Business Continuity Clustering

6 Feb


One problem faced by organisations when they are developing their business continuity plan is the sheer distance between various branches and headquarters. This opens a company up to a wide array of possible disruptive events. One way for companies to counter this problem is to use what is known as Business Continuity Clustering. Business Continuity Clustering allows IT administrators to cluster up to four geographically separate SAN’s to both replicate and mirror data in case of any disruptive event occurring. Each SAN acts as a fail over for each other when problems occur. “Business Continuity Clustering not only eliminates downtime, but it also automates the configuration and management of your business-continuity solution. This saves you time, minimizes the possibility of human error and reduces your total cost of ownership”.(1)  One area where this might be useful is with Colleges and Universities. Travis Berkley, manager of LAN services for the University of Kansas in Lawrence, has seen demonstrations of the clustering and replication technology. “We might use this [product] for connecting remote campuses we have for replicating important PeopleSoft data,” Berkley says. Novell were the first company to offer this service. Their product offers a Recovery Time Objective of less than 5 minutes and a 0-second Recovery Point Objective. RTO covers how long a customer can afford to be without its applications and data; RPO measures the amount of data a customer can afford to lose.(2)

Effectively, Novell Continuity Clustering is built on the Standard Cluster Service with the addition of specialised software for configuration, synchronisation and maintenance. Typically, implementation involves two distinct clusters in a cluster of clusters, In the event of disaster, selected cluster resources or all cluster resources can fail over from one cluster to another.


NBCC is capable of allowing as few as one server to failover to as many as them all. It supports up to four clusters for a total of 128 nodes working together so as to ensure a high level of service uptime. (3)

Business Continuity Clustering ultimately protects your businesses against downtime and disaster and ensures your application and network resources are working 24/7 while still being possible to perform system maintenance and upgrades. In conclusion, with BCC you have the flexibility to create a redundant system that best serves the organic nature of the network. Whether you have a single or multiple sites with application and data redundancy needed for each you can tailor BCC to your requirements so as to easily implement any business continuity plan to protect against any type of disaster.
