fio-iperf3

Dockerfile

Used to build a ubi8 container with fio and iperf3 installed

ss-fio-iperf3

Used to deploy an OpenShift statefulset that instantiate one pod per compute node.

The pod will request an 3GiB RBD PVC and a 3GiB CephFS PVC. The PVCs will be mounted in /mnt/rbd and /mnt/cephfs respectively. All fio test should be run based on one of those mountpoints.
