By  Björn Kolbeck  on  

Just like you, I don’t like the title of this post, but you the people have voted with your searches on Google. So let’s start with the commonalities: Both Ceph and Quobyte have their roots in academic research projects that started around the year 2006.

Machine Learning in the Enterprise Requires the Right Storage

By  Björn Kolbeck  on  

While Artificial Intelligence and Machine Learning have become the buzziest of buzz words over the past year or so, I was using Machine Learning for protein-folding prediction and drug design as a research student 15 years ago. Back then you needed a compute cluster or, better yet, a vector machine to train complex neural networks […] READ MORE

Checksums in Storage Systems and Why You Should Care

By  Björn Kolbeck  on  

Random bit flips are far more common than most people, even IT professionals, think. Surprisingly, the problem isn’t widely discussed, even though it is silently causing data corruption that can directly impact our jobs, our businesses, and our security. It’s really scary knowing that such corruptions are happening in the memory of our computers and […] READ MORE

Hollywood’s drive towards higher resolution video formats shows no signs of easing. Even while home users barely scratch the surface of 4K viewing, digital content creators already explore 5K and 8K variants, searching for ever more photo-realistic renditions. Along with these higher resolutions, wider color gamuts and 10 or 12-bit color depths are further driving […] READ MORE

What’s Erasure Coding and When to use it in Production

By  Felix Hupfeld  on  

When I talk to people about erasure coding, I often feel that, even though they have it on their radar, they are often uncertain about what exactly it is and how it works. Some topics in distributed storage are quite complicated and require thorough studying in order to understand them (like Paxos). Erasure coding isn’t […] READ MORE

How to Make OpenStack Continuous Integration Less of a Hassle

By  Silvan Kaiser  on  

This is a quick introduction to sos-ci (sort-of-simple continuous-integration), a lightweight alternative to the common OpenStack third party continuous integration (CI) tools that are provided by the OpenStack Infrastructure team. John Griffith created sos-ci with the intention to simplify the implementation of third-party CIs for OpenStack. If you’re planning to set up or change your […] READ MORE
