HP's new ARM-based Servers
- atlbeer 15y agoHere's a good article summarizing the HP site which does a horrid job explaining what it actually is http://www.theregister.co.uk/2011/11/01/hp_redstone_calxeda_servers/ http://www.theregister.co.uk/2011/11/01/hp_redstone_calxeda_...
- sounds 15y agoI don't want to predict the future, but if HP thinks it can win over customers with 100% marketing and no technical details, that's not a good sign. I make the IT purchasing decisions for my company, and I know what an ARM CPU is, and why it's a good idea. Therefore, I know that HP's approach doesn't make sense: ARM hasn't been proven in this market. Therefore, customers and vendors (like HP) need to work very closely and there needs to be openness about design issues, performance tuning, etc. HP's starting off on the wrong foot. Maybe there's enough money in ARM that they'll figure it out. But if I have to make a prediction, I'm of the opinion the ARM server market is going to take off so fast that HP will be left behind.
- rbanffy 15y agoAsk them if they can lend you one that looks promising. Then run your workload on it and do some benchmarks. You should never rely on vendor-supplied data to make your decisions
- wmf 15y ago...win over customers with 100% marketing and no technical details... Hasn't the enterprise market worked that way for years?
- seltzered_ 15y agoThink of this as Calxeda/HP's minimum viable product in the ARM server market. Someone's gotta put something out there to get feedback. I wouldn't be surprised if they give some servers away to big enough companies in exchange for feedback on how to make deployment software going forward.

- scott_s 15y agoThank you, I looked at very link on the HP page, twice, and learned nothing about what they actually were going to sell. I googled "Redstone Server Development", and I found some more recent articles: http://www.crn.com/news/data-center/231902061/hp-intros-low-energy-data-center-platform-based-on-arm-servers.htm;jsessionid=8aRSxq6BiFttIw2hKAx+zQ**.ecappj02 http://www.crn.com/news/data-center/231902061/hp-intros-low-...
- antpicnic 15y agoHow odd that HP calls these servers Project Moonshot. A moonshot used to be slang for something with a low probability of success.
- lukeh 15y agoIt's also a federated authentication project for the non-web: http://project-moonshot.org/ http://project-moonshot.org/
- rbanffy 15y agoIt's against HP's immune system to sell machines without Windows. They already try hard not to sell their HP-UX and NonStop boxes, but clients insist on relying on them.
- endlessvoid94 15y agoHPs urls are terrible: http://h17007.www1.hp.com/us/en/iss/110111.aspx http://h17007.www1.hp.com/us/en/iss/110111.aspx
- lreeves 15y agoNo kidding. Clearly they're using IIS, which has the equivalents of mod_rewrite built-in. Why would they keep using such awful URLs? The only other major company still using cruft like that I can think of is IBM. Totally unnecessary.
- jonursenbach 15y agoAmazon is up there too. http://www.amazon.com/gp/product/B003O6G5TW/ref=s9_hps_bw_g63_ir01?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-5&pf_rd_r=13KXA06CD1CPTH1KGGVJ&pf_rd_t=101&pf_rd_p=801471022&pf_rd_i=14220161 http://www.amazon.com/gp/product/B003O6G5TW/ref=s9_hps_bw_g6...
- mbreese 15y agoAt least with Amazon, all you need is: http://www.amazon.com/gp/product/B003O6G5TW http://www.amazon.com/gp/product/B003O6G5TW Which isn't too bad...
- cpeterso 15y agoOr even: http://amazon.com/dp/B003O6G5TW http://amazon.com/dp/B003O6G5TW or: http://amzn.com/B003O6G5TW http://amzn.com/B003O6G5TW
- xtacy 15y agoGoogle too: https://plus.google.com/107117483540235115863/ https://plus.google.com/107117483540235115863/
- jonknee 15y agoThat's intentional. They'd rather not give out a bunch of Google Accounts usernames (which would also be a lot of Gmail users).
- jbellis 15y agoDoes it support ECC ram? None of the other ARM servers I've seen yet have.
- wmf 15y agoYes, it is a real server.
- deleted 15y ago[deleted]
- joshu 15y agoNo details or pricing whatsoever?
- stuntprogrammer 15y agoYou can get details on the underlying server architecture from Calxeda's pages describing the system on chip, and the quad server boards that are in the initial HP design: http://calxeda.com/products http://calxeda.com/products
- m0wfo 15y agoSeeing as it is neither enterprise software nor the fruit of an overpriced acquisition, Leo Apotheker must have been ousted before he had a chance to kill this project as well.
- dman 15y agoIs this another line of non-intel machines that the manufacturer will bury in a hidden portion of their website and deny that even exists in public?
- Donch 15y agoI think this is a highly significant move by ARM. It's amazing when you speak to datacentre people and they tell you how much of your server charges go on electricity and cooling. My recent example was £200 extra/year for an additional Opteron 6128 and £400 extra/year for the increased power usage from that processor! There is an obvious gap in the market for low power, low heat generating, high memory throughput server processors. I'd just like to see a reference Linux distro which supports 16 ARM cores as well as a reference server card... The specs: http://www.calxeda.com/products/energycore/ecx1000/techspecs http://www.calxeda.com/products/energycore/ecx1000/techspecs only refer to 32-bit memory addressing as well (ie. <4GB of memory). Seems like the wait will be for the ARMv8 64-bit processors to be integrated. Interesting times!
- ajross 15y agoNo virtualization ability. No addressibility of more than 4G is a killer for some apps. CPU horsepower density isn't quite as high as they say: at 72 quad-core A9's per rack unit vs. 6.4 Xeons in a comparable 10U blade server. A Nehalem clocks about 3x faster and runs about 1.5-2x faster per clock than the A9 for "random server logic" workloads, so this appears to be higher by only a little bit. Power consumption isn't clear. I see no peak load wattage numbers, which worries me for a product marketed expressly as a low-power option. One advantage this architecture does have is density of memory bandwidth. They have 72 DDR3 channels per rack unit vs. 25.6 for a blade server filled with 4-channel Westmere EXs (the Intel boards will stack the DIMMs up on the same channel). So you might want to look seriously at it as a hosting platform for a very parallel in-memory data store.

- lgeek 15y agoI'm going to guess that by 'no virtualization ability', you probably mean no hardware acceleration for virtualization. That doesn't mean you can't have OS-level virtualization. In fact, I'm working on a hypervisor for BeagleBoard. Plus, TrustZone has been hacked in the past to implement virtualization.
- trebor 15y agoI wonder if the Redstone part of the name came from a secret Minecraft fan at HP's headquarters. I hope it succeeds, just to give Intel a run for their money. I really think that ARM is the future of computing (including the desktop).
- ceejayoz 15y agoGiven the "Project Moonshot" bit, I'd imagine it's from the Redstone rockets that launched the Mercury astronauts into space.
- rovar 15y agoProject Moonshot? What's wrong, "Project Vaporware" was taken?
- antoinehersen 15y agoFrom the Register article: "The hyperscale server effort is known as Project Moonshot, and the first server platform to be created under the project is known as Redstone, after the surface-to-surface missile created for the US Army, which was used to launch America's first satellite in 1958 and Alan Shepard, the country's first astronaut, in 1961."
- jsn 15y agoFrom http://www.theregister.co.uk/2011/11/01/hp_redstone_calxeda_servers/ http://www.theregister.co.uk/2011/11/01/hp_redstone_calxeda_... : The sales pitch for the Redstone systems, says Santeler, is that a half rack of Redstone machines and their external switches implementing 1,600 server nodes has 41 cables, burns 9.9 kilowatts, and costs $1.2m. A more traditional x86-based cluster doing the same amount of work would only require 400 two-socket Xeon servers, but it would take up 10 racks of space, have 1,600 cables, burn 91 kilowatts, and cost $3.3m. Hmm, let's see. It's about 7-8 grands per Xeon server, something like HP Proliant DL360R07 (2 x 6-core Xeons at 2.66GHz). It's 3 times as many cores as Redstone, clocked at 2.66 times greater frequency each, and doing more instructions per clock tick, too. And that's without hyperthreading. Am I missing something big, or is Redstone solution neither cost-effective nor energy-effective?
- tmurray 15y agoYou assume the application is compute limited and that the extra performance on the Xeon translates into extra performance on a given application. That's probably not a good assumption for this kind of workload.
- jsn 15y agoWhy, for embarrassingly parallel workloads (like the ones they mention) it's a totally reasonable assumption. And for something not so parallel the gazillion of ARM nodes is all but useless.
- easp 15y agoThe article mentions Hadoop, big data crunching, web serving and web caching. They may or may not be embarrassingly parallel, but that doesn't mean any of them are typically compute bound. Look, today's multichip, multicore servers tend to be unbalanced for a lot of workloads. Their massive compute performance often burns power waiting for main memory, disk or network.
- miratrix 15y agoYou're going to be I/O bound (network or disk), memory bound, or compute bound. It's hard to imagine the Redstone systems besting Xeon based servers in any of the three.
- deleted 15y ago[deleted]
- lgeek 15y agoI find it strange that they're using Cortex-A9 CPUs. I would have expected anyone going for the server market with ARM cores to use Cortex-A15, which has 40 bit addressing with PAE.
- wmf 15y agoThe A15 wasn't available when Calxeda designed the chip.
- spydum 15y agoSo.. another blade server solution? I thought RLX tried this a decade ago, and went home bankrupt?
- wmf 15y agoRLX really needed scale-out software and DevOps, but neither was widely available in 2001. Also, Calxeda is claiming a larger advantage than RLX did. And wasn't RLX technically a success since it was bought by HP and then canceled?
- ricardobeat 15y agoJust yesterday I was dreaming of small server racks composed of Raspberry PI's and BeagleBoards. Wish I had a few million lying around… or a cheap dedicated link at home.
- zhemao 15y agoDon't forget some BeagleBones for good measure. http://beagleboard.org/bone http://beagleboard.org/bone
- checoivan 15y agoMost are overlooking the change in thinking with these servers. Think of servers with ARM processors in the pipeline which will come with 64+ cores, available for cellphones. The biggest problem in a datacenter is not space or processing power, it's energy consumption and heat dissipation. Walking into a datacenter gives you the feeling that the place looks empty with plenty space to fit 6x more servers. Today this can't be done because there's no capacity for more air conditioning to cool more servers in the building. Also, the way of processing has changed in the last years, for example with map reduce, which makes having many cores way more useful than a single server with a massive 5 ghz core. Actually today, many servers are IO bound, not CPU bound. There's exceeding cpu capacity. Think of having a server, with 64 ARM cores and and array of SSD's. This won't heat up as much as mechanical disks or today's cpus, with very small IO constraints due to SSDs speeds and far more parallel processing power.
- malbs 15y agoOur solution to infrastructure/performance problems which dates back a fair way is to simply throw more hardware at problems. Lately we are starting to hit a limit - a power limit. We are actually limited in the data center we use not by space, but by our power consumption, so we now have a pseudo KPI of "reduce our power usage". It's a good goal, but certainly not one I had ever contemplated. A (future) stumbling block is our reliance on x86. Would love to be able to move to ARM =\
- rogk11 15y agoA FusionIO ioDrive2 SSD card is 24W. Not huge but if you add multiple of these cards in a server, the power adds up.
- jwatte 15y agoI hope it has ECC RAM, as opposed to most competitors I've seen before (such as the atom based boxes)
- stuntprogrammer 15y agoYes; it's a properly server oriented processor, with ECC, fast interconnect, large cache, etc.
- shimon_e 15y agoHow much cooling do these racks need? It could be a killer sales point if these servers need no cooling.
