This topic describes how to plan VMware GemFire topology and communication.

Create a topology plan and a detailed list of machines and communication ports that your members will use. Configure your VMware GemFire systems and the communication between systems.

Determine Protocols and Addresses

Your configuration governs how your applications find each other and distribute events and data among themselves.

Work with your system administrator to determine the protocols and addresses you will use for membership and communication.

  1. For each host machine with more than one network adapter card, decide whether to use the default address or one or more non-default bind addresses. You can use different cards for peer and server.
  2. Identify any members you want to run as standalone, isolated members with no member discovery. This can be a good option for clients, because it has faster startup but no peer-to-peer distribution of any kind.
  3. For all non-standalone members:
    • Decide how many locators you will use and where they will run. To ensure the most stable startup and availability, use multiple locators on multiple machines.
    • Create a list of your locators’ address and port pairs. You will use the list to configure your system members, any clients, and the locators themselves.

Set Up Membership and Communication

Using the protocols and addresses you determined above, do the following:
