Sydney OpenStack Summit - Started

Today the OpenStack Summit started in Sydney with the keynotes. This time the keynotes are only on the first day, which is really nice since it's only a 3 days event - more time for the presentations.

This time I have every day a presentation or panel discussion:

OpenStack Sydney: Turning one into two

Last week I started to update/prepare the slides for my Lightning Talk ("Vanilla vs OpenStack Distributions - Update on Distinctions, Status, and Statistics") at the OpenStack Summit in Sydney (November 6-8, 2017). But then  I have been asked by the Summit Speaker Support to present on the same topic also in a 40 min slot. No problem, but I didn't like to speak twice about the same. I asked to use the Lighning Talk for another topic on Ceph: "Email Storage with Ceph". 

Since they accepted, I will speak in two sessions on different topics. If you are interested, check the schedule. See you in Sydney!

SUSECON - librmb slides

Presented some minutes ago at the SUSECON in Prague again on the librmb project. It seems it was the first Ceph talk today and the room was full. You can find the slides from my talk at github, they slightly changed compared to the Ceph Meetup slides.

SUSECON - librmb

I will be next week at the SUSECON in Prague to present about the new librmb/rbox project sponsored by Deutsche Telekom. The presentation slot is Tuesday, Sep 26, 1:30 PM - 2:30 PM. If you attend and are interested on how to store emails directly in Ceph RADOS add the session to your schedule.

Ceph Meetup Berlin - Followup: librmb

On Monday I presented at the Ceph Meetup in Berlin about a new project sponsored by Deutsche Telekom to store emails on Ceph. The project consists of librmb and rbox. While librmb (librados mailbox) is a generic abstraction layer to store emails in RADOS, rbox is a plugin for Dovecot to make use of the new library.

The code is released under LGPLv2.1 and now available at github. The project is still under heavy development and not in a released state. Therefore the code and APIs can still change, but we really would like to invite every interested party to check it out, test the code and report findings and bugs back to the project. Be part of the project and contribute code! We plan to move the librmb code later to the Ceph project and the rbox plugin to Dovecot. For more information on the project check out the README or take a look at my presentation from the Meetup.

I would like to thank our partners in this project: Tallence, Wido den Hollander (42on.com), and SUSE.

Ceph Meetup Berlin

I will give a presentation at the next Ceph Meetup in Berlin on the 18th of September. It will be about a exciting project we work on, at Deutsche Telekom, since a while. The goal of this open source project called librmb is to store emails directly in Ceph RADOS instead of using e.g. a NAS system. 

For an short abstract checkout out the Meetup description. The Meetup is already full, but there is a waiting list you can subscribe to. The slides from the talk will be available afterwards if you are not able to join. Otherwise see you in Berlin.

OpenStack Summit Sydney: Vote for Presentations

The next OpenStack Summit takes place in Sydney (Australia), November 6-8, 2017. The "Vote for Presentations" period will end in less than a day. All proposals are still up for community votes. The deadline for your vote is will end August 3th at 11:59pm PDT (August 4th at 8:59am CEST).

I have submitted this time one proposal:

  • Vanilla vs OpenStack Distributions - Update on Distinctions, Status, and Statistics One year ago in Barcelona we have taken a look behind the curtain of OpenStack Vanilla and the products of the four major OpenStack distributions. Let’s have an update and deeper look into it. You have the agony of choice if it comes to the question: Vanilla or an OpenStack distribution. It will highly depend on your usecase, technical requirements, resources and organization. This presentation will not only highlight differences between these choices but also between the distributions and their offerings. There is more to take a look at than only the OpenStack product itself as e.g. different hypervisor, Ceph, the base distributions and support. This time we also include new topics like SDN, NFV, Container and Managed Cloud. And for sure we will have a lot of new and updated statistics on community contribution and market share. This talk will cover besides Vanilla also at least RedHat, SUSE, Ubuntu/Canonical, and Mirantis OpenStack.
As always: every vote is highly welcome! And don't forget to search for other interesting proposals around Ceph, NFV and OpenStack as e.g. the presentations from Florian Haas [1][2][3].

opendev: OpenStack Foundation failed to learn the lesson

Yesterday I got an invitation to the opendev conference (September 7-8, 2017) from the OpenStack foundation. The conference is about edge computing. 

While the topic itself is very interesting I was surprised that the opendev will be held in the U.S. (San Francisco, CA). I thought the foundation would have learned a lesson from the Boston summit this year. And as far as I understood it they decided to have currently no summits in the U.S. anymore until the political climate changed to allow risk free travel for all community members (see Kurt Garloff's talk at DOST around 8:45min). But it seems this applies only to the summits, very inconsistent! Some people would call it slightly duplicitous.

In light of the OpenStack Foundation's decision I'm still proud about the Ceph community. They decided with a clear statement to not held any event in the U.S. that requires travel for community members from foreign countries while there is the risk to potentially suffer harassment, digital privacy violations, or rejection at the border.

Reminder: OpenStack Summit Sydney - CFP Deadline

A short reminder: the "Call for Presentations" deadline for  the next OpenStack Summit in Sydney, Australia (November 6-8, 2017) is less an a day away. 
If you would like to present in Sydney submit your proposal till July 14, 2017 at 11:59pm PDT (July 15, 2017 at 6:59am UTC).

Sunday, May 14, 2017


I already submitted to talks for the Cephalocon 2017 in Boston end of August this year but unfortunately - for the community - the conference was cancelled on Friday this week.

Here a quote from the cancellation statement:
The Ceph community has always been based on the principles of openness, inclusion, and a level playing field for all participants. We have worked hard to ensure that no matter what time zone you’re in, who you are, or how technically knowledgeable you are there is always a way for you to participate and contribute to the Ceph community.

It is our sincere hope that the people of the United States will course-correct their leadership to conform to the principles that the country was founded on, and has served so well throughout history. In the meantime, we wont be hosting any events that require members of our community to travel to the U.S. and potentially suffer harassment, digital privacy violations, or rejection at the border.
For the full statement please check this page

Though these are `SAD` news for the community, I fully support the decision and the statement. I'm looking forward for a new date for a Cephalocon, propably in Canada, Mexico or around the next OpenStack Summit in Sydney end of this year. It would be really good if the full Ceph community - including the developers - could get together at least once in a while.

OpenStack Summit Boston: Vote for Presentations

The next OpenStack Summit takes place in Boston, MA (USA) in May (8.-11.05.2017). The "Vote for Presentations" period started already. All proposals are now again up for community votes. The period will end February 21th at 11:59pm PST (February 22th at 8:59am CEST).

This time I have submitted a proposal together with WDLabs:

  • Next Generation Hardware for Software Defined Storage - Software Defined Storage like Ceph has changed the storage market dramatically in the last few years. While software has changed, storage hardware stayed basically the same: commodity servers connected to JBODs utilizing SAS/SATA devices. The next step must be a revolution in the hardware too. At the Austin summit the Ceph community presented a 4 PB Ceph cluster comprised of WDLabs Converged Microservers. Each Microserver is built by starting with an HGST HE8 HDD platform and adding an ARM and DDR running Linux on the drives itself. WDLabs provided access to early production devices for key customers such as Deutsche Telekom for adoption and feedback. This talk will provide insight into our findings running a Ceph cluster on this platform as a storage provider to OpenStack.
This period the voting process changed again unique URLs to proposals seems to work again. So if you would like to vote for my talk use this link or search for the proposal (e.g. use the title from above or search for "Al-Gaaf"). As always: every vote is highly welcome! 

As the last times I highly recommend to search also for "Ceph" or what ever topic your are interested in. You find the voting page here with all proposals and abstracts. I'm looking forward to see if and which of these talks will be selected.
