Hey /g/, what would you say is a good solution for a low power home server?
Uses:
>host my email IMAP and Roundcube
>Owncloud just for my personal files, calendar and contacts
>OpenVPN
>about 1000 What.cd Torrents
You think a single board computer like the Raspberry Pi is enough or will I regret it?
I have no idea, but I want to try the same thing. Hopefully more fag/g/ots will get in here.
>>51831938
looking at it specs
its is definetly slow as fuck
>>51832066
Any other low power suggestion?
>>51832000
Checked.
Nice trips.
>>51831938
How about an atom board? I'm sure that'll be quite a bit faster and still barely use much power? I almost bought one for 60 ausidollas. The asrock j1900.
Pic related, shit american prices. But still, it takes sata drives which makes it worth it in my opinion. On the other hand the rpi comes with ram preinstalled and runs off a micro USB connection.
I'd still take the atom though because ram is cheap and 1gb doesn't seem very appealing.
And if money's an issue there's always the orange pi pc.
>>51831938
You won't get any decent vpn speed of it, low atom would be better desu
>>51831938
the Raspberry Pi network is just soldered on the USB bus so it's very slow.
Don't try to find a single device that can do all of this
Buy a NAS like a Synology DiskStation with Western Digital Red harddrives
Then for IMAP/Roundcube just use a generic cloud provider
>>51832178
Get this, fãm.
>>51832178
That's some pretty good info for me right there kind anon. Thanks.
SATA is valuable. Ain't the j1900 a Celeron though?
>>51832261
I'm sure it can net me about 3mbps which is my upload speed anyway.
>Buy a NAS like a Synology DiskStation with Western Digital Red harddrives
Overkill. I only need one of my already existent 500GB discs or less.
>Then for IMAP/Roundcube just use a generic cloud provider
I already have my whole system setup on a home-server. I'm not looking into changing anything. Just the hardware to something low-power. My current server wastes 33W on idle 24/7.
I meant to quote >>51832328 in >>51832365
>>51832365
>isn't the j1900 a celeron
Oops, yeah you're right.
I still think it's great for low powered applications though. 10w tdp. And upgradeable ram.
The pi is stuck with 1gb. The j1900 takes up to 8gb which is plenty.
>>51832363
>>51832420
Those are very tempting anons.
>>51832000
>>51832178
Go back to /b/, we don't like your kind around here.
>>51832638
I don't like your attitude, sonny. You wanna come play on my Amiga?
Just build an AM1 desktop family. The requirements you have might not be satisfied by a 512MB RAM raspberry pi.
You can build a really cheap AM1 build for almost $100 too (assuming you use the $25 Sempron 2650).
>>51832655
For am1 the only one worth getting is the athlon 5350.
Also 25w athlon vs 10w celeron?
The athlon is a little faster iirc but if energy consumption is a concern the celeron is better.
>>51832655
>>51832748
I'm using a 33W machine and I'm trying to reduce it down. Is the Atom 10w rating for the CPU or the whole system? (mobo + cpu)
>>51832655
$125 build which includes [2] 1.4GHz cores, 2GB RAM, and 160GB HDD
http://pcpartpicker.com/p/6zsrK8
>>51832650
Wait wait wait, how are you posting on here if you're using a fucking amiga? That's some voodoo black magic crap I tell you.
>>51832783
33W is already pretty decent. The j1900 is rated at 10w and I believe there is a single core Atom NUC rated a 5w. Are you using a kill-a-watt or something similar to measure at the wall wattage?
>>51832879
>kill-a-watt
Dunno what that is but I use a wattometer at the wall socket yes. It measures 33W at idle.
I'm considering using my EEE as a server as I think it only consumes 13W or something, not sure.
>>51832748
Yeah the celeron has better performance and lower energy consumption. Seriously though the differance is extremely tiny especially since the CPUs will never be under heavy load 24/7.
I'd still recommend the Sempron 2650 because you can sometimes find it for $20 +$25 motherboard. It's cheaper than the celeron motherboard AND you can upgrade to an Athlon 5350 later.
>>51832850
I can be posting from a different computer, you know.
>>51832973
Come on man, its a joke, just play along!
>>51832783
Cpu only.
33w is very nice for the whole system though. Are you using a hdd or ssd?
What os? Does it have an energy saving mode like windows?
>>51833027
2.5" HDD
It's running Debian.
>>51832363
Wow, shit.
Had no idea they sold motherboards that cheap.
>>51833027
>33w is very nice for the whole system though.
Even if on idle?
>>51832916
You do get the added bonus of having some motherboards with 4 SATA ports going AM1. I'm not sure if there are any 4 port j1900 boards. You could add a PCIE controller and get 4x SATA per 1x SAS port from that though.
>>51831938
I've never seeded that many torrents at once, but I am nearly convinced that you want some sort of proper machine for that kind of load. RasPi 1 at least is very slow, it almost certainly won't handle it.
I'd suggest going for one of those x86 ITX boards that come with a soldered CPU, generally some sort of Atom, at least.
If your data matters to you, you may also want to look into some sort of solution that provides a bare minimum of redundancy in cases of HDD failure, something like ZFS or mdadm software RAID.
>>51833027
Not that guy, but about power consumption. I have a home server made out of desktop parts, i5 4570S CPU, 12GB leftover RAM (4 sticks) and 6 3TB WD Reds. It pulls 42-46W at idle and by idle I mean all services up and running but no significant load.
OS is headless Debian 8.2. I'm very happy with its power consumption, this is less power than a shitty incandescent light bulb for 18TB of network storage and quite a decent bit of CPU performance available when required (i.e. high quality Plex transcoding).
>>51832916
>upgrade to a 5350
That sounds like a bad idea.
If op needs the performance the athlon is the better option, but you've also got to consider the tdp is 2.5 times higher and you don't see a significant improvement either.
Don't get me wrong, the athlon is a great processor for the price, but at the same time it's just not as efficient as the celeron.

>>51833310
I'm OP. Sorry I didn't specify but I was talking about the Raspi 2.
I already have backups set in place so don't worry. My current 33W at idle server is an old Core 2 Duo laptop that is now headless.
If you can have a 45W idle machine with a proper CPU, 12GB of RAM and 6 HDDs, I believe I my system, with a single 2.5" HDD could waste much less watts. My main priority here is reducing the wattage. The Core 2 Duo would otherwise offer more than enough performance.
you should probably kill yourself so it will all work out on 0 W
>>51833328
I never understood why efficiency matters below 50 watts. I mean even home servers don't run 24/7 on max load. Even if you encoded video for 8 hours a day for 30 days, you'd end up paying 2$ of electrical use (12kW@16¢/kwh). In reality most people would bever use 12kw of electricity in a month for a 50 watt server.
Are you people paying a $1 for every kw of electricity used or something?
>>51833524
And make that $1 for a encoding video 8 hours a day for 30 days if the system uses 25 watts under heavy load continuously.
>>51833401
>If you can have a 45W idle machine with a proper CPU
You definitely can, mine is all desktop shit. The motherboard is a Z87 model, I got it because it had VT-d support.
>>51833401
>reduce wattage
Why? Are you paying a $1 for electricity or living off solar panels?
>>51833524
>>51833687
>I mean even home servers don't run 24/7 on max load.
My home server is wasting 33W on idle, not on load. I would be ok with that on load.
Dunno how much electricity costs in the US but from my calculations here 33W 24/7 for 30 days is about 4€. Not much I know, but if I can get a more efficient and powerful CPU, I will. A Core 2 Duo T5500 is not the most efficient thing out there nowadays.
>>51833731
That still isn't very much. It would probably take years and years for you to get the money back you pay for a new platform simply through money saved on power.
>>51833731
>My home server is wasting 33W on idle, not on load. I would be ok with that on load.
That doesn't make any sense, the C2D T5500 has a max tdp of 34 watts. Are you encoding on your server 24/7?
>>51833831
TDP is related thermal design, not what it pulls at any given moment.
>>51833831
A server isn't a CPU plugged straight into the wall anon. Everything else also needs power in order to function and there's also PSU efficiency to consider.
PSU efficiency usually isn't at its best at very low load and 30W is very low load for pretty much any desktop PSU, so depending on how good or shit it is, it may not be very efficient at all.
>>51833831
>the CPU is the only component that consumes power
>>51833731
That 4 euro a month builds up after a while too.
48 euro a year.
And that's idle wattage, not under load.
>>51833843
Higher tdp assumes higher wattage.
Why are people here against efficiency? It's not pointless, electricity may be cheap but it's not free and costs build up.
>>51833843
It's really close to what the CPU uses under load (assuming base frequency and no turbo)
>>51833863
Still, a server idling using 33 watts with a 34 watt tdp CPU on idle sounds insane. Maybe the PSU is shit like you said but I thought even chink PSUs could achieve at least 70% efficiency?
>>51833920
Not same anon but the components aside from the CPU and monitor don't consume that much power.
>>51833134
I run an fx 8350 off a motherboard that costed $59 3 years ago
>>51833925
even if you cut it in half you'll save 24 euro per year so nothing. if you really want to save stop the autism, use gmail and gdrive, shutdown the useless what.cd seeding and get rid of your home server.
>>51833991
Go away google shill.
>>51833970
It's certainly reasonable that they consume a couple tens of watts
>>51833938
It's not that much power, especially with some other hardware like a few HDDs. I had an old Atom server (D2700 IIRC) that was running off of a SD card with an external HDD, the server alone idled at ~10W with a 10W TDP CPU. The PSU was some noname small form factor thing that came with the case, I imagine it wasn't the most efficient thing around.
I don't quite remember, but I think I also measured my RasPi and it was pulling like 3-4W.
>>51831938
Just get a cheapo Intel Atom dual core all-in-one off ebay for about $45, get a cheap little case for it, pico PSU, and a single DIMM of DDR2
Many times better than the RPi.
>>51833991
>24 euro a year is nothing
You're forgetting that's when idle, not under load. And some of us would rather spend 10 euro more on the purchase to save 24 euro PER YEAR.
Every saving matters, I'm not a fucking millionaire.
>>51833731
I bought an ASRock QC5000 for my home server. It has an A4-5000 quad core in it that's got a 15W max TDP. Very power efficient. The case I have it in is the size of a shoebox. It's an embedded CPU design, though, so there is no upgrade path, really. Intel has offerings as well, so you might find something that suits your needs better-- I just wanted a quadcore for Plex transcoding.
>>51831938
RPi2 is absolute garbage for a home server. The ethernet shares the same bus as the USB so transfer speeds suck.
Look at the ODROID XU4 if you want a home server. It actually has Gbit ethernet and USB 3.0 and a MUCH faster CPU. It'll ass-rape the RPi's performance in every way. It's like four times faster for only about twice the price.
>>51833988
>costed
It's just "cost", anon.
>>51834140
>spend 10 euro more
a new server is going to cost you way more than 10 euro, if you're really that poor as I said earlier just get rid of the home server.
