iQ.Clustering
IQ.CLUSTERING - BENEFITS AND FIELDS OF APPLICATION •
7.1 Benefits and Fields of Application
iQ.Clustering is an iQ.Suite feature that is activated on a Domino server after
having been installed and licensed.
iQ.Clustering provides:
• High availability
• Fail-safety
• Load Balancing
• Distributed Computing
All of these features are described in detail in this chapter.
To
If
A cluster managed by iQ.Clustering may comprise several Domino servers (reasonably
not more than 4 to 6) with iQ.Suite installed. iQ.Clustering is an application
cluster; it does not replace but complements the function of a Domino cluster.
work correctly, iQ.Clustering requires a replicated configuration on all servers
involved. The network connection between clustered servers must provide sufficiently
high data transfer rates, e.g. such as provided by LAN connections.
running iQ.Mastering (Generic Mastering), iQ.Clustering is not possible!
7.1.1 High-Availability and Fail-Safety
iQ.Clustering can be used to optimize the iQ.Suite system availability according
to the requirements of major installations or specific applications.
The servers involved under iQ.Clustering monitor each other, in particular the
email traffic in each mail.box, as well as the processing actions taken by iQ.Suite.
Should iQ.Suite be unavailable on one server (e.g. for maintenance reasons), the
other servers in the iQ.Suite cluster take over the tasks of that server.
