One to follow?

Nepotism rocks, it makes the world go around. Ok, ok, maybe not. However, when one of your personal friends, that until a few years ago you never even knew worked in IT, starts writing a great, to the point blog, what’s a man to do except provide a link. Here it is, Jays “Technology Defenestration” blog.

Hey Jay, when you get a minute, do me a favor, read this paper of mine on virtualization from 2006 and try to put Oracles hard and soft partitioning in context. Cheers.

Unix migrations and game changers

More product talk, much closer to home for me are this weeks new Dell PowerEdge servers including the PowerEdge R910 which was specifically designed and configured for a market segment I’m fully aware of, RISC Server migration.

It’s well worth taking a look at this youtube video from the R910 h/w design team, for me this is something that I just think people don’t realise, just how much clever design goes into the Dell PowerEdge servers. I think this, better than anything else I’ve seen, embodies the difference between peoples perception of what Dell Server engineering does, and what we actually do. I can honestly say that even back to my IBM mainframe days, I’ve never seen a better designed, more easily accessible, configurable and thought out server.

In terms of configuration the R910 is specifically aimed at those who are rethinking proprietary UNIX deployments either on SUN SPARC or POWER AIX. Based on industry standards and the x86 architecture, the R910 is an ideal platform for RISC/UNIX migrations, large database deployments and server virtualization implementations. It’s a 4U rack server is available with a high-performance four-socket Intel Nehalem-EX processor, up to 64 DIMM slots for memory, redundant power supplies and a failsafe embedded hypervisor resulting in the performance, reliability and memory scalability needed to run mission critical applications. It also includes an option to have 10Gb ethernet right on the motherboard.

There are 3-other new servers this week, including the M910 Blade server, the R810 virtualization and consolidation server and the R815 virtualization, high-performance computing, email messaging, and database workloads server.

The PowerEdge R815 deserves it’s own “shout-out”, it comes with the same level of detail in h/w design as the R910, but is powered by the brand new 12-core AMD Opteron 6100 processors and has up to 32 DIMMs with up to 48 processor cores in a four-socket, 2U server.  As my friend and former IBM colleague, Nigel Dessau, now Chief Marketing Officer at AMD put it, the new AMD processors are “game changers

All this weeks new servers include the iDrac embedded management that our team works on, as well as the  Dell Lifecycle Controller. Lifecycle Controller provides IT administrators with a single console view of their entire IT infrastructure while performing a complete set of provisioning functions including system deployment, updates, hardware configuration and diagnostics.

For customer who are interested in migrating from proprietary UNIX environments we are also now offering a set of migration services to an open server platform and an open OS.

Oracle gets big on Sun

Predicting the Future, The Oracle concept watches by Designer Andy Kurovets mixes time with Chinese philosophy

Predicting the Future, The Oracle concept watches by Designer Andy Kurovets mixes time with Chinese philosophy

Fascinating news. I didn’t see a single consultant, analyst, journalist predict this. WRT to the supposed IBM/SUN on/off deal, I guess the biggest part to work out is how this will effect Oracle products on IBM Power Systems servers.

Oracle was definately the most significant software product on Power systems, I assume if Oracle decides it wants to keep the SPARC hardware architecture alive, it’s going to have to start favouring SPARC over Power. If nothing else, one assumes the fees IBM pays Oracle for Power support/currency/testing etc. will likely go up. Fascinating indeed.

I guess that also puts Oracle into competition with Dell and HP too, not just becuase of their SUN x86 hardware, but also again for platform currency. I didn’t dial-in to the investor call this morning, but I wonder how many are already wondering what the chances are of Oracle spending a year to work out how to sell-off the parts of Sun it doesn’t want, like the hardware business, but keeping the bits it does want, like Java and the other key software assets and intellectual property. Fascinating indeed.

However, if this knoxnews.com picture is anything to go by, Oracle have some work to do on their Industrial design and human factors for their hardware.

Whither IBM, Sun and Sparc?

So the twitterati and blog space is alight with discussion that IBM is to buy Sun for $6.25 billion. The only way we’ll know if there is any truth to it is if it goes ahead, these rumors are never denied.

Everyone is of course focussed on the big questions which mostly are around hardware synergies(server, chips, storage) and Java. Since I don’t work at IBM I have no idea whats going on or if there is any truth to this. There some more interesting technical discussions to be had than those generally think they have an informed opinion.

IBM bought Transitive in 2008; Transitive has some innovative emulation software, called QuickTransit. It allows binaries created and compiled on one platform, to be run on another hardware platform without change or recompilation. There were some deficiencies, and you can read more into this in my terse summary blog post at the time of the acquisition announcement. Prior to acquisition QuickTransit supported a number of platforms including SPARC and PowerMac and had been licensed by a number of companies, including IBM.

I assume IBM is in the midst of their classic “blue rinse” process and this explains the almost complete elimination of the Transitive web site(1), and it’s nothing more sinister than they are getting ready to re-launch under the IBM branding umbrella of POwerVM or some such.

Now, one could speculate that by acquiring SUN, IBM would achieve three things that would enhance their PowerVM stratgey and build on their Transitive acquisition. First, they could reduce the platforms supported by QuickTransit and over time, not renegotiate their licensing agreements with 3rd parties. This would give IBM “leverage” in offering binary emulation for the architectures previsouly supported, on say, only the Power and Mainframe processor ranges.

Also, by further enhancing QuickTransit, and driving it into the IBM microcode/firmware layer, thus making it more reliable, providing higher performance by reducing duplicate instruction handling, they could effectively eliminate future SPARC based hardware utilising the UNIX based Power hardware, PowerVM virtualization. This would also have the effect taking this level of emulation mainstream and negating much of the transient(pun intended) nature typically associated with this sort of technology.

Finally, by acquiring SUN, IBM would eliminate any IP barriers that might occur due to the nature of the implementation of the SPARC instruction set.

That’s not to say that there are not any problems to overcome. First, as it currently stands the emulation tends to map calls from one OS into another, rather than operating at a pure architecture level. Pushing some of the emulation down into the firmware/microcode layer wouldn’t help emulation of CALL SOLARIS API with X, Y, even if it would emulate the machine architecture instructions that execute to do this. So, is IBM really committed to becoming a first class SOLARIS provider? I don’t see any proof of this since the earlier announcement. Solaris on Power is pretty non-existentThe alternative is that IBM is to use Transitive technology to map these calls into AIX, which is much more likely.

In economic downturns, big, cash rich companies are kings. Looking back over the last 150 years there are plenty of examples of big buying competitors and emerging from the downturn even more powerful. Ultimately I believe that the proprietary chip business is dead, it’s just a question of how long it takes for it to die and if regulators feel that by allowing mergers and acquisitions in this space is good or bad for the economy and the economic recovery.

So, there’s a thought. As I said, I don’t work at IBM.

Virtualization, The Recession and The Mainframe

Robin Bloor has posted an interesting entry on his “Have mac will blog” blog on the above subject. He got a few small things wrong, well mostly, he got all the facts wrong but, right from a populist historical rewrite perspective. Of course I posted a comment, but as always made a few typos that I now cannot correct, so here is the corrected version(feel free to delete the original comments Robin… or just make fun of me for the mistakes, but know I was typing outdoors at the South Austin Trailer Park and Eatery, with open toe sandles on and it’s cold tonight in Austin, geeky I know!)

What do they say about a person who is always looking back to their successes? Well, in my case, it’s only becuase I can’t post on my future successes, they are considered too confidential for me to even leave slides with customers when I visit… 

VM revisited, enjoy:

 

Mark Cathcart (Should have) said,

Actually Robin, while it’s true that the S/360 operating systems were written in Assembler, and much of the 370 operating systems, PL/S was already in use for some of the large and complex components.

It is also widely known that virtualization, as you know it on the mainframe today, was first introduced on the S/360 model-67. This was a “bastard child” of the S/360 processors that had virtual memory extensions. At that point, the precursor to VM/370 used on the S/360-67 was CP-67.

I think you’ll also find that IBM never demonstrated 40,000 Linux virtual machines on a single VM system, it was David Boyes of Sine Nomine, who also recently ported Open Solaris to VM.

Also, there’s no such thing as pSeries Unix in the marketing nomenclature any more, it’s now Power Systems, whose virtualization now supports AIX aka IBM “Unix”, System i or IBM i to use the the modern vernacular and Linux on Power.

Wikipedia is a pretty decent source for information on mainframe virtualization, right up until VM/XA where there are some things that need correcting, I just have not had the time yet.

Oh yeah, by the way. While 2TB of memory on a mainframe gives pretty impressive virtualization capabilities, my favorite anecdote, and it’s true because I did it, was back in 1983. At Chemical Bank in New York. We virtualized a complete, production, high availability, online credit card authorization system, by adding just 4Mb of memory boosting the total system memory to a whopping 12Mb of memory! Try running any Intel hypervisor or operating system on just 12Mb of memory these days, a great example of how efficient the mainframe virtualization is!

 

It’s a performance double-up for Power!

That got your attention didn’t it?

We’ve announced another performance and benchmark record this week, IBM WebSphere Application Server benchmark involved more than 109,850 concurrent clients and produced 14,004.42 SPECjAppServer2004 JOPS@Standard (jAppServer Operations Per Second), which translates into more than 50 million business transactions over the course of the benchmark’s hour-long runtime. That’s a lot of clients, and a lot of transactions!

The performance run was completed on IBM POWER6 BladeCenter servers powered by two dual-core IBM® POWER6® 4.0 GHz processors and IBM DB2 Universal Database v9.5 on a System p p595 running AIX.

We ran the test over 52-processors, 2-cores per processor and with SMT on. The software config included 26 WAS instances. Now, the issue here isn’t performance, 26-instances isn’t so bad from a config and deployment perspective either. But wouldn’t it be better if you could bundle that all up into a couple of racks and use cloning, automatic deployment, recovery, scheduling etc. and on an even more consolidated, energy efficient platform.

Funnily enough, we are working on that. The IBM Press release mentions IMPACT 2008, that might be good timing, I won’t be there as I’m off to do the Machu Picchu thing at the start of April.

Prior to the new WebSphere+Power double-up, the 4Q2007 record was held by Oracle on HP-UX Integrity Server Blade Cluster, with 10,519.43 JOPS over 24 server instances on 22 2-core processors; Sun also submitted a SPARC T5120 SPECjAppServer2004 benchmark with Sun Java System Application Server 9.1 running 6-nodes, 18-server instances on 48-cores, 6-chips and only scored 8,439.36 JOPS.

On PowerVM, Lx86 and virtualization of Windows

PowerVM logo Yesterday saw the announcement of a re-packaging, re-branding and new technology drive for POWER™ Virtualization now PowerVM™. You can see the full announcement here. It is good to be back working on VM, sorta.

Over on virtualiztion.info, Alessandro Perilli, says we are “missing the market in any case because its platform is unable to virtualize Windows operating systems”. I say not.

POWER isn’t Windows, it’s not x86 hardware. We scale much, much higher, perform much better and generally offer high availability features and function as standard or an add-on, way ahead of Windows. Running Windows on PowerVM and Power hardware would pick-up some of the reliability features of the hardware transparently, and the workload consolodation potential would be very attractive. What it comes down to though, is what it would take to virtualize Windows on PowerVM?

We could do it. We could add either hardware simulation or emulation or more likely translation that would allow the x86 architecture or Windows itself to be supported on PowerVM. There would be ongoing issues with the wide variety of h/w drivers and related issues, but lets put those aside for now.

We could have gone down a similar route to the old Bristol Technologies WIND/U WIN32 licensing and technology route, porting and running a subset of WIN32 or even via mono or .net. We might even call it PowerVM Wx86. Just reverse engineering MS technology is neither the right idea from a technology or business perspective.

So technically it could be done one way or another. The real question though is the same as the discussion about supporting Solaris on Power. Yes, it would be great to have the mother of all binary or source compatibility virtualization platforms. However, as always the real issue is not if it could be done, but how would you support your applications? After all isn’t it about “applications, applications, applications“?

And there’s the rub. If you wanted to run middleware and x86 binary applications on POWER hardware, then you’d need support for the binaries. For middleware, most of the industries leading middleware is already available on either of AIX, i5/OS or Linux on Power, some is available on all three. What would software vendors prefer to do in this case? Would they be asked to support an existing binary stack on Windows on PowerVM, or would they prefer to just continue to support the native middleware stacks that benefit directly from the Power features?

Most would rather go with the native software and not incur the complexities and additional support costs of running in an emulated or simulated environment. The same is true of most customer applications, especially those for which the customer doesn’t have easy or ready access to the source code for Windows applications.

In the x86 market, the same isn’t true, there’s less risk supporting virtualization such as Xen or VMware

The same isn’t true with PowerVM Lx86 applications. First because of the close affinity between Linux and Linux on POWER. There are already existing Linux on Power distributions, the source code is available, and most system calls are transparent and can be easily mapped into Linux on POWER. Second, drivers, device support etc. is handled natively within either the POWER hardware, PowerVM or within the Linux operating system, running in the PowerVM partition. Thirdly, IBM has worked with SuSe and RedHat to make the x86 runtime libraries available on Linux on POWER. Finally, many middleware packages already run on Linux on POWER, or it is available as open source and can be compiled to run on Linux on POWER.

All of which makes it a very different value proposition. Using NAS or SAN storage, it is perfectly possible to run the same binaries currently or as needed on x86 and PowerVM. The compilcations of doing this, the software stack required, as well as the legal conditions for running Windows binaries just don’t make it worth the effort.

Although not identical, many of the same issues arise running Solaris, either Solaris x86, or OpenSolaris PowerPC port. So, thats a wrap for now, still many interesting things going on here in Austin, I really well get back to the topic of Amazon, EC2 and loud computing, memo to self.

Update on Solaris and IBM Systems…

No, not Solaris on Power, but today my long time buddy and fellow IBM Distinguished Engineer, Jim Porell, is gushing about their demo of Solaris on System z(aka the mainframe). Still no word on middleware and application vendor support. Thats when it gets interesting until then it will be a another open source and development option.

Jims’ flow can be read here. My original comment and opinion on this, here.

Predict the future, rewrite history

While sitting around this evening listening to the zdnet, David Berlind and Redmonk webcast, Monkcast #12: IBM HW group OEMs Solaris to chagrin of SW group & a fly in VMware’s ointment and both on the show and a web article, a few things came up that were worth commenting on, if for no other reason than to save history from being rewritten:
