Resource requirements for integration test cluster

Hello, we're currently investigating to set up a Teuthology cluster to run the Ceph integration test suite on IBM Z, to improve test coverage on our platform. However, we're not sure what hardware resources are required to do so. The target configuration should be large enough to comfortably support running an instance of the full Ceph integration tests. Is there some data available from your experience with such installations on how large this cluster needs to be then? In particular, what number of nodes, #cpus and memory per node, number (type/size) of disks that should be attached? Thanks for any data / estimates you can provide! Bye, Ulrich
