Ceph Developer Summit 2014 - Hammer

The Ceph Developer Summit (CDS) for the next major Ceph release called Hammer started today some hours ago (2014/10/28). It's again a virtual summit via video conference calls.

I've submitted three blueprints:

We already discussed the Ceph security and enterprise topics. You can find the results/logs in the pad. The sessions are recorded and will be available afterwards.

If you are interested in Ceph development: now it's time to join the video conference call. You can find all links, the timetable and blueprints to discuss here. There will be a second track with a lot of interesting discussions tomorrow.

If you are interested to work e.g. on the Ceph security topic: check the pad and feel free to contact me.

Update: OpenStack Summit Paris 2014 - CFS

An update on my talk submission for the OpenStack summit this year in Paris: my speech about Ceph performance analysis was not chosen by the committee for the official agenda. 

But at least one piece of good news: Marc's talk will be part of the OpenStack QA track.

OpenStack Summit Paris 2014 - CFS

The Call for Speakers period for the OpenStack Summit from 03. - 07.11.2014 in Paris ended this week. Now the voting for the submitted talks started and ends at 11:59pm CDT on August 6. (6:59 am CEST on 7. August).

I've submitted a talk to the storage track. The title is "Ceph Performance Analysis on Live OpenStack Platform". If you are interested to see my talk in Paris, I would appreciate if you would vote for the talk here. You can find there also the abstract of the talk.

Two of my colleagues submitted also interesting talks. Marc Koderer submitted "OpenStack QA in a nutshell" and Stefan Heuser submitted "Telekom Deutschlands Approach to NFV" to the "Telco Strategies" track.

rbd ioengine for fio

Since running benchmarks against Ceph was a topic in the "Best Practices with Ceph as Distributed, Intelligent, Unified Cloud Storage (Dieter Kasper, Fujitsu)" talk on the Ceph day in Frankfurt today, I would like to point you to a blog post about the outcome of the time we spend on benchmarking Ceph performance to find bottlenecks at the Platform Engineering team for the Business Marketplace at Deutsche Telekom AG: "Ceph Performance Analysis: fio and RBD"

Short summary: We contributed a rbd engine swiss-knife-IO-tool fio. You are now able to run tests directly against the userspace librbd implementation as e.g. used by RBD QEMU driver. This allows you to have one single IO benchmark tool to run against RBD kernel, the userspace implementation or against a RBD block device directly in your VM.

Ceph Day 2014 in Frankfurt

Back again on my blog ... as you may know I work since a while now on the topic of Cloud Storage and especially on Ceph. I didn't add new posts about this topic since a long time, but I plan to do so.

Today (2014-02-27) I'm in Frankfurt/M (Germany) to attend to the Ceph day.

There are several interesting talks/presentations on the agenda like "Best Practices with Ceph as Distributed, Intelligent, Unified Cloud Storage (Dieter Kasper, Fujitsu)" or "Ceph Performance & Optimization" (since I worked on this topic the last few months, I would like to see how others handled this challenge). I'm looking forward to meet again some of the Inktank guys I've worked with so far, some of my former SUSE colleagues and may some other Ceph community members.
