So, what makes Solaris Zones so cool?

How do you virtualize? Do you emulate virtual machines? Do you partition your servers' hardware? Or do you run a container technology? 

This post is about the third option, a container technology built right into Solaris: Solaris Zones. They are pretty awesome. But what exactly makes Zones so cool?

What is the best platform to run your Oracle Database on?

As a Systems Consultant I am often faced with the following question: What does Oracle recommend as the best platform to run the Oracle DB in large enterprise environments on? Is the Exadata DB Machine the recommended platform? Are SPARC/Solaris servers the way to go? Or should customers consolidate on SPARC SuperCluster setups? 

...at this point customers look me deep into the eyes, and ask the critical question: What does Oracle actually recommend?
The answer usually perplexes them, for I say every time: "It depends."  [Read More]

The SPARC T5 Servers have landed

At last, the SPARC T5 servers are announced! They are worthy heirs of the SPARC T-series, and even more powerful than their popular technology predecessors the SPARC T4

Before we'd go into the technical details, here is a very important message: 

Having announced the T5 servers doesn't make the T4s go away. It is not a platform replacing technology, but a platform extending one! Oracle is going to offer SPARC T4 and T5 servers side-by-side!

Having said that, let's dive headfirst into the details to soothe the techcrave: 

What's new with the SPARC T5 servers?

    Best Practices to build SAP, Tiered Storage, IaaS cloud, E-Business Suite or Siebel HW platforms? Optimized Solutions.

    Summary: 
    - Platform building resources are scarce everywhere. 
    - The most timeconsuming part is usually cherrypicking, validating, testing and integration
    - There are predefined, freely available architecture whitepapers describing tested and validated platform architectures for different tools. 
    - Using these customers spare a serious amount of implementation man-days, and can focus on providing services.

    How to build a private IaaS cloud platform? - Main Post

    I had the chance to give talks about evaluating the requirements for, and building private IaaS cloud platforms.

    Often I was explained the following situation: A corporate manager went to OpenWorld, a local Oracle Day or a Virtualization Day, and has seen everywhere that cloud platforms are the future. As a good businessman, he wants to benefit from the new wave and wants you, the system administrator/datacenter engineer/platform architecht to build an Infrastructure as a Service platform to provide virtual environments for your internal or external customers. What do you do? Allow me to point out some of the requirements and considerations.

    Clustering Basics and Challenges

    For upcoming posts it seemed to be a good idea to dedicate some time for cluster basic concepts and theory. This post misses a lot of details that would explode the articlesize, should you have questions, do not hesitate to ask them in the comments. 

    The goal here is to get some concepts straight. I can't promise to give you an overall complete definitions of cluster, cluster agent, quorum, voting, fencing, split brain condition, so the following is more of an explanation. 

    Here we go.

    This is a followup post to the previous summary on the "What's new with Solaris 11 since the launch" webcast. That webcast has had a chatroom for a live Questions and Answers session running. I went through the archive of those and compiled a list of some of the (IMHO) most relevant and most frequently asked questions, I'd like to share. This is the first part, covering the QnA of Session I and II of the webcast, in a followup post we can have a look of the rest of the sessions if required - let me know in the comments. Also, should you have questions, as usual, feel free to ask those there too. [Read More]
