Selfmade NAS: Intel D510MO DualCore Atom as silent Storage Server

I frequently run out of space and since notebook times have arrived, i was always shocked about the bad performance of external usb storage. With luck, i get around 10 to 12 mb/s.
That leads to eSata or FireWire, but you pay like twice, or at least a 50 extra just for 2 different connectors, and thats alot at todays gb/$ prices for hard disk storage. And probably it still sucks, you can't tell for true if you read the reviews about NAS solutions, ..

Finally intels dualcore atoms have arrived and seem to deliver enough bang for your bucks to hold up as storage and media streamer, passive cooled, so silent and only taking like 15W plus an extra 3-5W for each hdd.
The hard thing is finding a fitting power supply with ATX connector that delivers under 80W. The best seems to be some DC-DC converter like these picoPSU. Used with a simple 12V notebook power supply, and everything is fine! And none noisy fan anywhere!

So, thats what its like:

[Update] (FreeBSD Compability)
FreeBSD works well on D510Mo. Just hardware video (Intel GMA 3150) is currently not supported, so no 2D/3D acceleration. VESA starts up X, but don't use that either, so doesn't matter, ..

For those that care, dmesg at end!

So performance wise, this little thing rocks! I've been rsyncing files for half a day now, doing a total of 250GB now and the cpu is at 30°C. The cooler is barely handwarm, and my 1,5TB WD green carrier could do 90mb/s sequential, benchmark say. Don't get that much from client,.. truecrypt over 2,5" usb hdd delivers around 10mb/s

And as a last note, ZFS ist simply stunning. Never set up encryption and filesystem structure that fast!
[/Update]
[Update 2] (Power Consumption)
PicuPSU has finally arrived. Its stunning, no noises ad so tiny! Even the 80W version is working properly. At first, I was a bit scared about power peaks at the disks spin up. The manual says 7A at peak load for less then 60 seconds should work. I guess, thats more then enough for 2 disks, since i even turned on 'delayed boot up' in the BIOS.

Unfortunately, I've only got a digital multimeter with TrueRMS. i wouldn't count on the correctness of the given values, since they are really not made for measuring switching power supplies, but well,..

It is:
- 1,5W in standby, and
- 26,3W at full boot up, and idle.
- I've seen it above 41W when the disks click in.
Note: Just for the records, it had around 38W at idle with my cheap, 25EUR ATX, Rasurbo 450W PSU

Thats not the best, probably a cheap 12V power supply.
I'll do a measurement after the 12V supply, and before the Pico, that should deliver some good data.


EDIT: Others say, it idles at 15W, with one hard disc, and the rest of the configuration is the same.
Not sure, if thats any better, since it looks like a cheap, 20USD building center analyzer, and they also not made for low currents, since they've usual a accuracy from +/- 10W..

My guess is, it's more around the 26W, since intel is giving a TDP of 13W for this board, 3-5W per disk, and say another 3-4W per SO-DIMM, whats a total of 25W. Now, calculate the efficiency of the power supply on top, and i think 15W is a dream value!

My main goal was the audibility anyway, ..
[/Update 2]

If you have no old hardware lying around booting Freebsd over PXE is explained here!

Prices for hardware in a comment at end!

Moin.

Dann würde ich aber noch ne PCI (W)Lan Karte stecken und das ganze zu nem Router mit integriertem Kram (Mailserver/Firewall/FTP/VPN usw.) weiterbauen. Evtl auch n Squid dabei.

Hab sowas ähnliches mal aus einem Thin Client mit ner kleinen SSD gebastelt.

Ich hab noch n OpenWRT, der als AP für mein Zimmer dient. Da ist an dem 1gb switch das D510MO angeschlossen, mein notebook, und ps3.
Der OpenWRT leitet dann per WLan an den Router weiter. Ist die best mögliche Konfiguration, ..

Hab auch erst an PCI Wlan karte gedacht, aber ich hab NFS über wlan probiert, das ist kein Spaß. Kaum Durchsatz, und das ist auf keinen Fall dafür ausgelegt, das die Verbindung einfach mal "weg" ist ..
Ich steh eh eher auf Kabel, und n Daten Server per wlan ist einfach fail!

Danke für die Idee trotzdem ;). SSD wollte ich auch mal probieren, .. fehlt nur gerade an kohle, und mein notebook kommt mir noch nicht zu langsam vor ;)

hiya!

I'm not exactly sure, if it's the answer you're looking for, but HW ist quite obvious, and common, so cheap:

  • The atom board: I've used the D510MO from intel itself. The passive cooler is included, and sata cables for hdds. (Around 80EUR)
  • Power: Thats the biggest problem: I started with a cheap 25EUR ATX switching power supply. Thats because it was the one with the lowest Maximum Power value. I'd recommend one of those picos (DC-DC, so very good efficieny and almost no power loss) as meant in the article for a suitable efficiency (~80EUR). You should run your supply at around 80-100% of its maximum power, if you don't want to lose more power than you actual safe. (25EUR)
  • You need some RAM, I've got one 2GB 800-DDR2 dimm (~50EUR)
  • HDD: I've got 2 WD green caviar ones (~75EUR each)

Should be quite similar in USD. Thats around 250EUR.

A quick note: The performance (90mb/s) as shown above is for unencrypted devices. I'm uncertain how to test the raw performance of my GELI-AES256+zfs encryption speed, without my network bottleneck, or read and writing from the same disk (de/encrypt), ..

You can also use the ahci(4) driver with this motherboard's SATA controller:


ahci0: port 0x30b8-0x30bf,0x30cc-0x30cf,0x30b0-0x30b7,0x30c8-0x30cb,0x30a0-0x30af mem 0xf0380000-0xf03803ff irq 19 at device 31.2 on pci0
ahci0: [ITHREAD]
ahci0: AHCI v1.10 with 4 3Gbps ports, Port Multiplier not supported
ahcich0: at channel 0 on ahci0
ahcich0: [ITHREAD]
ahcich1: at channel 1 on ahci0
ahcich1: [ITHREAD]
ada0 at ahcich0 bus 0 scbus0 target 0 lun 0

Japp. Thanks for your comment. I retried it on your suggestion, and it finally worked..

I've read about the new driver as well when buying the board, but never got it working. NCQ and setting the damn APM/AAM to off is a nice feature to have.
Either the device names didn't fit during boot and it panic'ed, or, i guess, i've just overlooked the settings in the BIOS. What a shame, that they turn it off by default?!
So, for all the people trying to get ahci(4) working on this board, turn it on in the BIOS, and if you didn't load the module at your install (kldload ahci.ko), either label your devices or correct your fstab. Not by just putting an 'a' in it, like me, but completely rename then. My ad4 became ada0, ad6 ada1.

Hi,

I want to install two 6 TB HDDs in the D510MO. Will this be able to? Or is the HDD too big? Does anybody tried something like this?

Thanks for informations.

Hi,

You should not encounter any problems. I'm running two 3.0TB WD RED disks at my M510MO at the moment, and there isn't any limitation regarding size after the 2TiB 32-bit sector addressing.
