This is a very simple post to show the results of some recent testing that Tom and I ran using Oracle SLOB on Violin to determine the impact of using virtualization. But before we get to that, I am duty bound to write a paragraph of text featuring lots of long sentences peppered with industry buzz … Continue reading The Great Hypervisor Bake-off: VMware ESX vs Oracle VM

Predictions for 2014: DataBase-as-a-Service
It's that time of year again where lots of people write articles which begin with the words "It's that time of year again..." and make endless references to crystal balls, tea leaves and the benefits of hindsight. But not me, I'm not descending into cliché. Apart from that first sentence, which with the benefit of … Continue reading Predictions for 2014: DataBase-as-a-Service
Engineered Systems – An Alternative View
Have you seen the press recently? Or passed through an airport and seen the massive billboards advertising IT companies? I have - and I've learnt something from them: Engineered Systems are the best thing ever. I also know this because I read it on the Oracle website... and on the IBM website, although IBM likes … Continue reading Engineered Systems – An Alternative View
Database Workload Theory
In the scientific world, theoretical physicists postulate theories and ideas, for example the Higgs Boson. After this, experimental physicists design and implement experiments, such as the Large Hadron Collider, to prove or disprove these theories. In this post I'm going to try and do the same thing with databases, except on a smaller budget, with less … Continue reading Database Workload Theory
Database Virtualisation: The End of Oracle RAC?
A long time ago (2003) in a galaxy far, far away (Denmark), a man wrote a white paper. However, this wasn't an ordinary man - it was Mogens Nørgaard, OakTable founder, CEO of Miracle A/S and previously the head of RDBMS Support and then Premium Services at Oracle Support in Denmark. It's fair to say that … Continue reading Database Virtualisation: The End of Oracle RAC?
Exadata Roadmap Preview
Last week, Andrew Mendelsohn gave a talk at the Enkitec Extreme Exadata Expo ("E4") run in Texas by those excellent guys at Enkitec. Andrew is the SVP of Oracle's Database Server Technologies group, so it's fair to say he has his finger on the pulse of the Oracle roadmap for Exadata. Big thanks to Frits Hoogland … Continue reading Exadata Roadmap Preview
Database Virtualization Part 2 – Flash Makes The Difference
In part one of this article I talked about Database Virtualisation and how I believe that it is the next trend in our industry. Databases - particularly Oracle databases - have held out against the rise of virtualisation for a long time, but as virtualisation products have matured and the drive to consumerise and consolidate … Continue reading Database Virtualization Part 2 – Flash Makes The Difference
Database Virtualization Part 1 – It’s Happening Right Now
Forget Big Data. Stop talking about Analytics. There is a trend taking place in the marketplace right now, one that is really happening rather than just being spoken about. That trend is Database Virtualisation. Or, as my U.S. cousins would spell it, Database Virtualization. (And whilst I am loath to drop the Queen's English in … Continue reading Database Virtualization Part 1 – It’s Happening Right Now
Database Consolidation Part 4 – Flash Memory Makes The Difference
[This is part four of a series of articles about database consolidation. Part one addressed the business drivers and technical challenges, with part two focussing on design choices. Part three was about capacity planning and the concept of overcommitting resources. This section will now look at each resource and see how flash memory helps achieve … Continue reading Database Consolidation Part 4 – Flash Memory Makes The Difference
Database Consolidation Part 3 – It’s All About Capacity
In parts one and two of this article I blogged, extensively and laboriously, about database consolidation. I talked (at length) about the business drivers for this industry trend, then went on to discuss (for some considerable time) the technical challenges. I even droned on about the different design choices faced by enterprises who are about to embark … Continue reading Database Consolidation Part 3 – It’s All About Capacity
