Shameless Analyst Report Plug: “IBM & Linux – 9 Years Later”
A colleague sent me a link to this analyst paper today that takes a look at whether IBM has made good on the Linux promises it made back in 1999. I’m obviously biased, but I’m interested in hearing if anyone has thoughts on this topic.
Here’s the report: ftp://ftp.software.ibm.com/linux/pdfs/GCG_IBM_and_Linux-9_years_later.pdf
The opening teaser:
In 1999, IBM issued a series of announcements fully committing the company to supporting Linux. IBM vowed to Linux-enable all of their hardware platforms, including their non-x86 based mainframe, mini, and RISC-based systems. They also promised to release Linux versions of their software products and develop
Linux-centric service practices. Moreover, they pledged significant resources to the Linux community with the goal of advancing Linux and open source technology.So, nine years later, did IBM deliver on these promises? Was their commitment to Linux genuine or just lip service? This report examines IBM’s current Linux products, services, and community support in light of the promises they made in 1999…
While I think it’s obvious IBM has been a huge investor in the Linux community, one thing that I noticed reading the report is just how much IBM is actually different from other community members. There are some noticeable differences in the investments and approach to supporting the Linux platform and community. I often forget to just take in all the Linux technologies IBM has been heavily involved in from Xen, KVM and libvirt to filesystems, to systemtap, kprobes and then there’s RAS, scalability and performance enhancements.
Another interesting thought to reflect on is just how important it has been that there are multiple investors in this field. If this report captures just what IBM did, think of the industry combined. IBM couldn’t have done anything this big with Linux if it weren’t for co-creating with a community of enthusiasts, researchers, governments, Intel, AMD, Google, Nokia, Motorola, Oracle and thousands more. What would the report look like if you compiled all the investments and work the entire community leveraged across the industry. Linux is “bigger than huge” when you stop to think about it. This is also why I’ve said for a couple years now when you extend the investment model 3 to 5 years into the future, Sun and its anti-Linux, Solaris push against the tide of the industry loses in the end. I think we’re starting to witness that now. Sure, OpenSolaris is a great idea… it’s just 9 years late and it’s too late to matter now.
I’m interested in outside perspectives too - where do you think IBM stands? Has the community development and investment model worked? Where will this lead in the future and what will be the next evolution of the model? Red Hat seems to think the model will evolve to include increased customer co-creation - I tend to agree. Why? Because the incentive model to invest aligns very well - and when you have alignment, it almost naturally will happen.

What is real time Linux worth to you?
Justifying investments in a real time Linux platform is perhaps too easy given a new report from Tabb Group (URLs below). Purists may initially point out that the report is more focused on speed of execution which real time is not necessarily intended to provide. I’ll counter that argument right now by pointing out that most real time implementations do increase speed while still providing the benefit of determinism that real time is intended to offer. Besides, how can you ensure speedy execution across thousands of transactions if you don’t have a deterministic platform? Even the fastest drag race cars slow down eventually…
Add in real time Java and you have a fully deterministic stack.
16 percent of all U.S. institutional equity commissions are exposed to latency risk, totaling $2 billion, according to a new report from the TABB Group.

Using ext4 and migrating from ext3
A noticed a very interesting developerWorks article today on the ext4 filesystem.
http://www.ibm.com/developerworks/linux/library/l-ext4/index.html?ca=drs-
There’s a great summary table of the new features. Remember though, ext4 is still labeled experimental.
Ext4 is the latest in a long line of Linux® file systems, and it’s likely to be as important and popular as its predecessors. As a Linux system administrator, you should be aware of the advantages, disadvantages, and basic steps for migrating to ext4. This article explains when to adopt ext4, how to adapt traditional file system maintenance tool usage to ext4, and how to get the most out of the file system.

IBM Launches New Approach to Servers (errr… a twist on the Google approach) - and it’s all based on Linux
IBM launched its iDataPlex server systems today - think of it as a “Google” for your datacenter. It’s targeted at web workloads and is insanely dense and power efficient compared to traditional server buildouts. And it uses Linux on commodity hardware so it’s also ridiculously cheap. If you’re a web hosting shop or you have your own web farm that could use a serious overhaul, iDataPlex is a very cool solution.
Did I mention it only runs Linux?
Ashlee Vance cracks me up - it’s clear from this article he’s been talking to vendors for two long (see the last sentence in this quote):
The system itself is quite remarkable. IBM has reworked its approach to rack servers allowing it to place twice as many systems in a single cabinet. This attack centers on delivering the most horsepower possible in a given area while also reducing power consumption. IBM hopes the iDataPlex unit will attract today’s service providers buying thousands and tens of thousands of servers and also big businesses such as oil and gas firms and media companies that will also possibly pursue a grid-ish data center computing model pioneered to some degree by Google.
But the really awe inspiring bit of iDataPlex comes from the fact that IBM is willing to go after this market at all and that it did so without screwing up the hardware design.
Ars covered the details as well over here:

Adobe joins the Linux Foundation!
Awesome news from Jim and David! Hey, better late than never ;-)
“Adobe’s decision to join the LF is a natural extension of its commitment to open standards and open source, which demonstrates its leadership and foresight in the software industry,” said Jim Zemlin, executive director at The Linux Foundation. “Adobe’s membership will contribute to our goal of increasing even more application development on Linux with a specific emphasis on Web 2.0 applications.”
“Adobe delivers key RIA technologies for Linux users, such as Adobe® Flash® Player and now Adobe AIR™, to deploy RIAs in the browser and on the desktop,” said David McAllister, director of standards and open source at Adobe. “The Linux Foundation is a valuable resource, providing a forum where we can work with the community to ensure Adobe RIA technologies are compatible across the Linux software platform.”
This makes perfect strategic sense for Adobe. I can’t wait to see more Adobe desktop apps running on Linux. Adobe will be at the LF Summit and I believe are participating in DAM.
Press release here: http://linux-foundation.org/weblogs/press/2008/03/30/adobe-joins-linux-foundation-with-focus-on-linux-for-web-20-applications/

The Linux Foundation is looking for a Community Manager: it could be you!
If you read my blog, you’re a potentially interested party for a new Community Manager position at the Linux Foundation. One perk they didn’t list is that someone in this position will also get great visibility and interaction with the Linux leads and team members at the various member organizations (e.g. IBM, HP, Intel, AMD, Oracle, etc. etc.). If you’re interested in the Linux community, this is a great position to be in.
http://www.linux-foundation.org/en/Jobs#Linux_Foundation_Community_Manager
Linux Foundation Community Manager
Linux Foundation Community Manager
We’re looking for world class talent to join the non-profit organization that is accelerating Linux. If you’re passionate about Linux, there is no better place to work. We have a unique opportunity for the right individual to make a huge difference in Linux.
The Community Manager must have both a technical and business view of key issues facing Linux and can do the following:
- Organize workgroups by galvanizing member leaders and participants. Push agendas on calls and in Collaboration Summit meetings. Recruit the right people and enable them to lead the workgroups. This person will be the LF liaison between us and our members.
- Build community in these workgroups and in the general LF online presence by writing content, recruiting volunteers to write content and managing new web properties and strategies. This is a chance for you to be creative and be a thought leader.
- Be a technical source for Linux issues for LF management and prepare them for press and speaking opps in specific areas of expertise.
- Handle details around LF workgroups and advisory councils. You will own these groups so you are responsible for everytihng, down to the details. If you’re used to a large staff to handle details for you, this is probably not the right job for you.
- Assist LF staff with conference and events. This could be writing and leading workgroup sessions, recruiting the right people, speaking at conferences, etc.
- Assist engineering in LSB content and community. (Moderating forums, recruiting participants, etc. for a new Web property.)
- You must understand the Linux ecosystem, especially server-related Linux issues, and be technical. (You don’t have to be a kernel programmer but you need to know who they are individually. If someone says GCC you know what that means.)
- You need to be able to express yourself in writing but just as importantly you need to be able to organize and run a meeting. You need to be able to do details and get things done but also have a big picture view.
- You have to be politically savvy and understand motivations and sensitivities of divergent people and groups.
- Web programming or at least a high proficiency in new web strategies is preferred.
If you’d like to apply for this job, please send your resume to angela (at) linux-foundation (dot) org.

SELinux really does work as intended (and mitigates casualties)
Just saw this interesting update on some of the real world successes of SELinux.
Linux security experts are reporting a growing list of real-world security situations in which the US National Security Agency’s SELinux security framework contains the damage resulting from a flaw in other software. These so-called “mitigations” are showing that a Linux feature that began as an esoteric security measure is starting to prove its worth.
The article also references Dan Walsh’s LiveJournal entry here.

Jim Gleason - on - The Next Wave of Virtualization
Kernel-based Virtual Machine and its impact on the desktop Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure and open source hypervisor that provides both full and para-virtualization capabilities for Linux on commodity x86 hardware that contain the virtualization extensions from Intel and AMD. KVM is currently implemented as a loadable Linux kernel module. In late 2006, it was first included in Linux kernel 2.6.20 and and first shipped with OpenSuse 10.1 and Fedora 6.
Since KVM is part of Linux, KVM leverages the scheduler, memory management and other key resources in the Linux kernel, unlike VMware and Xen which must create their own custom mechanisms. Thus, KVM development focuses exclusively on the next-wave virtualization, while Xen and VMWare must also maintain these ‘forked’ non-Linux resources.
All of the core KVM developers, including Avi Kavity, work at the firm, Qumranet, which launched a desktop virtualization solution called Solid ICE that leverages KVM. Qumranet is the creator, maintainer and global sponsor of the KVM Open Source Hypervisor Project. Other high-ranking Linux kernel developers such as Rusty Russell and Anthony Liguori of IBM, Ingo Molnar of Red Hat, and Andrea Archangeli formerly of Novell, devote most of their time to KVM development.
What is the Next Wave of Virtualization?
Qumranet has gone beyond conventional server virtualization and application streaming by completely virtualizing end users’ desktop machines. From a browser on a thin client or PC, users access their desktop work environment over the network via a virtual machine running on a centralized server. The end result is a seamless end user work experience, just like a physical PC on a LAN. This is a high-level talk which will focus on the breakthrough Linux technology KVM, and its impact on the virtualization market.
About Jim Gleason:
Jim has been providing emerging technology to early adopters in the Financial Serivces Sector for the past ten years. Widely regarded as the person who brought Linux to Wall Street, Jim sold the first production Linux cluster to Goldman Sachs in 1998. Jim was also an early Internet pioneer having closed deals for the first official web sites of Charles Schwab, VISA, and all of Hewlett-Packard’s original web sites in 1993. Jim is also the Founder of the NY Linux Users Group and currently works at Qumranet in the capacity of Vice President of Sales.

Coverage on IBM’s Open Collaboration Client Solution with Ubuntu
Saw a few articles today on IBM’s OCCS announcement with Ubuntu.
Satyadas said IBM thinks that this year, it will happen. “All the stars are lining up,” he said. “Everybody has been saying that since 2001 except IBM. We never said that, but we are saying that now.”
It’s easy to overlook IBM’s announcement that its Lotus Notes and Lotus Symphony suites will run on Ubuntu. I think this would be a mistake. IBM is not a dumb company. It’s not in the habit of wasting resources. For IBM to be partnering up with Ubuntu says something about the enterprise mindset on Ubuntu.
By porting key software to Linux, IBM is looking to give businesses one less reason to buy products from rival Microsoft — which IBM said offers “a proprietary desktop model.” IBM’s Linux efforts will “further address customer demands around choice,” said Inna Kuznetsova, an IBM executive with responsibility for Linux, in a statement.

Ubuntu and IBM bring enterprise collaboration to a user friendly Linux desktop
I read this news release with great excitement and will take a shameless opportunity to plug what I think is a fantastic partnership. The news? IBM’s Lotus group has announced support of its Open Collaboration Client Solution (OCCS) for Ubuntu Linux. OCCS is a layer of rich client communications apps including IBM Lotus Notes 8.5 (Calendaring, Email), Sametime 7.x (Instant Messaging), and Symphony (OpenOffice in an Eclipse RCP form). I’ve switched to Ubuntu for my primary system at home for well over a year now and while I took a very short break to dabble in Fedora 8, I’m back on Ubuntu again. I’ve been using a RHEL5 base at work for over a year as well but now that we have Ubuntu support coming, I’ll probably switch to Ubuntu once the OCCS solution is released (yes, I work in a strategy group in IBM and I don’t use Windows or MS Office - and most people can’t tell). The thing about working in IBM is that everyone uses Notes, Sametime, and ODF is even becoming more popular so there’s very little that prevents anyone from using Linux (or a Mac). Heck, many users can probably get away with an iPhone.
IBM also expanded the OCCS platform support with Red Hat EL Desktop and announced more partners around OCCS on Novell’s Suse Linux Enterprise Desktop (SLED).
What makes all this even better? Enterprise applications delivered in a rich client environment. Take for instance SAP, who today announced a joint product set with IBM that will be delivered through Lotus Notes (which we now know runs well on Linux)
The product, codenamed Atlantic, will allow users to access SAP’s Business Suite applications for workflows, reporting and analytics through IBM’s Lotus Notes desktop software.
So the ecosystem and vision is starting to come together. It’s early, but I would be remiss if I didn’t mention again that 2008 will be the year of the enterprise Linux client ;-) How many users will we be saying this for? :-) (Note, I didn’t say ‘desktop’ specifically, and I said ‘enterprise’). As we’ve been saying all along, there are certain segments of users that can easily do their work on a Linux client (many won’t even know it’s not Windows). Those companies who take advantage of user segmentation have a lot to benefit from both on pure cost alone, but also in the next round of negotiations on your non-Linux client systems ;-)

Toshiba Spurs Engine: Cell processors in laptops and TVs … could it be an x86 and Power/Cell race in the datacenter?
There’s always a flood of news coming out of CES, but one that I find interesting that also impacts the server and technology market is a bit of news from Toshiba. As this video shows, Toshiba has embedded a Cell BE processor (yes, the same ones in PS3s) into a laptop and a television. The reason is that the Cell processor is far more capable of handling video rendering and stream computing than a typical general processor such as you find from Intel or AMD.
Now you may watch the video and then wonder ‘what the heck does this imply for the server market?’ and you’d be right to ask. Interestingly, Scott Handy from IBM recently did an interview with The Register and gave everyone the answer. The processor marketplace for desktops, laptops, mobile devices and servers requires huge volumes to provide economic returns to manufacturers. There is a huge capital investment that goes into every generation of processor not to mention all the IP that must be created to advance from one generation to the next. Similar to software sold on CD, producing the first chip may cost $1B and the second chip $500M, and it only gets cheaper as your volumes increase. In order to maintain a processor business profitably, chip makers live off volumes (hence the huge battles between Intel and AMD). Now the problem facing Intel for Itanium and Sun for SPARC is that these server technologies have no consumer application that will drive additional volumes. In terms of volume, the server market is a spec in chip consumption.
Yet the processor market is a rat race - vendors need enormous chip volumes to provide funding for future chip designs and whoever has the most funding, tends to produce the winning chips (see Intel for years despite competition from AMD). In fact one might point to Itanium as Intel’s decline - a chip that never saw the volumes needed to make it a competitive chip. Then as Intel was divesting profits from its x86 chips into Itanium chips, it suddenly found itself behind AMD. For a good grin, take a look at IDC’s forecasts for Itanium and the ‘revisions’ to those estimates. Heck, probably the only person to have worked around Itanium and advanced their career was Ashlee Vance.
Now look at Sun and SPARC and you see what used to be a high volume SPARC or UltraSPARC platform with many 1-4 way SPARC servers going into every datacenter giving Sun ‘good enough’ volumes to invest in future generations of processors. Then comes along Intel and Linux and Windows wiping out low end SPARC volume servers and cornering SPARC processors into a lower volume mid-high end server market. Without the funds for future generations of chips, Sun has to resort to stopgap measures craftily using old SPARC core designs in a Niagara multicore processor configuration. Regardless, that still doesn’t create high volume - the non-x86 server market is actually relatively low volume.
When you look at Power processors in everything from Mars rovers to cars, servers, printers and today it’s used in all 3 gaming systems (Xbox 360, PS3, and Wii). The gaming market alone consumes tens of millions of processors (far more than the server market). The Cell BE processor in the PS3 and IBM or Mercury Cell blades actually have 1 power core (PE) and 8 synergistic processing units (SPEs). The PE acts as a ‘router’ for instructions and data sent to the SPEs. So an application developer write much of the code similar to a power architecture when targeting a Cell based system. (Now I’m oversimplifying processor architectures a ton here, I’ll admit - but the point is not to debate the differences between PowerPC/POWER and Cell PE/SPE units… look at the big picture).
Now, going back to servers you can understand that winning in servers requires a high volume chip that funds future chip development and generates economic profits for the manufacturer. Without funds to invest in future chips, you lose the race. Once you view it all in this light, it becomes easier to see why the Power, ARM and Intel/AMD x86/x64 architectures are far ahead of other RISC or other architectures - they have volume. POWER6 was no small ’speed bump’ - POWER6 is a fierce chip with raw compute power and system throughput that leapfrogged its competitors. It took economic profits reinvested into chip design over years to create it. Cell is no different. And with Cell and Power having volumes in non-server markets including now potentially Toshiba laptops and TVs, I’ll leave you to place your bets on which architectures will be around in the server market for years to come.
Oh, and I should also note that Linux is the only OS that runs on both the Cell BE and POWER processors ;-) Guess which OS is likely to be around in your next generation server, television, printer and … well if only we could ‘fix’ the desktop/laptop market reliance on a different OS…

Two items to check out today: ODF-XSLT project and IBM developerWorks
First a website: I came across the ODF-XSLT project and I will say this is just the tip of the iceberg for where the world could head if documents are moved into an ODF format. Nonetheless this is very cool (I didn’t see a demo code project to download, but it looks extremely easy to setup). Anyway, check it out here.
The second is an article over at IBM’s developerWorks on “Multiprocessing with the Completely Fair Scheduler (CFS)”. If you have been paying attention to LKML over the last year you’ve seen plenty on this. CFS is a great new addition to the Linux kernel and Avinesh did a great job covering the new CFS features, rationale, data structures and finally how to actually use it. I also noticed a fair (pun intended) credit to Con Kolivas for being the one to prove fair scheduling could be done without wreaking havoc. Con’s frustration with getting his patches accepted has been well publicized, but it looks like his contribution will live on in the CFS code.
Some of these changes were made for these reasons:
- To enable better scheduling for servers as well as for desktops.
- To provide new features that were requested.
- To improve the heuristics. Those used in the vanilla scheduler made some attacks easy to implement. Also, if the heuristics gauged a scenario incorrectly, unwanted behaviors could result.

Daryl Stokes from IBM on open source virtualization
This looks like a great webinar (just landed in my inbox so I haven’t looked at it yet). I work with Daryl on a regular basis and am always impressed. Daryl also brought in Tony Iams from Ideas International who has a good knack for delving into the OS and platform details in a meaningful way. Hopefully my schedule will open up this afternoon to give me time to check it out before I head out on vacation!

The benefits of virtualization in the datacenter are becoming well-known: Server consolidation, capabilities to deploy more applications and virtual machines on a single server, cost savings, power savings. Do these benefits encompass open source virtualization as well? Are there additional benefits of open source virtualization that would justify a serious evaluation against current solutions on the market today? Join Ziff Davis Enterprises for this panel on pairing server virtualization and open source technologies to learn more about how datacenter IT managers can achieve lower TCO, gain flexibility in a mixed-source environment, and increase data center efficiencies. The panel includes an analyst’s overview on open source alternatives for virtualization, a case study by an integrator on implementation, and explores:

Resizing a KVM Windows virtual disk image
Just noticed the incoming link from Bryan Murdock on how he went through the process of resizing a Windows virtual image in a qcow2 file format to add more disk space on the virtual image. I haven’t actually done this myself, but it looks like there are issues resizing an image that has an NTFS filesystem. If you need to resize your image, check out Bryan’s post on how he did it here. (I like his method better than others)
I also found a good wiki page (I think it’s new) showing the guest OS’s that work (or don’t work) with KVM.

Insanely scalable filesystem service: SOFS
I just learned that in a Scale Out File Services (SOFS) solution a customer can implement a global filesystem (with clustering/replication) that has a maximum filesystem capacity of 33,554,432 Yobibytes. I actually had to look up Yobibyte. The maximum size for a single file is 16 Exibytes. That’s insanely scalable. Oh, and it’s all based on RHEL5 ;-)
The IBM website that has more info is available here.

InfoWorld: “Why Microsoft Rattles The Patent Saber”
Interesting article over at InfoWorld:
Imagine you’re Microsoft and you’ve spent years struggling to get
Windows Server 2008 out the door and will be struggling afterward to add server virtualization? Then along comes Linus Torvalds and his merry band and they add KVM to the Linux kernel over the course of a few months, release a new kernel for review every 2 to 3 months, and attract thousands of developers interested in the new features. Linux had both VMware and Xen hypervisors running on it just fine. Now it’s got another one freely available inside the kernel. It must feel in Redmond like Linux steals from the rich to give to the poor.
and…
Now the Linux kernel development process, which has been under way for 16 years, represents the largest, most complicated ongoing software development project in the world, with the possible exception of Windows itself. It’s moving fast, fluidly filling niches that Microsoft in the past had staked out. It’s leading in virtualization, in virtual appliances, in mobile devices. It’s threatening Windows on a number of fronts.

IBM Partners with Mainsoft to bring .NET apps to WebSphere Portal (and Linux)
The title says it all. I’m pleased to see the press releases have hit the wires (even though some may argue press releases are in the past). IBM customers can now purchase Mainsoft’s .NET Extensions for WebSphere Portal to start integrating their .NET based Windows applications into IBM WebSphere - which gives users the flexibility to deploy on any OS platform that WebSphere runs on (I prefer to say Linux).
I’ve worked with the team at Mainsoft for a while now and am pleased to see this relationship has moved another step closer. The ability to remove the middleware lock-in associated with the Microsoft programming model is exceptionally helpful for many users - especially those with volumes of .NET assets in their company.
If you haven’t tried out Mainsoft before, you can also use their ‘free’ tool called Grasshopper. You can download Grasshopper here: http://dev.mainsoft.com/
What the Mainsoft tools let you do is add a plug-in for Visual Studio into your IDE. You basically open up your .NET app and then publish it to a WebSphere (or other Java app server) using the usual VS.NET process. It’s really that easy. In the background, VS compiles your .NET code into intermediate .NET bytecode, then Mainsoft kicks in and translates the bytecode to Java bytecode, wraps up the code into JAR/WAR files to deploy on the server. You might think it’s “magic”, but it’s real - and customers are using it to break free from the Microsoft lock-in (some even on Mainframes - how crazy is that?).
Congratulations to Mainsoft and the IBM Portal team who have turned a successful relationship into one built for volume and scale.

Running Windows Server 2008 with KVM on Linux
See my prior post on KVM if you want to get started with KVM setup. Assuming you have KVM working on your system, it takes just 3 easy steps to get started using Windows Server 2008 on Linux in KVM. Before starting, you must have a copy of Windows Server 2008 of course. If you don’t have one handy, you can download and burn an eval DVD ISO from here.
Once you have your DVD ready, just execute the following in a terminal:
- # qemu-img create win2008EE.img -f qcow 10G
- # kvm -m 750 -cdrom /dev/cdrom -boot d win2008EE.img
- # kvm -m 500 win2008EE.img
That’s it. Windows Server 2008 seems to require ACPI so the -no-acpi option gave me an error. I will also note that I could not get the 64-bit Enterprise version working and instead opted for the 32-bit Standard (I suspect the issue is the 64-bits and has nothing to do with the edition).
First impression: Windows Server 2008 will feel just like Server 2003 and in some ways feel different. It does seem to startup/shutdown faster than before but there are so many variables it’s hard to tell. 2008 is actually quite visually appealing… can’t point to one thing, but the polish is nice for a server version (I’d call it a Vista minimalist look). Server 2008 of course has all the Microsoft GUI config screens newbie Linux admins dream to find… you have to give Microsoft credit for making it very simple to access and setup server services out of the box.
Microsoft has made quite a few changes (I haven’t explored them all) and I have not used the Core version yet. One noticeable change is (sit down for this)… IIS 7.0 has gone modular - yes, it’s true. Setting up IIS 7.0 will actually look like you’re installing packages using a Yum or Apt-Get GUI. You will be asked to confirm “features” which are akin to dependencies. Whoever redesigned IIS used Apache and Linux - the influence is notable.
I’m barely scratching (or seeing) the surface here so I’ll end with a promise to post more as I play around with the eval over the next few weeks.
Oh, I guess I did also skip the fourth step:
4. Install Windows Server anti-virus, anti-everything security software :-)
And here are some screenshots for those who are interested or require visual confirmation:
