Mainframe OpenSolaris Now Available 135

BBCWatcher writes "When Sun released Solaris to the open source community in the form of OpenSolaris, would anyone have guessed that it would soon wind up running on IBM System z mainframes? Amazingly, that milestone has now been achieved. Sine Nomine Associates is making its first release of OpenSolaris for System z available for free and public download. Source code is also available. OpenSolaris for System z requires a System z9 or z10 mainframe and z/VM, the hypervisor that's nearly universal to mainframe Linux installations. (The free, limited term z/VM Evaluation Edition is available for z10 machines.) Like Linux, OpenSolaris will run on reduced price IFL processors."

    The way I see it, IBM is in the business of providing so much choice to customers that they need expensive IBM consultants to help them decide.

    Microsoft will sell you the Microsoft Way of doing things.

    Whereas IBM will say "You want a Active Directory server, a Z mainframe with RedHat, OpenSolaris and Oracle, Cisco switches, and there must be full J2EE buzzword compliance? No problem, just sign here".

    Careful to make sure they will actually do the job though, and not outsource it to a bunch of fresh PHP coders in India ;).

      Now if a Solaris shop needs some big Iron IBM can walk right in and sell a Z to them.

                • Sure they do, at least in most mainframe operational organizations. (Non-mainframe operations are a different story. You ask "what about avoiding planned outages?" and they look at you funny.) In fact, it's even possible the reboots aren't actually happening, but the operators have reserved the right (in the SLA) to do them, so they declare that early Sunday mornings (for example) are planned outages. If you want a different SLA, ask for it. This certainly isn't a technical problem.

Granted, I'm totally at the mercy of the Mainframe admins that control DASD access. It doesn't matter though, even if I had faster IO, you still have to have the CPU to process the data once it's been retrieved. My tests showed that the CPU spent less time in IO wait, but they were so slow to do anything else, it didn't matter.

        From what I've seen in a SAN in a mixed environment, it certainly isn't the mainframe that's exposing the FC bottlenecks. It's a long time ago that the mainframe had any special hardware.

        Frankly, I've heard so many sales pitches for so long that there's only one thing that matters. Publish the benchmarks or it's just hot air.

        In the case of mainframes I haven't seen any serious benchmarks for more than a decade. I expect performance to be entirely predictable from that point only.

    Every time a mainframe story comes up on Slashdot we seem to get the skeptics who point out that an X86 processor core can add or multiply two numbers (stored in registers anyway) about as fast as a single System z10 core, at least as long as they're integers. (z10s have hardware decimal floating point.) Based on this brilliant SPECint-y observation, combined with the fact that a System z10 EC Linux processor has an advertised one-time charge of $125K, these "experts" thus conclude that no one could possibly buy a mainframe because it's just so darn expensive. (Note that's one-time charge, folks: if you do a hardware model upgrade typical IBM practice is to charge you something for the frame swap but not to charge you again for turning on the processors.) Of course, in the same discussion people don't bother to explain why the same argument also holds for SPARC CPUs. Heck, why not run business applications on Sony Playstation 3s or ARMs? They're even "cheaper."

    May I humbly point out that IBM just posted (yesterday) another record quarter for mainframe sales. Revenues were up 25 percent, with double digit growth in every region of the world. Because prices are higher? No, the opposite: shipped capacity was up 49 percent; specialty capacity (including Linux processors) was up 120 percent. And IBM has been posting quarters like this for years now. This mainframe stuff is wildly successful and gaining marketshare.

    Why? Because, with all due respect, you're an idiot if you stop your careful business case analysis at the first sentence above. Unless you're running SETI@Home, rendering the next Pixar movie, or simulating nuclear explosions, business applications across many users just don't run that way. Companies (particularly CFOs) and big data center managers are not (generally) idiots. They buy this stuff because it works wonderfully and because it's cost-effective, taking all costs into consideration. Think $125K (once) is a lot of money? What's your salary, dude? Who are the richest single human beings in the software industry, and did they get that way because software is free? And how much did it cost the London Stock Exchange when they couldn't trade? Are you the guy who wants to explain why you have to build another $20M data center because you can't power or cool yet another X86 chip? In the real world, there are single companies running hundreds of these mainframe CPUs. And they run at 80%+ busy 24 hours a day, by the way.

    Honestly, there are way too many Slashdotters who are much more the stubborn non-thinkers that they probably accused mainframe-skilled people of being a few years ago. It's a different world: grow up. The boring but wonderful truth is that -- surprise! -- different servers are good at different things! Intel/AMD X86 servers are useful in certain ways, and so are System z servers. Even in the same data center. Wow, what a concept!

      Even discounting all of the good points you've made, System/Z has one other advantage. It's a direct descendant of System/360 and still runs software written in 1960 without a recompile. The same mainframe can now also run virtual Linux and Solaris instances. Sure, you could run something like Hercules on your x86 machine, but who would support it, and would you trust it on that bit of critical software that has been supporting your business for almost fifty years?
