There will be unrelenting pressure on cloud service providers to use the most energy efficient architectures. To fail to do so will be terminal to their long term plans. Most of them already know this and are watching the low power race with keen interest. Charlie Babcock, editor at large, InformationWeek
We need to stop confusing low power with energy efficient. If a system runs a job at 50W for 2 hours it is NOT energy efficient vs. a system that runs the same job at 100W for 30 minutes. That's where we are on microservers vs. servers.
Unit cost $54, and that's just the CPU---the complete system will require a chipset, whereas ARM tends to be a more integrated SoC requiring less components.
That says it all.... they aren't really interested in microservers.
Isn't it a SoC? There is no chipset listed in the specifications of Quanta STRATOS S900-X31, http://www.qsscit.com/en/01_product/02_detail.php?mid=27&sid=155&id=156&qs=94. Quanta QCT claims less than 10W per node.
Intel leap frog an over statement?
Whether 32 or 64 bit ARMS on blade is viable high margin business and can compete with Xeon with system management.
And it’s not issue of wimpy ARM, but crippled ARM given architectural enhancement that can make a StrongARM. ARM architectural license is advantageous over design license.
ARM community places scalar ARM at ½ perf of Intel dual issue. ARM 64 bit super speculated closing processing gap on freq v ATOM.
Seven 32 bit ARM 1.1 GHz quads equal one Xeon 2620 hexa 2.0 GHz in this Intel loaded molecular docking benchmark; http://www.lowpowerservers.com/?p=141. Need to email reviewer because it’s not clear how many Calxeda quads were thrashed in loaded benchmark verse dual Xeon 2620’s. And how likely does Vina code for molecular docking require FPU?
Xeon 2620 sells for $410 in 1,000 unit quantities. Not taking into account added system blocks that are BSM, I/O, NIC, Calxeda silicon is then valued at $59 which flies under Intel average fixed cost. But wait, might those Calxeda quads running 55% the frequency of 2620 be valued at $114? On hexa core equal basis $171? With BSM, I/O, NIC $198 placing Energy Core at Intel average total cost. Meaning there is a value message here for ARM SOCs that is not getting through.
For multiple ARMS on blade analyst suspects will reach into high end XEON product performance and price rungs.
Subsequently dual core ATOM S1200 presents solely low power paper tiger. Octa ATOM on low power multi core seems more likely an Intel barrier to protect higher power Xeon product and price voids certainly into E3, into E5 & even 46xx for massive dense where ARM NIC in SOC across fabric in VM mode is aimed to resolve Xeon power utilization issue. And what about ARM 64 bit sporting 12 and 16 cores v Intel?
ARMs on blade is a viable high margin business.
Yes, the ARM should be consider as high margin business, especially when you take the performance/dollar into consideration.
It seems would take 7 EXC-1000 to compete the E3-1220L v2 (17w, 189$) in apachebench (the ideal case for microserver). So, it seems it take 400$ for ARM server to achieve a 189$ Xeon server's microserver friendly workload.
What a nice margin:)
Calxeda's marketing lead notes that Intel's 6W Centerton has only two cores and lacks support for Ethernet, Serial ATA and a fabric.
But then Calxeda's ~4W four-core chip lacks support for 64-bit addressing which is a must for most server apps.
Why is 64bit a must for server apps? Do most server apps require more than 4Gb of memory?
I suspect that this '64bit is must for servers' is a received wisdom we accept because with Intel x86 processors, 64bit doubles (or better) performance. I suspect a lot of that is the extra registers available in X_64 mode. ARMs don't suffer the register starvation of x86 in 32bit mode, so the performance increase going to 64bit will be less compelling that for x86.
There's no one in the connected community denying 64 bit is not a prerequisite for commercial server.
Every ARM silicon and system design producer agrees with the 64 bit observation and you're aware those 64 bit developments are underway.
So how about an investigative report on ARM server progress at current 32 bit boot strap aimed for 64 bit growth?
The industry could sure use some independent design producer successes that enable unique and differentiated product utilities, supporting innovative use models adding margin values for the greater good of the business.
With Intel executives positioning to take out half the industry, isn't it time to support adoption of components and platform designs beyond a monopoly that now blatantly threatens to destroy the industry by concentrating out competitive innovation?
Surely some silicon, system, software, data center types could fill us in on the development chains perspective.
There is currently software systems integration addressing 32 bit implementations for NAS, home, small work group and slim work loads that Intel does not address.
This current quarter happens to be the E5 26xx volume peak, at approximately 20 million units, so why get 64 bit dumped on now?
Think integrated value.
By the way that’s 7 Calxeda quad to every Xeon 2620 hexa which is not crippled 1220L v2.
Considering El Reg, Calxeda, Apache benchmark.
No one in ARM silicon & systems wants to be compared within Intel sales paradigm.
ARM server offers unique utility benefits that define ARM server purchase requirement. That means no industry standard Intel benchmarks including Intel SPEC and Intel Hadoop.
ARM silicon in systems address a different paradigm that requires measure’s which truly document that environment's unique performance requirement; whomever the innovative benchmark author that addresses this benchmark product void.
Calxeda has systems at Apache which I suspect are addressing the utility benefit of ARM server.
This analyst is aware of others validating in wholly unique & differentiated app environments.
On El Reg; yes 32 bit ARM use model is 1 GbE.
Adopters with 1 GbE networks call an ARM server system’s provider today.
Adaptors with 10 GbE requirement call ARM Silicon solution provider for designing your very own. System design producers are addressing the requirement which can be advantageous for savvy innovator adaptors. Don’t forget there's Marvell and Applied Micro too.
On Calxeda Energy Card; four 1.1 GHz quads, BSM, I/O, NIC, storage at 11.56w v E3 1240 quad 3.3 GHz, 8 MB L3 at 56w under partial load:
Calxeda operation at 1/3 frequency, cool.
4 times cache & 1/2 code density, yumm.
4 to 7x lower power advantage according to Intel, intriguing.
40% better 1 GbE performance v Sandy E3 1240 quad 3.3 GHz, 8 MB L3, 80w TDP at $250 each and that's just the processor.
500% better 10 GbE performance v Ivy E3 1220L dual 2.3 GHz, 3 MB L3, 17w TDP processor at $189 each and 35w system power are discontinued. Never made the channel but if you want 1220L Intel might be able to reserve some from dice bank on their way to the crusher.
Does that mean the package costs extra?
please, really read the article. It's the comparison between EXC-1000 and crippled E3-1220L v2.
And by the way, it's 1 Exc-1000 performance as 1/7 of XEON. And only in the perfect scaling case can 7 EXC-1000 sacle up linearly and match 1 E3-1220L v2. This can (if possible) only happened at certain work load and certain situation(Apache, Mapreduce?) and without any software overhead. And don't forget the cost and energy to connect 7 CPUs are not ignorable.
The S1200 has a significantly faster clock and more HW thread contexts than its ARM competition; the former almost guarantees that the S1200 will have a higher TDP than the slower clocked A9s.
Can the ARM vendors describe their NEON implementation and how its stacks up to SSE3? Can they show us how their microserver cores perform on SPEC2000/2006 FP and INT? Can they tell us which toolchain developers can use that can match Intel's toolchain?
Interesting, though they might refuse to acknowledge, because of ARM they are forced to innovate and bring out low cost solutions to server market which are also performance competitive. This is going to cannibalize their Xeon share to an extent which again they wont admit. With ARM it is not just raw performance that matters, it is that their is a good alternative for businesses who cannot afford an Intel SOC for their server requirements.
ARM is here to stay even if it will not win the war.
