There is no doubt the acceptance and growing popularity of Linux on Power is here.  With POWER based systems providing advantages over x86 systems in performance, capacity, memory and IO bandwidth, and reliability (I have intentionally left out the CAPI technology and am saying that discussion for another BLOG that can delve into that and the incredible capabilities it provides)   and with the latest Linux distributions from RedHat, SUSE, and Ubuntu exploiting POWER8 technology, customers are now looking at hosting mission...

Then, in August I attempted to eliminate uncertainty in my Removing the FUD and Demystifying LE (little endian) article. With the announcement of the Red Hat Enterprise Linux 7.1 beta delivering an LE version, it is time to revisit little... [More]

by Jeff Scheel, IBM Linux on Power Chief Engineer A great blog entry floated through my email inbox this week that raised a broader discussion topic for me: folks may have heard about the OpenPOWER Foundation, but may not know where to read the latest information.  So, I thought I'd provide a few pointers. The OpenPOWER Foundation website is the starting point for all information about the foundation.  When all else fails, start there. Under the site " News/Events " link at the top of the page, you will... [More]

By: Jenifer Hopper   This article discusses some basic XML tuning tips for PowerKVM guests. It helps new users get started with editing guest XML definitions, and walks through some simple tuning examples.   The article covers various options to tune the guest disk, network, cpu, and memory. It also includes some example guest resource pinning configurations for different scenarios. Applying these tips may help improve application performance by ensuring your guest is configured properly and optimized for the KVM environment.

by Jeff Scheel, IBM Linux on Power Chief Engineer p { margin-bottom: 0.08in; }a:link { } I couldn't resist the urge to use TLAs (three letter acronyms) to dispel the FUD (fear, uncertainty, and doubt) on my favorite topic, LE (little endian). p { margin-bottom: 0.08in; }a:link { } If you are like most customers (and my mother), the concept of data endianness rarely, if ever, enters your mind. You buy applications, operating systems, and computers. All you care is that the operating systems run your applications on the computer to... [More]

by Jeff Scheel, IBM Linux on Power Chief Engineer As promised, here is my first blog post on little endian or "LE" as we call it.  Where better place to start than with a list of frequently ask questions (FAQs)?  Hopefully, you'll find this helpful.  Let me know if you have any questions I missed. What is big endian and little endian, anyway? In order to perform operations on data, computers routinely load and store bytes of data from and to memory, the network, and disk.  This data management generally follows... [More]

IBM Power Systems is putting data to work! On April 23, we introduced Power Systems built for bigger data demands in the cloud, expanding world's first Linux-based open server ecosystem. This provides you with tools tuned for a platform that boosts productivity and performance by removing constraints imposed by commodity architecture, along with accelerating compute and data-intensive tasks that improves cloud economics. While I trust that you have already gotten started building and deploying on this, I would like to throw a challenge your... [More]

At Impact 2014, Doug Balog and Mark Shuttleworth provided a glimpse of the work completed on POWER8 systems with Ubuntu 14.04 from Canonical. In a Keynote presentation available on Youtube , Mark Shuttleworth's team does a demo of deploying 8 KVM guests - starting from scratch, installing the OS on each guest, the application software, configuring, running, inter-connecting, and ready for work.    JuJu's and Charms are actually pretty slick.   Something good to learn in the coming days. On the Youtube video, fast forward... [More]

By: Jeff Scheel, PowerLinux Chief Engineer A software provider recently said, point blank, at the beginning of our discussion, “Convince me that PowerLinux is not a new platform.” The core of my answer went like this: the value of Linux is the same for software providers as it is for customers – Linux provides a single operating system environment across different hardware platforms. Customers and partners who have both x86 Linux skills and Power System skills have all the knowledge they need to run Linux on IBM Power Systems... [More]

If you are an IBM Business Partner or IBM employee who needed remote access to Power Systems servers in the past, you might have come across the Virtual Loaner Program (VLP). The VLP is gone now, but not to worry, it has been replaced by the Power Development Platform (PDP). In addition to the name change, the program added new features and comes with an improved web interface. As did the VLP, the PDP focuses on bringing ISVs, other Business Partners and IBM employees worldwide remote access to IBM POWER processor-based servers on the IBM AIX,... [More]
