Dual Intel LAN NUC!



  • So after a fair bit of searching I finally found a NUC with 2 Intel nics!

    http://www.jetwaycomputer.com/JBC311U93.html

    I got a quote and it is only about $200 USD. I think this would make a fairly nice low power box. What do you peeps think?



  • $200 barebones will be closer to $265 by the time you have RAM ($39 for Kingston @ SuperBiiz) and disk (16GB m-SATA $26-$30) inside.

    and I see them for $149.95EUR (which is $190) here: http://www.minipc.de/catalog/il/1864

    Maybe the case is only $10, but you'll need a power supply.

    In a case, with a Power supply, they're 184.00 EUR, so $234.06.    Note you still need the RAM and a disk of some kind.
    Now you're at $299, and, frankly, in a few months, we'll be close to that price for 4 Ethernets on a C2358 platform (which has
    AES-NI and QuickAssist, and has an on-board e.MMC.

    Anyway, call it 'circulating around $300' with no AES-NI.  (Maybe VPN isn't important to you.)

    It's interesting though. There's a lot to like about it. It's small. It has Intel NICs. It has a wide range voltage input which opens up some interesting possibilities. It's very low power, be interesting to get some real power figures for it.

    Steve

    The C2358 (RCC-VE) platform also has better Intel NICs, and for approximately the same price as that NUC, you get 4 of them, and another miniPCIe socket (with SIM support).

    And then there is this:  http://imgur.com/EeLBavM

    It's small.  It also has better Intel NICs (i350 .vs 82574L), it wants 12VDC in, and if you can't provide that, you have different problems.  It's very low power.  It supports AES-NI.    It also lacks HDMI and audio ports (yuck on a router/firewall)

    In early 2Q15, it will be available at a similar price to the PC Engines APU.  (Note: it's related to the product you'll find on Netgate/ADI websites, but I'm talking about a spin.)

    This is what happens when someone who knows how to engineer solutions for pfSense software shows up.


  • Netgate Administrator

    Nice.  :)
    I do like to see a wide input voltage, mostly because I have loads of laptop power supplies and I'm a cheapskate. Also though with the cost of electricity rising ever higher I'm more seriously considering a small scale solar installation. I realise that's incredibly niche and it's also somewhat just moving the power electronics to different place in the system. I'm sure Phil would be pleased.  ;)

    have you considered he efficiency of your setup lately?

    Yes, and yes my home box was not the most efficient. It was around 42W. It died last week though and the replacement is ~25W so that's better but still not great.
    I'm torn between saving money in electrical terms and keeping old hardware out of landfill. Not necessarily rational.  ;)

    Steve



  • Actually, I think your choices are perfectly reasonable.

    25W isn't bad.  Unless electricity is crazy high price where you are, the cost benifit is in your favor.

    Plus, older hardware usually works better with pfsense anyway to be honest.

    Seems to me that usually when I pay premium for "bleeding edge" I'm usually just paying for bugs.

    I think my old athlon is burning 45w….

    I'm really really happy with my q1900dc-itx.  Its working quite well on linux but I think on pfsense it would be a different story probably.


  • Netgate Administrator

    Gone a bit off topic here but anyway…
    The real reason I'm running such hardware is for fun. My inner geek just loves to make some piece of hardware do something it was never intended to do.  :)
    Yes 25W is good but not great. Looks pretty bad compared to the Alix at ~5W. The cost of electricity is getting ever higher but right now the sums don't always add up. I would want to get pay back on new hardware within, say, 3 years. Seems reasonable? I could have swapped out my old box a long time ago but would it have been worth it. I'm saving ~17W, those are pretty rough figures though I'll have to actually measure the Wh over a week. That's ~150kWh a year. At 12.82p/kWh that's ~£20 a year. So actually over 3 years that would have paid off the cost of that box from Ebay.  ::)

    Steve



  • I'm same as you.

    The only reason I built that q1900dc-itx computer is because Its remote from me and my sons are super lazy about cleaning fans in cases, psu, cpu etc.  I also like that it will run directly off the DC of my solar without firing up the inverter.  Very efficient.

    I had an old athlon there but they let it die of dust and heat. )-:



  • (24 * 365 * 25)/1000 * .1282 = 28.07580

    (24 * 365 * 5)/1000 * .1282 = 5.615160

    The low-end C2K SoCs are 6W TDP, 10W system.


  • Netgate Administrator

    When I next upgrade it's not going to be driven purely by economics. It would take many years to pay off even the most frugal system. There are many other reasons I might do it though, the total and VPN throughput of that firebox is nothing special. With any luck I might need more than that soon enough.

    @kejianshi:

    I also like that it will run directly off the DC of my solar without firing up the inverter.  Very efficient.

    Nice. Care to detail your system? Are you running purely from panels and batteries or you have chargers, regulators etc?

    Steve



  • It has 2 100 AMP-hour deep cycle batteries with very low internal resistance.  Low loss on charging.
    300 Watts of mono-crystal solar cell.

    Uses a morningstar PWM charge controller.

    The computer runs straight DC off the batteries.

    The batteries stay at full charge.  In the event of a power outage a Xantrex Prowatt Sw2000 with a quick switching relay acts as ups.  It switches power fast.

    The system is very old by now.  I built it long ago.  Even the inverter is old and thats the newest part.  I originally used a modified sine wave inverter.

    That never failed but a real sinewave inverter is better for inductive loads.  It just keeps going.


  • Netgate Administrator

    @kejianshi:

    The batteries stay at full charge.

    So you don't run the machine after dark?
    I'm just considering what size batteries and panel I might need for a 25W continuous load and how long the payback might be on such a system. The biggest problem with solar here in the UK, even in the south, is that variation between summer and winter in Wh per day is huge.

    Steve



  • In hawaii I was able to run all my lights in my small apartment and only used a 100W panel.

    Less light in Maryland, so I use 3.

    You can size your battery, charger, inverter etc based stricly on the intended load.

    You can estimate solar panel need to be around 200w to keep the battery charged.

    You can add another panel if its not charging well.

    Its hard to estimate your available sunlight not being there.  Not knowing your available orientation to the sun.  Average shading. ETC.

    Knowing what you know about seasonal solar variation there, build and test it in the dead of winter.  Around Dec 21st – Winter Solstice

    Yes - The computer runs 24/7.  It barely bothers the batteries.  They recharge to full shortly after the sun is up.  Its drawing maybe 13w.

    I think solar is a great way to power low watt items like modem, router, switch etc.  If sized properly, its far more reliable than grid power.

    Pretty much guaranteed to never surge or spike or brown out if its all DC directly its especially reliable.

    So thats Maryland.

    Where I am now, in Manila, there is 4x as much solar radiation and electricity is 2.5x higher than USA prices.

    This is what we call a "no brainer".  I will build something here big enough to power the house completely.

    Steve

    Yes, Phil is pleased and happy that this niche is becoming more popular. My bigger offices would do well with 4-port devices so we can have 2 WAN/ISP connections and have 2 LAN (e.g. office LAN and guest WiFi system) without also having to add a VLAN switch. But want 12V DC and low-power to run from solar as much as possible.The links from gonzopancho look promising. It will be interesting to know what power the production boards use at or close to idle (which is most of the time) and when doing some real work, and also if they officially can take wide-range DC input (e.g. 10/11-15/16VDC) to connect directly to batteries that are being charged and discharged during day and night.
    Outside of Kathmandu we have to beg to get a 2Mbps link, so bandwidth/throughput/processing power is not our problem any time soon!



  • The q1900dc-itx is a nice computer.  I run it as the main linux machine for the house supporting samba shares, printer sharing, and as the media (Movies, music, pandora, hulu, netflix) machine that is hooked up to a large TV.  It simultaneously runs windows inside a VM to support a legacy printer/scanner.  It accepts voltage from 9v - 19v DC with a common barrel plug. I don't think phil.davis would want to use it as his router, but I assume he also needs real computers?  Its super low power and no fans to fail.  Mine runs super cool.  Around 27c for the mobo and 38 for the CPU.

    As far as the computer, http://www.jetwaycomputer.com/JBC311U93.html

    I like it OK.  Good enough for pfsense.  I like the HDMI ports because I prefer full installs with regular monitors and keyboards, mouse, etc.
    Abit pricey for my uses and not as fast as my current board but power use is lower so if you are on a power budget, might be nice.



  • Abit pricey for my uses and not as fast as my current board but power use is lower so if you are on a power budget, might be nice.

    Yes, more expensive, no AES-NI, and higher power than other solutions.

    But pfSense runs on it, so you can do what you like!



  • Howdy All:
    I was eyeballing an older Intel NUC –DCCP847DYE--Rather cheap at $150
    Only one LAN but it has 2 mini-pci-e. One full and one half sized slot.
    I want to build a nice low power pfSense MIFI and with 2 slots this will work.Half sized -Atheros/Full Sierra

    Q: Any other NUC's offer 2 mini PCIe slots in any form??
    I see the DC3217IYE as well but both are last generation QS77 and that one is more.
    Thanks Frank



  • Similar to _Rogue I was also looking for a pfsense wlan router with <10W, small and enough power to OpenVPN >50 Mbit (and in an ideal case 100MBit for the upcoming VDSL2 line) and ended up with the noted Jetway HBJC311U93W-2930-B and just replaced the internal half-sized intel wlan with an atheros version. And while rather early, the device seems to do the job.

    Regarding power usage: with pfsense 2.1.5, Kingston 60GB SSD, 4GB ram, network, HDMI and a Logitech K400 keyboard connected the jetways power usage is 8.5W when idle - wich is much lower than I expected with HDMI on.

    The other cheaper available solution I considered was the Mitac E220 based on the J1900 and dual lan (but no Intel NICs).

    Otherwise I agree with gonzopancho, if you have the time to wait, I guess there will be plenty of nice hardware coming up next year with AES-NI support to allow very fast VPNs in small devices with <10W. But isn't there always a better solution next year? And the HBJC311U93W-2930-B will still be usefull for other jobs (media player, …) once replaced.


  • Netgate Administrator

    8.5W is impressive. How are you measuring it? Do you have powerd enabled? Does it recognise such a relatively new cpu?

    Steve



  • So what did you choose for Atheros radio. I have a bunch and finally found a good half card.
    Dell Alienware AR5BHB112.
    Only Atheros 450M half card i could find.
    I bought the DC3217IYE to build a mifi hotspot.



  • I like that the Jetway uses wide range of input voltages. From 9V-24V. To me that is very versatile. I am guessing the intel NUC is 19V only?~??
    I will fire up adjustable power supply and test when it arrives. I am really hoping it works at 12V as i would like to incorporate a PicoUPS into my MIFI so i can carry it from the car to an outlet with a battery pack I want to build it with 12V-12AH SLA batteries and an plastic enclosure..I'm thinking lunchbox design with battery on bottom and the computer on hinged lid with a handle outside..



  • The 8.5W with pfsense 2.1.5 on the jetway HBJC311U93W-2930-B were without any additional power optimzations done. Just the default pfsense settings. I only did setup the LAN ports. But considering the old pfsense version and nor could I find any other data available online, I tried other systems incl. pfSense 2.2 (amd64-20141108-0611).

    Now let's summarize the idle power findings:

    pfsense 2.1.5 no tweakings:          8.5W
    pfsense 2.2   no tweakings:         10.0W
    pfsense 2.2   PowerD enabled:        9.7W
    ipfire 2.15   no tweakings:          8.8W
    ipfire 2.15 (powertop savings):      7.3W
    

    All tests were made with HDMI on and usb keyboard connected. Default A01 BIOS settings.
    Without HDMI/usb devices connected the above values are only further reduced by 0.2-0.3W.

    I am new to FreeBSD (do have Linux experience), but I really wonder what those high pfsense 2.2 values are causing. The CPU is rather idle and thus there is no process causing this. Any help/recommendation would be great as good non-obsolete info on powerd on FreeBSD seems hard to find. On Linux enabling the powersaving of usb/PCI/sata/audio as recommded by powertop reduced the consumption by 1.5W and with pfsense 2.2 there needs to be done more to become competitive.

    stephenw10: power measurements were made with a small old power  meter EKM 265 from ELV. The low power measurements in the past were pretty
    compareble to figures published based on a professoinal LMG 95 device from ZES. So they are unlikely completly off ;-)  I also did some measurents using a Fritz!Dect 200 wich provides 0.15W higher values on the jetway and allows displaying the power usage over time.

    Phishfry: I bought a noname Atheros 9280 card. I avoided the newer cards for now, as I allready would be lucky to get this one working reliable. I had my share of driver problems with atheros in the past on dd-wrt and OpenWRT devices. Never worked 100% reliable.

    And at last some openssl benchmarks results. During those tests the power usage increased by 2-3 watt. Sorry I had no tools for a quick max test. But based the Intel NUC measurements published, I guess with CPU and GPU maxed out you can get 16-17W - very unlikely values in routing practice wich should stay <10W if pfSense 2.2 power usage is optimized.

  • The only good way to measure power draw is with a amp meter…  On the cord that plugs into the wall or battery power.

    But I'm sure its quite low.

    I'd like to have one of the new atom 8 core boards but I'd run alot more than just pfsense on it.


  • Netgate Administrator

    My first thought is that the much newer drivers in 2.2 (built on FreeBSD 10.1) is enabling some hardware that 2.1.5 doesn't. Maybe the ACPI stuff is working significantly differently.
    It's a little old now but this is pretty much the definitive document in saving power in FreeBSD:
    https://wiki.freebsd.org/TuningPowerConsumption

    Steve



  • kejianshi: It's a True RMS based measurement at the power plug at the wall. So I do not know what is wrong with that other than the device not being as accurate as the noted LMG 95.

    stephenw10: I already run into the site you noted. But as said, I am new to FreeBSD and thus the note like "hint.ahcich.X.pm_level" is something I do not easily understand (like how to determine the X.Y devices on FreeBSD?). And shouldn't a PowerD configuration handle these things? So there are lot's of time consuming searching coming up to get answers.



  • There is nothing wrong with it.  Thats the way to measure it.



  • I have done some testing on pfsense 2.2 and I think the cause for the higher power usage is that the CPU is not switching to >C1 states on the jetway NUC. I already tried all sorts of things: disabling throttle+p4tcc, trying to set hw.acpi.cpu.cx_lowest="C3" and various P-State settings in the BIOS, but after booting hw.acpi.cpu.cx_lowest remains on C1 and no change to dev.cpu.0.cx_usage. Strangely dev.cpu.0.cx_supported does list C2/C3. No obvious problem reported in dmesg either.

    Being a FreeBSD/pfsense user for just some hours, I wonder if this is a limitation of FreeBSD on Bay Trail-M? A BIOS problem? A missing setting in rc.conf?

    Any idea what I could try next? C6 does work with ipfires Linux kernel 3.10 so it's not completly broken.

    Hmm, interesting.
    I have played with power tuning on a couple of boxes, both much older than this. A Pentium-M based box responded very well to powerd controlling the P states, 15-20% idle power reduction. However a C2D box much less well, though I was hacking the BIOS to enable speedstep etc which confused things.  ;) It appeared as though the lower power C states overwhelmed any gains made by using P states. On that box I had to enable the lower C states in the BIOS and then set the sysctl to allow a lower 'lowest' state. It's a while ago now but I'm pretty sure I set dev.cpu.0.cx_lowest rather than hw.acpi.cpu.cx_lowest.
    powerd can control a couple of other things but mostly does only CPU power control.

  • Thanks stephenw10. I tried everything. Switched to FreeBSD 10.1RC4 and generated the data necessary to file bug report 194920 on bugs.freebsd.org . Maybe they will fix this for FreeBSD 11.

    The additional 1.5W power this bug seems to cause on idle are less of a concern  to me as the pfsense 2.2 system is down to 9W with the noted settings. A bigger concern is, that this might be the reason for powerd being stuck to 1826 MHz and not getting into turbo with the openssl speed test running on one thread? For now, the speed should be more than fine for my 50MBit VPN. But with 100MBit this might become a problem.

    Forgot to talk about temperatures on the jetway NUC: CPU is usualy fine with <50C. It takes some time until the case warms up under heavy load. A bit concern gives me the mSATA ssd wich already has reached a max temp of 63C during the tests and it is not >40C in summer and heavy load for hours. Jetway seems to also have some suspicions for such extremes and did add a fan connector. But I guess a small heatsinks connecting SSD with the case will be totaly fine for me.

    My understanding is that the 'turbo' mode is not dependent on the OS, I don't think powerd is the issue here.
    Also I imagine that cpu will easily manage 100Mbps of vpn traffic even at the lower frequency.

  • I couldn't find any info on the Bay Trail turbo mode, but all info I found from Intel seems to indicate that C1 state is considered active when it comes to turbo mode and thus there is no turbo with all cores in C0 or C1.  If powerd doesn't display the turbo frequency even if activated by the cpu hardware, then I guess I have to find another way to test that.


  • Netgate Administrator

    The cpu frequency should be shown in the sysctls. I forget exactly which one, I usually just grep for 'freq'.

    Steve



  • I made a copy/paste fault while testing FreeBSD 10.1RC4 and unlike pfsense C2 (not C3) states are reached. This at least gave me an idea what might be wrong with pfsense 2.2 beta.

    My current guess is, that saving

    performance_cx_lowest="C8"
    economy_cx_lowest="C8"

    in /etc/rc.conf.local doesn't work on pfsense 2.2 beta unlike FreeBSD. The setting has no effect on sysctl output after reboot like on FreeBSD.

    I couldn't find any actual data on the net, but where do I have to save this if not /etc/rc.conf.local on pfsense 2.2? Maybe I should create a new thread on this as this doesn't seem to be jetway NUC related.

    I also run some benchmarks and the turbo mode seems to be working on pfsense/jetway NUC even if all cores are in C1. So all is well with the jetway NUC. Only the idle power usage is slightly higher compare to pfsense 2.1.5/ipfire…


  • Netgate Administrator

    Custom sysctl settings  can be added via the webgui in System: Advanced: System Tunables: that way they are saved in the config file and carried across an upgrade.
    However these are the equivalent of using /etc/sysctl.conf in FreeBSD. Hmm, not sure about rc.conf settings.  :-\ You're correct that these files are not used in pfSense as they are in FreeBSD, they are generated by the pfSense scripts using info in the config file.

  • Hi there,

    Im new to the forum and PFSense, I was searching for the forum for the
    Jetway NU93-2930 motherboard
    I didnt get any hits but searching for the CPU I found this thread. Rather than start a new thread thats basically the same
    I tacked on (Hope you dont mind)

    The board seems ideal, tiny, dual intel gigabit ,variable power requirements and CHEAP!

    I have just yesterday upgraded to 74/19 fibre and Im thinking firewall/virus protection and VPN

    Does the CPU in this little board of tricks have enough left for future tinkering?
    I use Bittorrent alot and intend to host a game server next year.

    EDIT: Im in the UK



  • Its max ram is 4GB - maybe not an issue but packet sniffing combined with packet filtering may take this to the top of the memory stack.

    "Shared mPCI-e slot" could be interesting for additional Ethernet

    power savings are huge with this "NUC" - this is put into a full box solution with JBC311U93E-2930-B priced at $220 barebones (CPU, power, wifi /BT included.)  Will have to boot off something other than a 2.5" sata drive.  No room in box or SATA header for 2.5" media.



  • Rexki, the Jetway is listed with 4GB max, but for instance on http://www.mini-itx.com/store/~JBC311W you do get 8GB DDR3 lp modules for it. Seeing similar offers for other N29x0 systems with single memory slots, I assume the CPU is capable of addressing 8GB with certain 8GB modules.
