Topology and Communication General Concepts
Before you configure your Pivotal GemFire members, make sure you understand the options for topology and communication.
The Pivotal GemFire topology options allow you to scale horizontally and vertically.
Create a topology plan and a detailed list of machines and communication ports that your members will use. Configure your Pivotal GemFire systems and the communication between systems.
Pivotal GemFire provides various options for member discovery within a distributed system and between clients and servers.
GemFire uses a combination of TCP and UDP unicast and multicast for communication between members. You can change the default behavior to optimize communication for your system.
You use a bind address configuration to send network traffic through non-default network cards and to distribute the load of network traffic for GemFire across multiple cards. If no bind address setting is found, GemFire uses the host machine’s default address.
By default, Pivotal GemFire uses Internet Protocol version 4 for GemFire address specifications. You can switch to Internet Protocol version 6 if all your machines support it. You may lose performance, so you need to understand the costs of making the switch.
