Preventing Network Partitions

This section provides a short list of things you can do to prevent a network partition from occurring.

To avoid a network partition:

Use NIC teaming for redundant connectivity. See http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/vmware/VMware.html#wp696452 for more information.
It is best if all servers share a common network switch. Having multiple network switches increases the possibility of a network partition occurring. If multiple switches must be used, redundant routing paths should be available, if possible. The weight of members sharing a switch in a multi-switch configuration will determine which partition survives if there is an inter-switch failure.
In terms of Geode configuration, consider the weighting of members. For example, you could assign important processes a higher weight.
