NDS Tree Design NetWare
Formerly TIDS 2919741 2938313
Below are some current GENERAL NDS Design Guidelines that Consulting and Technical Support agreed upon. Please note these are merely guidelines, and intended as FYI only.
Customers needing advanced diagnosis and tree design should Contact Novell Consulting who can engineer a design that meets specific needs. There are many other factors not mentioned that can effect tree design.
General NDS Design Guidelines are:
1. Design top of tree based on WAN infrastructure
2. Design bottom of the tree based on organization of the network resources
3. No global groups
1. Partition top of the tree based on the WAN infrastructure
2. Do NOT create a partition that spans the WAN (split across a WAN link)
3. Partition around the local servers in each geographic area
4. Partition top of the tree based on size (1000 - 1500 objects). This is not true for NDS v8, the maximum recommended partition size for v8 is 100,000's of users.
1. Maintain three (3) replicas for fault tolerance
2. Replicate locally (if possible)
3. Replicate to provide bindery service access
4. Place a Master replica at hub sites not remote sites.
Specific NDS Design Numbers:
QUICK DESIGN (Always works well)
Partition size: 1000 - 1500 objects (v8 100,000's)
Number of Child partitions per parent: 10 - 15 partitions
Number of replicas per partition: 2 - 5 replicas (typically 3)
Number of replicas per server: 7 - 10 replicas
MINIMUM server hardware: 486/66 Mhz with 32 MB of RAM (NW 4.2 Only)
ADVANCED DESIGN (requires advanced technical knowledge and DS tool knowledge)
Partition size: 3500 - 5000 objects (v8 100,000's)
Number of Child partitions per parent: 35 - 40 partitions
Number of replicas per partition: 10 replicas (typically 3)
Number of replicas per server: 20 replicas
MINIMUM server hardware: Pentium 100+ Mhz with 64 MB of RAM (NW 4.2 Only)
