A server pool consists of back-end server members. After you create a server pool, you associate a service monitor with the pool to manage and share the back-end servers flexibly and efficiently.

About this task

The following considerations explain the design of the server pools configuration.

  • The configuration uses NONE as a health monitor for all server pools. Until vRealize Automation is fully installed and started, the health monitor marks pool members as offline. Health monitors indicate the status of pool members correctly, only after vRealize Automaton is fully installed and initialized.

  • The configuration disables the second pool member of three vRealize Automation VIPs (vra-svr-443, vra-iaas-web-443, vra-iaas-mgr-443). During the installation or power cycle of vRealize Automation, the service inside the second node might not be installed or initialized yet. In this period, if the load balancer passes a request to the second node, the request fails. If the second pool member is not disabled, you can experience random failures during a vRealize Automation installation, and service initialization or registration failure during a vRealize Automation power cycle.

Perform the procedure multiple times to configure five different server pools.
