Wir sagen Danke!

Wir sagen Danke an alle unsere Sponsoren, ohne die die professionelle Durchführung der OSMC nicht möglich wäre.
Dieses Jahr bedanken wir uns besonders bei der Thomas Krenn AG, dem Admin Magazine, sowie dem Linux Magazin. Spezieller Dank gilt außerdem der Firma GroundWork aus den USA, die Software zur Überwachung von Servern, Netzwerken, etc. zur Verfügung stellen.
Wir würden uns sehr freuen, euch auch im nächsten Jahr wieder Sponsoren der OSMC nennen dürfen!
Save the date: 21.-24. November 2017 in Nürnberg!

OSDC 2016 – Thank you all and see you again on May 16 to 18, 2017 in Berlin!

osdc_overview_2016_thanks_center_165x185Once again the Open Source Data Center Conference has been a superb success! A big thank you goes to our participants and speakers for three days of hands-on workshops, expert lectures, in-depth discussions, knowledge exchange, social networking and community building. We hope you all had a great time and enjoyed the event as much as we did.
 
 
 
We would also like to thank our loyal supporters Thomas Krenn, Linux Magazin and ADMIN Magazine for their fabulous support!
We hope to see you all again next year in Berlin! SAVE THE DATE: May 16 to 18, 2017

Guest Post by Alan Robertson: How The Assimilation Project Got Started

Back in about 2010, I was working on a highly custom supercomputer research project with about 2.2 million cores called Cyclops64. It was a joint project between the University of Delaware, IBM and the NSA. It was interesting in a lot of respects, but what its most unusual feature was its networking. Each system was directly connected to 6 other systems by high-speed interconnects forming a cube, and only a few systems on one of the cube faces were connected to a “normal” ethernet network. The cube was 24x24x24 and each system had 160 cores (total: 2211840 cores).
As I thought about it, I realized that the way conventional monitoring systems like Nagios or Icinga work would be absolutely horrible in this environment. Imagine that the monitoring system was in one corner of the cube. Then each “Are You OK?” message would have to through 24 systems up, then 24 systems to the right, then 24 systems forward. The return message would have to follow the reverse return path – meaning that each round trip would touch 144 systems. Of course, the network in the vicinity of the central system would be totally destroyed by this traffic if it happened at any reasonable rate.
After thinking about it, I realized that it would be much better if each system monitored its six neighbors instead – delegating these “Are You OK?” queries to the machines being monitored. This totally changed the complexity of the task, and the network load – no network hot spots, and the central system had nothing to do most of the time – an amazing difference! I also realized that more conventional systems have these same problems of network congestion and ever growing centralized workload.
So, I adapted this idea to “normal” systems, and the Assimilation Project was born – providing greater scalability than any predecessors, while being incredibly simple. To keep the same topology-awareness that the original idea had, I realized that I needed to discover network connectivity. Once I’d done that, I realized that I could easily discover what services the system had which would eliminate manual configuration. Further, I could discover dependencies, which are essential to tracing problems to their root causes. Then I realized that this was all really a huge graph, so I adopted the Neo4j graph database. Lots of other valuable capabilities quickly became obvious results of having comprehensive and scalable discovery.

So, it goes without saying that I’m excited to return to the OSMC in Nürnberg and talk about all the exciting new things we’re doing in the Assimilation Project. After all, the last time I was there, I had a great time and my talk got some pretty cool tweets.

OSDC 2015: Thank you and see you again!

This year’s Open Source Data Center Conference has been a big success! With about
170 attendees from 12 countries we had one of the biggest and most international conferences so far.
We like to thank our sponsoring partners for their support!
Thomas Krenn and Linux Magazin are backing us and our conferences from the very beginning on and were of course part of this year’s OSDC   again.
Linux und TK-Kombi
 
 
We hope you all took the chance to visit Thomas Krenn at their booth and read a lot of issues of LINUX Magazin.
We are also very proud to welcome Attingo Data Rescue and ADMIN Magazine as two new partners and are looking forward to work with them again at future events.
Attingo und ADMIN Kombi
Maybe you already visited Attingo at their booth at the conference or read one of the ADMIN Magazines we distributed.
And of course we like to thank our speakers and attendees! It has been a pleasure to welcome you at the event! We hope to see you again at OSDC 2016!
