
example, logins and having multiple threads active on multiple processors. NDS itself is
not processor-intensive, but it is I/O-intensive.
The following table illustrates typical system requirements for NDS 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 NDS can then cache more of the directory into memory.
Forcing the Backlink Process to Run
Because the internal NDS identifiers change when upgrading to NDS eDirectory, the
backlink process has to update backlinked objects for them to be consistent.
