Installing or Upgrading Novell eDirectory on Windows 25novdocx (en) 6 April 2007Configuring Static IP AddressRefer to “Configuring Static IP Address” on page 12 for more information on configuring static IPaddresses.2.3 Hardware RequirementsHardware requirements depend on the specific implementation of eDirectory.For example, a base installation of eDirectory with the standard schema requires about 74 MB ofdisk space for every 50,000 users. However, if you add a new set of attributes or completely fill inevery existing attribute, the object size grows. These additions affect the disk space, processor, andmemory 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 8.8 takes advantage ofmultiple processors. Adding processors improves performance in some areas—for example, loginsand having multiple threads active on multiple processors. eDirectory itself is not processorintensive, but it is I/O intensive.The following table illustrates typical system requirements for Novell eDirectory for Windows2000:Requirements for processors might be greater than the table indicates, depending upon additionalservices available on the computer as well as the number of authentications, reads, and writes thatthe computer is handling. Processes such as encryption and indexing can be processor intensive.2.4 Forcing the Backlink Process to RunBecause the internal eDirectory identifiers change when upgrading to eDirectory, the backlinkprocess must update backlinked objects for them to be consistent.Backlinks keep track of external references to objects on other servers. For each external referenceon a server, the backlink process ensures that the real object exists in the correct location and verifiesall backlink attributes on the master of the replica. The backlink process occurs two hours after thedatabase is open and then every 780 minutes (13 hours). The interval is configurable from 2 minutesto 10,080 minutes (7 days).After migrating to eDirectory, we recommend that you force the backlink to run by completing thefollowing procedure. Running the backlink process is especially important on servers that do notcontain a replica.1 Click Start > Settings > Control Panel > Novell eDirectory ServicesObjects Processor Memory Hard Disk10,000 Pentium III 450-700 MHz (single) 384 MB 144 MB1 million Pentium III 450-700 MHz (dual) 2 GB 1.5 GB10 million Pentium III 450-700 MHz (2 to 4) 2+ GB 15 GB
