        The problem is more the apps, windows itself could probably be ported without too much trouble but most windows apps are likely to have code that makes x86 specific assumptions and are closed source so only the vendors can fix them.

        Emulation is an option but unless arm cores start performing a LOT better than intel cores of a similar power envelope that won't help much.

        MIPS and PowerPC. It ran competitively on most of these architectures, but the problem was always the missing third party software. If Microsoft just wants ARM servers for internal use, this wouldn't be a problem. Other people could probably manage too. Server software on Windows tends to be either written by Microsoft, open source, developed in-house, or provided by a small number of other companies. The first three mean it can just be recompiled. The fourth means that MS can apply some pressure to encourage an ARM port relatively easily.

        A lot of the win32 API makes stupid 32-bit-and-little-endian assumptions, so Windows hasn't been ported to any big endian systems (PowerPC and MIPS are biendian, and Windows ran them in little endian mode). The 32-bit assumptions are hacked in win64 by using an LLP64 model, which breaks the assumption that sizeof(void*) <= sizeof(long). This is not guaranteed by the spec, but since it's true for pretty much every platform in existence before Win64, a lot of people assume that it is.

        ARM is 32-bit and little endian, so userland Windows software should be pretty trivial to port. The only real difference you might notice is that ARM doesn't support unaligned loads, while x86 does (it's just really slow). An ARM OS can trap the exception caused by an unaligned load and emulate it, so even code that depends on it could work, just slowly. The only time you'll notice this in C code is if you are doing a lot of pointer casting - if the compiler can tell that it's an unaligned load, it will do two aligned loads, and shift-and-mask the results together. This is not exactly fast, but it's faster than an OS trap.

      • FYI: MS will now drop Itanium support after Windows2008R2
        http://en.wikipedia.org/wiki/Itanium#Software_support [wikipedia.org]

        "However, Windows Server 2008 R2 will be the last version of Windows Server to support the Itanium and Red Hat Enterprise Linux 5 will be the last version to support the Itanium.[14][15]"

    I can see myself using an ARM-based linux server in the home.

    If they get proper business support from some largeish vendor pushing out rack machines then that'd be great too. All the servers I admin currently run x86 from Intel. Saying that, when idling, they're not terribly power hungry; but arm boxes should be a lot better.

    Lowering power consumption is never a bad idea for your bottom line, as long as the performance-per-watt is acceptable. The first thing I thought was that it would be useful for larger clusters of machines if the performance isn't on-par with power6/x86 server chips. At the end of the day the deal breaker will be just how much performance you can get out of their server chips, which will affect what type of environment they're suitable for.

        Another advantage might be lowering the number of components. A Beagleboard would make a great low-volume server, except that it lacks any way other than USB for connecting disks and network adaptors. The same ARM core with the GPU removed and a couple of SATA and GigE controllers added would be a great SMB server platform. You could pop the OS and most apps in the flash and connect an external disk for served files. With the disk spun down, you'd be using under 2W for the rest of the system.

          Exactly.

          My previous server was 6, 7 years old when it became my server. It did the job nicely until the hardware broke down. The current server is not serving up files any faster (the 100 Mbit LAN is the limiting factor), it is not serving the web pages or sending/receiving e-mail faster (again the network is the limiting factor), backups took a little longer but that no-one is waiting for so that doesn't matter.

          My old server probably used less power overall, so it was better for my power bill even tough

    • x86 CPUs are beasts.

      I'm wondering how well an ARM multi-core CPU would do just serving up files off a RAID array? x86 quad-core CPUs are probably total overkill for that - and perhaps not worth it because of the power consumption.

      Yep, there's a market for ARM.

    • I am using an ARM-based linux server in my home.

      cowlark.com is run off a single SheevaPlug with some USB hard drives attached. This is: SMTP server (postfix), spam filter (spey), IMAP server (dovecot); web server (thttpd); Java servlet server (winstone, run in OpenJDK, interpreted. Yuck. No JIT available for ARM); my local news server (leafnode); my local DNS/DHCP server (dnsmasq); my local backup server (rsnapshot). It's also my main shell box for doing downloads and stuff.

      The whole hardware stack, UPS included, consumes about 18 watts, although this varies depending on whether the hard drives are spun up or not. Most storage is on a 64GB home-made SSD (4 x 16GB USB keys & RAID!), so it's completely silent.

      The SheevaPlug is a 1.2GHz Marvell ARMv5, with 512MB of RAM and 512MB of flash (which I'm not using). It cost me about 70 UKP. Unfortunately it's only got one ethernet port, so I've got way too much stuff hung off its single USB port --- and Marvell's USB hardware is notoriously dodgy. The new GuruPlug looks way more exciting: same processor, but two ethernet ports, more USB ports, and SATA!

      I have a Marvell openrd-client. This thing has the guts of a Sheevaplug except it comes in a fancier case, uses a separate wall wart, has onboard video, more peripherals and a spot for a 2.5" hard drive inside.

      I've got a 500GB 5400rpm hard drive poked inside and Debian Linux installed, and it acts as a file server, music server, torrent downloader, etc. Pulls about 8 watts from the wall, though I've got video disabled, second ethernet disabled, etc. Couldn't be happier with the thing.

          I'd say that ARM is on par with x86 Hz vs Hz, or even better. The problem is that ARM is barely past 1 GHz while x86 is pushing towards 4 GHz. There are just now ARM processors with two high performance cores, while x86 processors are pushing past 12 cores and climbing. There are no ARM cores that I know of that does hyper threading, while almost all x86 cores do at least two way multithreading.

          So.. I'd say that we will be using x86 for high performance servers for quite some time still.
          However.. putting litterally thousands of low performance ARM cores in a 3U enclosure would certainly be good for some server applications.

              Generally speaking (at a very gross approximation!) the biggest factor in speed seems to be feature size, and ARM cores run cooler than x86 cores. ARM have focussed on the low-power end of the market far more than Intel and AMD (who have been duking it out at the high-speed end) and this means that for some applications, their stuff is absolutely best. I don't know whether that's true for server-class computing; the lower power consumption will get better packing densities but whether that will compensate for the reduced computational power I just don't know.

              Of course, a good benefit in the "small server" market would be being able to run normal workloads without active cooling (i.e., fans) in a normal room. That would save loads on power and aircon. (And I know for one thing that there are ARM cores that can cope with very wide temperature variations. It's impressive when you see someone torturing a CPU with a hairdryer and – straight after – some dry-ice...)

              ARM cores have both cache and pipelines, y'know? But lets find those benchmark results by making them ourselves:

              Using one core on an AMD X2 2,8GHz and an ARM Cortex A8 core at 600MHz on a beagleboard, I've done some tests. Cache-optimized matrix multiplication of two matrices at 600x600 takes 0.45 seconds on the AMD, and 4.57 seconds on the A8. That's about 10x slower. However, the A8 (in an OMAP3530 package) produces just under 1W of heat. The TDP for the AMD is 65W, but since it's dual-core let's take half of that, plus an additional 20% fuzz factor because the TDP is the maximum rating.

              By this slightly fuzzy, synthetic but memory-heavy benchmark, the performance-per-watt difference is about 2,5x in favor of the ARM Cortex A8 core. One core of an AMD X2 would have to put out below 10W to beat the A8. By my fuzzy math that would mean a TDP of 25W or below for the processor.

              There you go, you're welcome! :)

                Once you start pushing the performance envelope with the ARM core, your performance-per-watt advantage will become less pronouced.

                The ARM processor looks so good in your benchmark because it is really not asking much of the silicon at all. Increase the ARM processor's clock rate to 3ghz, and you will need to add:

                1) More cache to prevent memory core starvation
                2) More voltage to make the silicon transistors switch faster.

      I know that one of the original developers of the ARM CPU is working on a massively multicore ARM-based project (tens of thousands of cores). Apart from just the low power aspect of ARM, what makes it good for hugely multicore projects compared to x86 is that an entire ARM core is smaller than just the part of an x86 processor that figures out the length of the next instruction - x86's ISA becomes a huge ball and chain if you want to make a massively multicore system.

If we're still going to depend on x68 in 20 years I'd rather kill myself by banging my head against an x86 chip.

        Thing is, quite cheap and rather small laptops based on Intel CULV chips showed up recently; some of them certainly can do 10h, perhaps there are some with 12h. And they are fast, if needed.

        On top of that, if I look at announcements of ARM netbooks - even though they will be purposely quite limited machines, it doesn't appear like manufacturers want a price reflecting that. Certainly not as long as there's not much competition yet, as long as they can offer it as a "premium" machine. Which has a big chance

      Of course, you can spin it another way. ARM is an IP company - they don't make chips, they make IP (their architecture specifications, and their CPU designs) that they then license to other companies. Then again, they're not a patent troll, their IP is generally fairly good (even if the various architecture versions and features are ridiculously confusing,) and they actually do license it, rather than just keep it so they can sue people.

      • They also usually license designs rather than just ideas.

        The architecture licences (to Intel and others) may be exceptions.

    • s/anti establishment/shoestring budget and you are correct :-)
      ARM nowadays is a big company but originally it was a sidedevelopment for the next BBC machine.

      • I used to run MS-DOS (*) in the x86 software emulator on my 4-8MHz (**) ARM2-based BBC Archimedes in 1987 - some people then refused to believe this was even possible.

        (*) MS-DOS 5.2 IIRC - I needed the TopSpeed Modula2 compiler for my programming assignments & WordPerfect to open some docs.

        (**) 4 MHz when reading ROM, 8 MHz when reading RAM (there was a command to copy the entire ROM into RAM in Arthur 0.2/RISC OS 1.2)

          Although my post did not mention it I was thinking of where it was *invented*. AFAIK the 8086 was created by Intel in the USA. But I could be wrong :-(

    After many years, Intel finally has some challenge. And for those of you who doubt what ARM chips are able to do, I'll tell that I've been surfing the web and chatting through MSN Messenger on an Acorn A7000+, which runs on a 48 Mhz ARM 7500FE. Now, if they can raise that to 2ghz, I see very nice performance while still retaining a fairly low power consumption.

    As the cost of energy continues to rise (due to purely political reasons rather than any actual scarcity, which is sad) there's going to be more and more demand for computing equipment with low power consumption. ARM fits that requirement nicely ... and it's all going to be running Linux, even if Microsoft enters the game.

    Why?

    Windows running on ARM would suffer from the same (imho perceived) problem that desktop Linux on x86 has: it wouldn't be able to run Windows x86 binaries. In fact, for Microsoft it would actually be worse because they'd have to deal with irate customers who thought they'd be able to pop in that CD and install some application they already own.

    Linux has been playing this one well by establishing a large base of open source software that can be built on any platform. Combine this with your favorite APT or YUM repository and what do you get? The equivalent of an "app store" which is something the world is now quite familiar with. Linux for the win!/p?

    ARM currently supports 4 GB of memory since the ISA is 32-bits. Full 64-bit addessing support is years away. Interim "PAE" extensions will be just as ugly and unused as the x86 PAE.
  • I'm a bit disappointed that this is coming to pass, as it was a venture project I wanted to possibly get into at some point. I saw the potential, but obviously someone else did, too...

    Thus, I might be able to have ARM servers. That excites me. Thermal and power issues at the data center have always been an issue, as I'm sure they have for everyone.

    And realistically, many (if not most) systems don't need the power of a multicore Xeon server. I've got older P4 era infrastructure systems which barely even see

  • I'm already running an Arm based server. It's called a QNAP NAS and the TS419P runs a Marvell Feroceon CPU "Feroceon 88FR131 rev 1 (v5l)" (cpuinfo).

    It's running Debian Lenny (2.6.30-2-kirkwood) and thanks go to the Debian Arm team and Martin Michlmayr. Runs great.

      I too would like to thank Martyn.

      I used to run two NSLU2s, now I have a sheevaplug. His work enabled me to turn them all into debian boxes.

      How is the QNAP stuff? What's the core speed/RAM?
      Was toying with buying one but they were expensive compared to sheeva. Of course you have to get the disk caddy extra for the plug.
