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.
