Tuning for Zero Packet Loss in Red Hat OpenStack Platform – Part 1

For Telcos considering OpenStack, one of the major areas of focus can be around network performance. While the performance discussion may often begin with talk of throughput numbers expressed in Million-packets-per-second (Mpps) values across Gigabit-per-second (Gbps) hardware, it really is only the tip of the performance iceberg. The most common requirement is to have absolutely stable and deterministic network performance (Mpps and latency) over the absolutely fastest possible throughput. With that in mind, many applications in the Telco space require low latency that can only tolerate zero packet loss.

In this “Operationalizing OpenStack” blogpost Federico Iezzi, EMEA Cloud Architect with Red Hat, discusses some of the real-world deep tuning and process required to make zero packet loss a reality!

Using Ansible Validations With Red Hat OpenStack Platform – Part 3

In the previous two blogposts (Part 1 and Part 2) we demonstrated how to create a dynamic Ansible inventory file for a running OpenStack cloud. We then used that inventory to run Ansible-based validations with the ansible-playbook command from the CLI.

In the final part of our series, we demonstrate how to run those same validations using two new methods: the OpenStack scheduling service, Mistral, and the Red Hat OpenStack director UI.
