Using Red Hat OpenStack Platform director to deploy co-located Ceph storage – Part Two

Previously we learned all about the benefits in placing Ceph storage services directly on compute nodes in a co-located fashion. This time, we dive deep into the deployment templates to see how an actual deployment comes together and then test the results!

Enabling Co-Location

This article assumes the director is installed and configured with nodes already registered. The default Heat deployment templates ship an environment file for enabling Pure HCI. This environment file is:

/usr/share/openstack-tripleo-heat-templates/environments/hyperconverged-ceph.yaml

Using Red Hat OpenStack Platform director to deploy co-located Ceph storage – Part One

An exciting new feature in Red Hat OpenStack Platform 11 is full Red Hat OpenStack Platform director support for deploying Red Hat Ceph storage directly on your overcloud compute nodes. Often called hyperconverged, or HCI (for Hyperconverged Infrastructure), this deployment model places the Red Hat Ceph Storage Object Storage Daemons (OSDs) and storage pools directly on the compute nodes.

Co-locating Red Hat Ceph Storage in this way can significantly reduce both the physical and financial footprint of your deployment without requiring any compromise on storage.

OpenStack Summit Sydney preview: Red Hat to present at more than 40 sessions

The next OpenStack Summit will take place in Sydney, Australia, November 6-8. And despite the fact that the conference will only run three days instead of the usual four, there will be plenty of opportunities to learn about OpenStack from Red Hat’s thought leaders.

Red Hatters will be presenting or co-presenting at more than 40 breakout sessions, sponsored track sessions, lightning talks, demos, and panel discussions. Just about every OpenStack topic, from various services to NFV solutions to day-2 management to containers integration will be covered.

Tuning for Zero Packet Loss in Red Hat OpenStack Platform – Part 3

In Part 1 of this series Federico Iezzi, EMEA Cloud Architect with Red Hat covered the architecture and planning requirements to begin the journey into achieving zero packet loss in Red Hat OpenStack Platform 10 for NFV deployments. In Part 2 he went into the details around the specific tuning and parameters required. Now, in Part 3, Federico concludes the series with an example of how all this planning and tuning comes together!

Tuning for Zero Packet Loss in Red Hat OpenStack Platform – Part 2

Ready for more Fast Packets?!

In Part 1 we reviewed the fundamentals of achieving zero packet loss, covering the concepts behind the process. In his next instalment Federico Iezzi, EMEA Cloud Architect with Red Hat continues his series diving deep into the details behind the tuning.

Buckle in and join the fast lane of packet processing!

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!

OpenStack Down Under – OpenStack Days Australia 2017

As OpenStack continues to grow and thrive around the world the OpenStack Foundation continues to bring OpenStack events to all corners of the globe. From community run meetups to more high-profile events like the larger Summits there is probably an OpenStack event going on somewhere near you.

One of the increasingly popular events is the OpenStack Days series. OpenStack Days are regionally focussed events sponsored by local user groups and businesses in the OpenStack universe. The are intended to be formal events with a detailed structure, keynotes and sponsorship.

This year’s OpenStack Days – Australia was held June 1st in Melbourne, Australia and Red Hat was proud to be a sponsor with speakers in multiple tracks!

Back to Boston! A recap of the 2017 OpenStack Summit

This year the OpenStack® Summit returned to Boston, Massachusetts. The Summit was held the week after the annual Red Hat® Summit, which was also held in Boston. The combination of the two events, back to back, made for an intense, exciting and extremely busy few weeks.

More than 5,000 attendees and 1,000 companies were in attendance for OpenStack Summit. Visitors came from over 60 countries and could choose from more than 750 sessions.

And of course all sessions and keynotes are now easily accessible for online viewing at your own leisure.

The Summit proved to be a joyful information overload and I’d like to share with you some of my personal favorite moments.

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.

Using Ansible Validations With Red Hat OpenStack Platform – Part 2

In Part 1 we demonstrated how to set up a Red Hat OpenStack Ansible environment by creating a dynamic Ansible inventory file (check it out if you’ve not read it yet!).

Next, in Part 2 we demonstrate how to use that dynamic inventory with included, pre-written Ansible validation playbooks from the command line.
