The Eternal Mainframe 225

theodp writes "In his latest essay, Rudolf Winestock argues that the movement to replace the mainframe has re-invented the mainframe, as well as the reason why people wanted to get rid of mainframes in the first place. 'The modern server farm looks like those first computer rooms,' Winestock writes. 'Row after row of metal frames (excuse me—racks) bearing computer modules in a room that's packed with cables and extra ventilation ducts. Just like mainframes. Server farms have multiple redundant CPUs, memory, disks, and network connections. Just like mainframes. The rooms that house these server farms are typically not open even to many people in the same organization, but only to dedicated operations teams. Just like mainframes.' And with terabytes of data sitting in servers begging to be monetized by business and scrutinized by government, Winestock warns that the New Boss is worse than the Old Boss. So, what does this mean for the future of fully functional, general purpose, standalone computers? 'Offline computer use frustrates the march of progress,' says Winestock. 'If offline use becomes uncommon, then the great and the good will ask: "What are [you] hiding? Are you making kiddie porn? Laundering money? Spreading hate? Do you want the terrorists to win?"'"

    Wow, so deep. Computer is the Internet, Internet is the computer.

    Mainframes are specialised equipment, server farms are almost generic computers with redundancies. The real difference is the cost. Today's server farms would cost many factors more if they were built with specialised mainframes, there is no other real difference, they are really there for the same purpose.

      Right and there are some big differences:

      Mainframe CPU's tend to have far more error detection and correction. They have safeguards against errors in data shuffling and computation inside the CPU itself. Mainframes tend to offer robust job control, by the time you add decent job control of the level that mainframes offer your network of workstations/servers starts getting complicated
      Mainframes tend to offer decent encryption and security.

      Can you do all these things on a pile of VM's? Sure. Is it cheaper - maybe. Is it fun to manage - not particularly.

        I agree these are all differences for a regular pile of VMs in a server room, but if you look at some of the more developed server farms, they do have a lot of the mainframe-like features, at least on the software side.

          "Google, for example, has pretty full-featured job control layered on top of their server farm."

          Google has never cared about errors.

          Who gives a damn if what absolutely positively SHOULD have been the very first result is instead the fourth or the fifth result, or if it appears on page two of the results, or if it somehow magically disappears into the ether because commodity server #XJ42 in rack #43HB on aisle #521JJ in column #447F in building #QQZ1 in server farm #H61M happened to have crashed just as the query response was being assembled?

          Especially if the query involved "Justin Bieber", "Lindsay Lohan", or "Natalie Portman Hot Grits".

          IBM, on the other hand, has always cared about errors - has always, in fact, been FANATICAL about errors.

          If you send a query to an IBM mainframe, then you're expecting umpteen-sigmas of confidence that the mainframe will actually be up and running, that you'll get an actual response, and that the response, when it finally arrives, will be 100% CORRECT.

          Especially when the response is something along the lines of "DANGER: CHILD KNOWN TO BE ALLERGIC TO AMOXICILLIN. ALLERGIC RESPONSE INCLUDES ANAPHYLACTIC SHOCK. PRESCRIPTION REQUEST THEREFORE INVALID AND REFUSED."

            You have no idea what you're talking about. Dropping the occasional search result is fine, but what about failing to record billing for the ad system, dropping mails you were supposed to receive in your Gmail account, or failing to save the doc you were editing? Google does a lot more than serve search results, and most of that needs to work every single time.

            The fact of the matter is that even the most expensive hardware eventually fails, so your software needs to be able to deal with it and fall back to working units. Once you've written your software to handle hardware failures, you can run on really cheap hardware. And, it turns out that buying a lot of really cheap computers some of which are broken all the time gets you way more computing power than trying to buy a few really robust machines.

        I work with mainframes for a living. Specifically, I work with Linux on IBM zSeries mainframe for a bank. The idea is the provide the software depth of Linux with the reliability of the zSeries hardware.

        We get a fair amount of resistance from the Lintel bigots, mostly those who still think of the mainframe in 1980's terms. The current generation of mainframe packs a LOT of horsepower, particularly I/O capacity, in a relatively small box. It connects to the same storage and network as the Lintel servers do, but can one of those do 256 simultaneous DMA transfers? We don't sell the platform as a solution for everything, but we've done the TCO math and we're not that different from an Intel server farm once you factor in the external costs.

        I periodically give a class to the Linux admins on the mainframe in general, Linux on z, and the differences between that and Linux on Intel. If you didn't know where to look, it would take you a while to figure out you're not on Intel anymore. Most of the attendees are surprised at what the current boxes are like.

It is nearly 100x the cost and still takes 10x longer to crunch, index and search 8PB of data on mainframe as it does in a comparatively free Hadoop cluster. The TCO was laughably different.

If it was cost effective, don't you think Amazon would be running its cloud services on them?

              The last TCO I was involved with actually showed that the mainframe was the more cost effective approach for the use case at hand.

              As for Amazon, well that is hard to say. If when they first started, they knew how successful they were going to grow and how quickly, maybe they would have gone with a mainframe solution.That's the nice thing of TCO analysis, it eliminates, or should eminiate, any platform bias the decision makers have. Then again, it also depends on really knowing what future growth patterns and expected use cases are or it is just more GIGO.

        That stuff is also in hardware, which is only beginning to happen in the commodity pc world.

        For a certain type of workload, at a certain level of necessary uptime, mainframes start becoming cost effective. Fun things like where IBM will install as many CPUs as you want, but only charge you for their time when you use them. This can be very cost effective for businesses with seasonal volume shifts. At some point, paying IBM $1000 an hour for their support is cheaper than paying 20 creeps with greasy hair to change hard drives, stack servers into a rack and fuck up the rollout of new VMs. It's kind of like trucks versus trains. Each have their place, but neither is very good at emulating the upsides of the other.

          What's the memory bandwidth of that x86 desktop or laptop roughly? Special points if they break out cache.
          Ask them how many dhrystone MIPS (very roughly) that uP has.
          Ask them the ratio of the main system memory bandwidth to MIPS.
          Ask them the ratio of the main system memory bandwidth to the I/O storage they have.

          They just never get exposed to this stuff. They just have no reference. Now ask them to compare them even to a regular 286 era ISA bus PC: I'll even give you some numbers.

          286/16 ~ 4K dhrystone MIPS on a good day
          Disk (40 MB IDE on ISA) ~ 400K/sec

          Mainframes run modern software. They run it extremely cost effectively for the throughput they have, moreso than any other platform. The run it with extreme reliability and uptime. They run modern DBMS, they run enterprise java and all other modern languages, they can and do run Linux and Linux business apps. they can run x86 software on X blades.

      The general thinking of comparing the two is that both systems are the ones running running the show, storing the data, and being accessed by dumb-clients that only serve as terminals.

      Obviously server farms and mainframes are very different from a back-end technology standpoint, but from a viewpoint of the user they are identical in every single way.

    There was a time when we expected computers to become so easy that everyone could use them. We've given up that dream. Now it's all "managed" again. There are admins and users again, and the admins (or their bosses) decide what the users can do and how. Computing is no longer done with a device you own but a service that someone else provides to you. Yes, you still pay for a device, but that's merely an advanced terminal.

    I blame the users. If they bothered to learn even a little about how things work, they wouldn't give up their freedom so easily. The complacency is staggering. Even people whose job depends on being able to efficiently work with computers often perform repetitive tasks manually instead of learning how to use more of the program they're working with. Of course, with users like that, who refuse to learn how to use what capabilities are already at their disposal, there's a market for the simplest automation performed as a service.

    I mean, not every server farm or server room can be compared to a mainframe. But these days, when companies have VMWare clusters and what-ever clouds, it is impossible not to draw a comparison since, functionally (and sometimes structuraly) they are pretty much like mainframes.

Each blade is going to be bottlenecked by its few SAN links, each is ever only going to be able to give a VM at most its full CPU core count and nothing more (can't run a single vm across multiple blades for performance improvement), if a blade fails without warning then HA will take a while to spin up and continue on another blade

    Someone in the industry realizes that computing is really iterative and what's old will eventually become new again.

    I believe the origin of this periodic realizations is as follows:
    (I intentionally used "jargon" instead of "technique", since the need to create a new term doesn't seem proportional to the actual change in implementation)

    1. A college fresh out get hired at a I.T. farm armed with a new set of computing jargon that impresses human resources.
    2. He applies his version of how things should work to the current workplace and things progress well.
    3. Over the next few years the department grows and new hires are brought in to help meet demand.
    4. The new hires start preaching their version of computing jargon that was created by academia to publish a paper.
    5. The once college fresh out comes to the realization that the new computing jargon are practically synonyms for the previous generation's jargon.
    6. The new hire proceeds to step #1 and the circle of I.T. begins anew.

    The neat thing about this iterative process is that the difference in implementation of the jargon between generation N and N - 1 are small enough to not seem that much different. However the difference in implementation of jargon between the current generation and the people hired 5 to 10 cycles prior can and usually are dramatic.

    I entered the field when distributive computing and storage with localized networks were being created and evangelized. Scientific computing had to be performed at universities and anything serious had to be done by renting time on a supercomputer connected via the internet. Medium sized businesses had to rent time on mainframes to perform payroll or hired firms specializing in payroll which still exists today. Small businesses had no access to computing until personal computers and single user applications came into use. Because of the newer businesses being more familiar with distributive computing than centralized computing, they scaled personal computers up to meet the new demands. This ability to scale computing power up allows the company to grow the computing infrastructure as needed. This was not possible with mainframes. Eventually the company grows to the point that it needs to have their data and application centralized and use data centers to handle the load.

    If you step back and look solely at the physical structure (e.g. data center, clerical offices) it resembles the centralized computing from 50 years ago. However if you look at the actual data and computing flow you'll see that its a hybrid of central and distributed computing that was not imagined in the past 20 years. It's more fractal in nature. Your computing at any given moment can be centralized to your terminal, your home, your office, your department, your company, or even global (e.g. Google, Github).

    I declare this to be known as BTE's law. ;)

    • This ability to scale computing power [...] was not possible with mainframes

      Are you having a laugh?

      • In context of money required. Small businesses normally couldn't afford one mainframe much less more than one.
      • You are correct that I should be more explicit about the relationship between scalability and expense. Smaller computing platforms can be scaled up in smaller steps requiring less money up front than mainframes.
        • I may have to be more explicit by stating that the computing unit size of small computing platforms is such that allows scalability in power from the end-user up. This scalability is accessible to more people and therefore encourages a change in the field of computing.

          The unit size of large computing platforms (i.e. mainframes) do not encourage such scalability. Multiple mainframes in a data center may increase data processing power at that central location but doesn't encourage a shift of computing power

    • IT needs some kind of an apprenticeship system or at lest more tech schools where you learn from people who have done real work and not so much people working on there academia papers and you have more hands on learning as well.

      • I meant this progression to be a "good thing". One problem with apprenticeships is that you reinforce the established way of doing things. Bringing people in from the outside, especially those who learned from others that read or write academic papers allows new concepts to be integrated with established practice.
        • But CS is not IT and people who do academic papers are type of people in IT who have been in academic for most of there life and have little to no hands on IT work.

          And we don't need more people in IT loaded with academic smarts but little IT book smarts / Little hands on smarts.

          • I'm not so sure that is entirely true. I do not believe data centers (at least the good ones) are complete void of CS people. IT people who maintain an infrastructure do not work inside a vacuum. They are either influenced directly by CS people within their organization, or indirectly by the computing appliances or applications that they maintain.

    Mr. Winestock's parallels between server farms and mainframes are reasonable, if unoriginal, and the same can be said for his concerns over privacy and social control. His attempt to claim the former as the causative agent for the latter, however, goes wrong right from the start: 'Mini/micro-computers were supposed to kill the mainframe.'

    Not so. They came about firstly because technological advances made them possible, and also because some smart people realized that they would allow us to do things that, in practice, we could not do before. The pioneers of these developments were not interested in reproducing, much less replacing, mainframe computing.

    Turing showed us that the form of our hardware doesn't dictate what we can do with it. To understand the arc of privacy erosion and social control, we need to examine social history and human nature, not the artifacts of technological advance.
