Manage host pools

This section describes how to manage pools of testing hosts used for running server-side functional and performance tests in ALM.

Host pools overview

A host pool is a group of testing hosts. Each project has one host pool. When managing a host pool, it is important to understand the total available resources.

If you are using the pool for a project which involves performance testing, the pool must contain at least one Controller, one load generator, and one data processor. Because hosts can have dual functionality, it is recommended that a pool contains, among the other hosts, at least one host that can be dedicated fully for Controller functionality.
