What Web 2.0 Means for Hardware and the Datacenter 125

Posted by ScuttleMonkey
from the driving-the-bottom-line dept.
Tom's Hardware has a quick look at the changes being seen in the datacenter as more and more companies embrace a Web 2.0-style approach to hardware. So far, with Google leading the way, most companies have opted for a commodity server setup. HP and IBM however are betting that an even better setup exists and are striking out to find it. "IBM's Web 2.0 approach involves turning servers sideways and water cooling the rack so you can do away with air conditioning entirely. HP offers petabytes of storage at a fraction of the usual cost. Both say that when you have applications that expect hardware to fail, it's worth choosing systems that make it easier and cheaper to deal with those failures."

        The big companies are locking on to 'Web 2.0' as a moniker for embracing an idea they had been completely ignoring until Google took advantage of it and forced everyone to notice. Smaller companies had already gotten the message that while hardware-failure tolerant servers have their place, in many situations with large numbers of systems the only practical place to solve it is in software, and then expensive hardware redundancy is superfluous, costing both initial money and additional power/cooling.

        I'm not saying Google was by any means the first to think of this or do it, but no one else that did that as part of their core strategy had come to the spotlight to the degree Google has. Every single one of Google's moves to the industry at large has become synonymous to 'Web 2.0', and as such hardware designs done with an eye on Google's datacenter sensibilities logically become 'Web 2.0' related. You'll also note them saying 'Green computing' and every other possible buzzword that is fashionable.

        Of course, part of it is to an extent trying to create a sort of self-fulfilling prophecy around 'Web 2.0'. If you help convince the world (particularly venture capitalists) that a bubble on the order of the '.com' days is there to be ridden, you inflate the customer base. Market engineering in the truest sense of the phrase.

          Unfortunately, there is one single definition of "Web 2.0", and that is the one of the guy who registered that trademark: Tim O'Reilly.

          Now I'm not usually one to make a big fuss over using a word wrong, but this one is actually a trademark. Deciding to use it in any other way, is a bit like deciding to call my Audigy 4 sound card a GeForce or an Audi. It just isn't one.

          And the extent to which both tech "pundits" and PHBs use it wrong, while (at least the latter) proclaiming their undying love and commitment to it, just leaves the impression that they use it as yet another buzzword. You don't proclaim your commitment to a technology, unless you actually understand what it is, how it can help you, and preferably how it compares to other technologies to the same end. Just going with a buzzword because it's popular, and ending up pledging your company to the camp of such a buzzword, is as silly (and often has the same effects) as making it your strategy to use scramjets in bicycles. Just because everyone seems to love scramjets lately, and you wouldn't want your mountain bike company to be left behind.

          To get back to the actual definition of that trademark, it's not even about technology as such. It's about people. It's not techno-fetishism, as in liking cool new technologies for their sake, it's techno-utopianism: the mis-guided belief that you only need to give more internet tools to a billion monkeys, to get a utopia like nothing imagined before. Although said monkeys never created anything worth reading with a keyboard, if it's keyboards connected to the Internet, now that's how you hit a gold mine.

          O'Reilly's idea is sorta along the lines of:

          - forget about publishing content (e.g., hiring expensive tech writers and marketers for your site), it's all about participation, baby. Let users write your content. Hust put in some wikis and forums, and a thousand bored monkeys will do the work faster, cheaper and more accurate. (People will just flock to offer you some free, quality work, just because they like donating to a corporation, I guess. And if instead you discover comments about how much your company sucks, the CEO's sexual orientation, and his mom's weight, well, I guess it must be true, 'cause collaborative efforts can't _possibly_ be wrong.)

          - forget about setting up your own redundant servers or dealing with Akamai, use BitTorrent. (Ask a lot of people how they felt about Blizzard's going almost exclusively through BitTorrent at launch. Nowadays their own servers serve a lot more of the content, if not enough other users are stuffing your pipe. I wonder why.)

          - forget selling media on the Internet, teh future is Napster letting people pirate it, like happened way back then. (No, literally, the "mp3.com --> Napster" line is part of his own page explaining Web 2.0. I guess good thing noone told Steve Jobs that.)

          - forget content management systems, use wikis. (I wonder in which alternate reality the piss-poor search engines of wikis can be compared to the capabilities of those systems.)

          - for that matter, forget about structuring information in any way, like through directories and portals, just let the users tag it. (I'm _sure_ that the tags "humor, theft, oldnews, !news, digg" will so help me find the story about a manager stealing the server from earlier. Never mind that search engines were already dumping searching for tags, in favour of full text search, even at the time when he came up with that idea.)

          Etc.

          Basically, if you have the patience to sift through his ramblings, and don't give up at the "well, Google started up as a web database" intro, the meat begins at "Harnessing Collective Intelligence". That's what's it about. It's not as much about what technology you use on the web, it's about connecting a billion clueless monkeys, and believing that the result is something a billion times more intelligent and informed. Anything that helps connect those monkeys is good, anything else is irrelevant. Even whether you us

      Web 2.0 is about a thousand layers above hardware, it does not in any manner, approach.

      Not to be pedantic, but it depends on what model you are using. According to the OSI model, the Application Layer is 6 layers above the Physical Layer. And according to the TCP/IP model, the Application Layer sits 4 layers above hardware.

      Network models with thousands of layers?! Not only is that crazytalk, it's way too precise to be practical.

      Actually, I found this part interesting, from HP's offering:

      When drives or the fans in the disk enclosures fail, the PolyServe software tells you which one has failed and where - and gives you the part number for ordering a replacement. Add a new blade or replace one that's failed and you don't need to install software manually. When the system detects the new blade, it configures it automatically. That involves imaging it with the Linux OS, the PolyServe storage software and any apps you have chosen to run on the ExDS; booting the new blade; and adding it to the cluster. This is all done automatically. Automatically scaling the system down when you don't need as much performance as you do during heavy server-load periods or marking data that doesn't need to be accessed as often, also keeps costs down. [emphasis mine]

      I know, not what you meant, but a funny coincidence.

      IBM is offering a more optimized rack, with shared and optimized power supplies, different arrangement for the fans, a heat exchanger in every rack for your building's air conditioner, (which Tom's interprets as water cooling) and a couple other things.

      HP has a weird clustering software/hardware hybrid with large amounts/density of RAID 6 storage (for a flickr-style site, for example) together with a cluster of blades that can all access all the storage and can be added/removed at will. Interestingly they point at scaling down the system when load is low, to keep the costs down. I wonder if they put servers on stand-by automatically or something. They are also looking at not spinning all the disks all the time, but they're not there yet. I guess having some disks acting as a write cache could allow you to at least spin down the parity disks of the LRU sections or some such. You could even cache the read side if you're willing to put up with the spinup delay on a cache miss.

      Supposedly this is Web 2.0 because you want a google-style cluster with lots of generic hardware where any one computer can go down and the whole thing keeps going. IBM wants to lower the maintenance costs, HP didn't show them the server side, but pushed their storage technology.

        3. processing power

    The best way to organize your serverroom for web 2.0 compliance is by stacking the servers diagonally. This way, air can float freely between racks, improving the flow of the system administrator gas based bowel attacks.

    Don't bother with those 10Gb switches, just hook it all up on wireless. Wireless network, wireless fibre storage, wireless power! Your megaflops (the rate at which a million projects per second will turn out to be a flop) will increase by a factor of 213% per watt.

    Web 2.0, the best thing to happen to your serverroom since buttered toast and angry system administrators, can be yours now only for $ 9999,95 per diagonal server! Why go for a 1U server when you can have a 2U for three times the price. Call now, and receive a free "My other server is a web 3.0" bumpersticker which will be applied by an angry salesman who'll also slash your tires for FREE!

    Warning: servers may not be stacked diagonally on top of eachother, rather rammed into your rack repetetively by an angry monkey (which we've nicknamed "Bob the technician"). Aforementioned technician may or may not leave presents in your servers. Do not feed Bob during the installation process, nor introduce Bob to small children and pets.

    To stop the web 2.0 discussion and focus on something interesting. From TFA:

    If you're an IT administrator for a bank and want to build a server farm for your ATM network, you make it fault tolerant and redundant, duplicating everything from power supplies to network cards. If you're a Web 2.0 service, you use the cheapest motherboards you can get, and if something fails, you throw it away and plug in a new one. It's not that the Website can afford to be offline any more than an ATM network can. It's that the software running sites like Google is distributed across so many different machines in the data center that losing one or two doesn't make any difference. As more and more companies and services use distributed applications, HP and IBM are betting there exists a better approach than a custom setup of commodity servers.

    Then they go on to talk about how google uses custom power supplies, how people are now charged by power consumption and how blade style servers use up too much power (?)

    They mentioned preconfigured linux servers for cheap, to help people avoid the extra work in setup (?)

    Etc. A jumble of suggestions for cheaper data centers, cooling many midrange servers, and so on.

      If IBM think youy have enough money, IBM will ram mainframs down your throat. This is for the people who want a green datacentre but for who System Z might be a little out of reach.
  • They cool their servers from the bottom to the top. Also sideways, so kinda diagonally, but they're getting excellent results. Sounds like an efficiÃnt idea to me. http://www.ibm.com/systems/deepcomputing/bluegene/ [ibm.com] And why don't they use Western Digital GreenPower drives? They have an enterprise version of those don't they?

    They mention 'sideways', and I thought they just meant rotating about the depth of the rack (ie, so a 19" rack would be about 11U wide), but the discussion is talking about the fans being 15" away vs. 25" ... which makes no sense, as they're mentioning servers being 47" deep. I think they're talking about side venting, which is what Suns _used_ to have, but you'd have to get these 30" wide racks (so there'd be ducts on each side for airflow in/out)

    And we have the useless quote:

    "In a data center the air conditioning is 50 feet away so you blow cool air at great expense of energy under the floor past all the cables and floor tiles," McKnight said. "It's like painting by taking a bucket of paint and throwing it into the air."
    I'm not going to claim that forced air is more efficient than bringing chilled water straight to the track, as it's not -- but the comparison is crap -- anyone who's had to manage a large datacenter will have had to balance ducts before -- it's not fun, I admit, but you don't just pump the air in, and expect everything to work.

    Then there's the great density -- 82TB in 7U. I mean, that's not bad, but the SATABeast is 42TB in 4U (unformatted), and I'm going to assume a hell of a lot cheaper. (although, it's a lower class of service). And HP's not using MAID yet, but spinning all of the disks.

    My suggestion -- skip the article. It reads more like a sales brochure, with very little on the actual technical details of what they're doing.
    • If they are water cooling, then not having the servers stacked vertically would keep you from frying everything below the one that springs a leak.
      • The servers are stacked pretty much like they have been before, but not as deep. The water cooling is contained within the door and does not go to the servers (as the article says, they thought that currently that was too pricey to be worth doing). Besides, they left their options open, it's easier to tack on a door or not based on the datacenter use of chilled water or not than it is to change system heatsinks, etc etc.

      Most racks are on the order of 2 ft. wide and 4ft deep. The iDataplex racks are 4ft wide, and 2ft deep, with two columns each 19" wide. The cooling is still front to back with 19" wide servers, it's just that the racks are less deep. They are doubled up presumably to be in some way conventional for shipping, marketing, whatever, but ultimately aren't as exotic as some would fear. They could have just as well had 'normal' 42U racks with only half the depth and logically be analogous. They also take some of the spare horizontal space and carve out 16U of vertically oriented U space.

      As to the air cooling aspect, I think the discussion is tilted toward the extremes of bad datacenter design to sound better, but water-cooling is more efficient to pump the distance even with clear path for the air to go. Not saying this is specific to any particular vendor (the difficulty of sticking the converse of a radiator on the back of a rack seems like it would be low), but I think IBM is fishing for ways to take advantage of two-column racks in a remotely meaningful way. In this case, the ratio of usable surface area on the water pipes to unusable plumbing in the design is higher since they can be wider.
  • I've always wondered why don't they just place the servers in places where it's cold all the year, imagine how much power they could save by using ducts to distribute the cold air from the outside in the server room. I mean, a solution like this can't be that hard to implement!

    This seems like a good opportunity to mention the famous Web 2.0 FAQ by Rich "Lowtax" Kyanka on somethingawful.com. For those readers who are not entirely sure what web 2.0 is:

    Question: What is Web 2.0?

    Answer: Web 2.0 is a combination of Web 1.0 and being punched in the dick.

    Question: How do I know I'm using a website / service / product that is officially "Web 2.0" and not actually "Web 1.0" with various patches and enhancements added to it?

    Answer: Web 2.0 is made obvious by the addition of completely and highly unnecessary bells and whistles that don't do anything besides annoy you and make life more complicated. If Web 1.0 was the equivalent of reading a book, Web 2.0 is reading a book while all the words are flying around and changing pages as the book rotates randomly and sets your hands on fire. Also there's this parrot that keeps on flying towards your head in repeated attempts to gouge out your eyes.

    Question: I read about this one website in Wired Magazine. Is that Web 2.0??

    Answer: Oh definitely. Wired won't even mention Web 1.0 sites. Every single site in their magazine is at least Web 2.0. Sometimes they're even up to Web 45.2 (such as www.ebutts-and-credit-reports-delivered-via-carrier-pidgeon.com)!

    Question: My roommate said he "digged" a "wikipedia entry" about "the blogosphere" which mentioned "podcasting" as a viable form of "crowdsourcing."

    Answer: Your roommate is a faggot. Also, this wasn't technically a question.

    Question: What's Web 3.0?

    Answer: It's a product or service planned on release in spring of 2008, and consists solely of websites enabling the user to create even more detailed Kirby ASCII art. (O'.')-o

    Web 2.0 really has nothing to do with 1u, or 2u servers being configured in any specific manner, nor the layout in the racks to be "sideways", upside down, or water-cooled. Web 2,0 is about moving the complexity required to support an application from the physical hardware into the application stack. This happens when an application provider builds resiliency and redundancy into the application and then the application utilizes the compute power of a series of systems merely as a process station. If a node goes offline, or fails, the application moves to the next logical set or online node. This really is nothing new to the industry, other than the capability now being available in the x86 platform. The hardware provider that will win in this space will be the provider that can build, design, and architect the highest possible compute spec while utilizing the least amount of both space and power. It's not virtualizing applications, or operating systems. It's about squeezing as many processing units into the smallest amount of space while utilizing as little power as possible and the application being architected in a manner that will utilize that. Gone are the days of needing to build fault tolerant hardware platforms, with back-up power-supplies, clustering,etc. Today we have smart applications that see that additional processing power is required, or that a process node is down, and the application fails over to the next node in line. This is really not new, what's new is the capability being available in the X86 space. that's a beautiful thing. that means the customer/consumer wins.

      So, basically all we're doing is taking some mainframe tech and moving it to x86 servers. Add in some hardware-based virtualization (say, to run old code on different physical processor technology), mix it with virtualizing the rest of the hardware, and give it a proper hypervisor and you have....

      A Z9 mainframe.

      Maybe IBM should just make some nice REALLY low-end mainframe-type PC servers with a "clustering" port.

      Mainframe tech is great, except it's just too damn expensive, especially when you're not doing enterprise-level data crunching.

      • Essentially that is dead on the mark.. add to it that companies like Google, Microsoft, and Salesforce (and others) are leveraging this capability to deliver both applications and services that leverage this technology. It's cool stuff, and really is the next "big thing" in the industry. Imagine having access to all your data and applications from any place, on any device, anytime. This is where we are heading technically..

  • Why not use mineral oil as a coolant? It has been used in transformers and other electrical applications to years. If it leaks, it won't do a whole lot of damage to the equipment or cause deadly electrical shorts.
