Use the guidelines in this section to design your Novell
The success of your business continuity cluster depends on the stability and robustness of the
individual peer clusters. BCC cannot overcome weaknesses in a poorly designed cluster
environment.

3.1 Determining Design Criteria

The design goal for your business continuity cluster is to ensure that your critical data and services
can continue in the event of a disaster. Design the infrastructure based on your business needs.
Determine your design criteria by asking and answering the following questions:
What are the key services that drive your business?
Where are your major business sites, and how many are there?
What services are essential for business continuance?
What is the cost of down time for the essential services?
Based on their mission-critical nature and cost of down time, what services are the highest
priority for business continuance?
Where are the highest-priority services currently located?
Where should the highest-priority services be located for business continuance?
What data must be replicated to support the highest-priority services?
How much data is involved, and how important is it?

3.2 Best Practices

The following practices help you avoid potential problems with your BCC:
IP address changes should always be made on the Protocols page of the iManager cluster plug-
in, not in load and unload scripts.
This is the only way to change the IP address on the virtual NCP
eDirectory .
