Network Problems and Clustering

Understanding the distributed architecture and the known issues help you to work properly in an environment with several connected servers.

Vocera clustering provides a distributed architecture that allows you to locate nodes anywhere on your network, including on different subnets and in different geographic locations. This flexibility is intended in part to provide disaster recovery capabilities from catastrophic events such as an earthquake or a WAN failure.

The flexibility of this distributed cluster architecture requires you to have a stable network environment. In particular, either of the following network problems will cause unwanted cluster behavior:

Either of the network problems described above may result in the following cluster behavior:
