Sue Unix Event - 27 & 28 maart 2014


Eind maart organiseerden wij het Sue Unix Event (SUE 2014). De twee dagen met vrijwel identieke programma's werden zeer goed bezocht. Technische sprekers uit binnen- en buitenland hebben de deelnemers de hele dag weten te boeien. In de middag gaf Mark Burgess een intensieve workshop CFengine.

Mark Burgess

The Collapse of Complex Infrastructures


Mark is CTO and founder at CFengine and was professor at Oslo University in Norway, he is well known for his work in computer science in the field of policy-based configuration management.


Consumer IT services continue to grow in scope and variety, and the infrastructure for bringing them to life is exploding in scale, speed, and complexity. History shows that all collaborative systems eventually fail because of the law of "diminishing marginal returns". What does this mean in IT, and how do we ensure that technology scales to meet society┬┤s needs with a minimum of overhead? What does it mean for competitive advantage, for agilty, quality and time to market? In this talk, Mark Burgess explores more of the ideas from his latest book In Search of Certainty: The science of our information infrastructure, and explains how we can cope with necessary and sufficient complexity.

John D Cook

Erasure coding costs and benefits


One way to describe what John does is very applied math, using math to solve real-world problems, often in combination with computing, consulting, managing, marketing, etc. His primary occupation is consulting. He has consulted for clients in diverse sectors including semiconductors, pharmaceuticals, medical devices, software, law, and government. He also taught mathematics at The University of Texas at Austin and Vanderbilt University and taught statistics at the UT Graduate School of Biomedical Sciences.


In order to build highly reliable systems out of less reliable parts, systems introduce redundancy. In replicated systems, objects are simply copied several times with each copy residing on a different physical device. While such an approach is simple and direct, more elaborate approaches such as erasure coding can achieve equivalent levels of data protection using less redundancy. This talk explores the trade-offs in cost and performance between replicated and erasure encoded storage systems.

Martijn Posthuma

Hypervisor as a storage node


Martijn is a consultant with Sue B.V. since 2008 and recently certified as one of Sue 5 RHCA's (RedHat Certified Architects).

Harald van Breederode

Oracle Database Smart Flash Cache


Harald is a Senior Principal DBA Instructor at Oracle with over 30 years computer industry experience. He started his career at Oracle over 20 years ago as a Unix Systems administrator. The past 15 years he has been sharing his knowledge of Oracle Technology in the classroom as an instructor at Oracle University.
Harald presents courses and seminars on UNIX (Oracle Linux, Oracle Solaris), SQL Tuning and Database Tuning, Database Administration, High Availability (CRS, ASM, RAC and Data Guard) and the Oracle Exadata Database Machine. He is the Technical Team Leader for the Oracle Linux and Oracle Solaris Certification Exam development team and a Consulting Architect to the Oracle Database Certified Master Exam development team.
Harald is a member of the "Oak Table" Network of Oracle Database Professionals, an Oracle Database 8i to 12c Administrator Certified Professional and an Oracle Database 10g and 11g Administrator Certified Master.


This presentation introduces you to Oracle's Database Smart Flash Cache. This database feature was introduced in Oracle11g Release 2, is easy to implement and monitor. It has the potential to offer considerable benefit to users of Oracle Database 11g Release 2 and Oracle Database 12c with disk-bound read-mostly or read-only workloads.
The presentation starts with an architectural overview, followed by an explanation of relevant database parameters, wait events and database statistics used to administer and monitor the feature. Harald will describe the circumstances in which Database Smart Cache is beneficial and he will share results from implementations at Oracle customer data centers. The presentation concludes with a live demo.

Jelmer Vernooij

Samba4 heads-up


Jelmer is a member of the global Samba Team, a loose-knit group of about 20 people who contribute regularly to Samba. Together with John H. Terpstra, he is editor of the `The Official Samba-3 HOWTO and Reference Guide', published by Prentice Hall.
Jelmer has been using free and open source software since 1997 and has contributed to various open source projects, including Samba, OpenChange, Wireshark, Debian and Ubuntu.


The Samba project provides a free software implementation of the SMB/CIFS protocol and related protocols for POSIX-compatible systems. Most people have come across these protocols as the "File and printer sharing" option in Microsoft Windows.
After 10 years, we released version 4.0 of Samba last year. This is the first version that adds support for being a domain controller in an Active Directory domain. I'll talk about why Active Directory is so hard, what is new in Samba 4.0 and where we are headed next.

Ronny Lam

Software Defined DataCenter, SDN & NFV


Ronny started his career in networking some 20 years ago and joined Sue B.V. not much later. He developed a networking team within Sue and did consulting for the large Dutch Cable Operators. Provisioning of networks has always been his main focus and that's why he joined NetYCE a couple of years ago. Ronny embraced the recent rise of DevOps and Software Defined Networking, which started the so much needed (r)evolution of the network.


To explain the concept of the Software Defined DataCenter we have to dissect it's definition. What is this Software Defined thing we hear everywhere? Why Software Defined Networking was the last hurdle to the SDDC and what it has to do with Network Functions Virtualization. This presentation is providing an overview of these concepts from a networking perspective. What are current technologies and what we can expect for the future.


Deze intensieve workshop CFengine werd gegeven door Mark Burgess.
