Why am i worried about airflow

Hey faggots I am building a file server and I am going to put it under my spare desk in my room.
This desk is built into the wall in a weird way and there is a hole in the lower rear wall (where your feet would go). This hole leads to a crawlspace that is behind the desk.
For the last few years I've just had the crawlspace filled with shit and have piled a ton of shit out in front of it to stop my cool air/ heat from escaping. I have cleaned it out so i can put the server there and I VERY much want to plug the hole up so it will keep my room cooler and stop bugs from coming in. But I am worried about the heat from the server.

So my choices are :
Keep the hole open, let all my cool air flow out but the server will be able to dump its exhaust into it too

OR

Plug the hole up but the servers rear exhaust is going to have nowhere to go besides up and to the sides

I don't think the server will get hot that much anyway I am just using a dual core phenom II with the stock cooler and 4 hard drives
but I am paranoid...
how would you do it Holla Forums??


ALSO :
what kind of software are you guys using on your home servers I need to be able to share certain folders with all computers but share certain folders with only certain computers (PORN)
Not sure of OS yet probably funtoo or freeBSD.
I'm going to use ZFS with RAIDZ1 (raid 5) I REALLY doubt 2 of my drives will ever fail at once unless something catastrophic physically happens to the server.
I will update later with images of server when I get the parts in.

Use.
the motherFUCKING.
Sticky.

u did not read the thread do you really think I would come back to the sticky later and provide progress updates to server ?
stop being a faggot

reddit faggots like this are why there is NO OC on tech

Is this space ventilated? You have holes in your walls that expose the inside of the house to the outdoors? You don't have rats coming in through the hole?

It is on the 2nd floor and is a pretty closed off crawlspace I think it was originally for storage but who knows, there is also a live AC line just hanging around in it and exposed insulation.
I did not find anything dead while cleaning it out but i sure as fuck have smelled something dead coming from under there before

You do realize that the sticky is for hardware troubles, right??
You do realize that you can quote the person who offered help to you using two greater-than symbols, right?
Mongoloids like you are the cancer of pigchan.

hotglue and scotch tape really doing some work here

Holla Forums Holla Forums is for the sole purpose of meta-drama, backseat moderating, and a "circular" "sticky" thread.

Actual technology threads belong on 16chan now. Leave the sagelord to wallow in his own kiddie porn spam.

Fuck off and let people discuss technology. There is more to the topic than linux distros and text editors.

If it's closed off then it might not make a good vent. Just sayin'.

That's what I'd do.

WHAT KIND OF FUCKING GAY SHIT IS THIS
REEEEEEEEEEEEEEEEEEEE

shipping from China?

enjoy your pigshit.

I have received 2 of my hard drives, here are the results of the first drive, I cam assume the 2nd will be identical since they are both the same drive and manufactured in the same month seems good so far.

VERY buttmad about the sata cables though, since when does amazon sell shit from china and not tell me?

Go home Josh.

oh we will. enjoy being homeless.

Don't think of it as slow, think of it as a surprise with will probably happen in the next 3 months!

it literally tells you in the checkout process right before you hit order how long it'll take to get your stuff

idk my main data drive (G:) is still kicking and it has similar speeds pic related with 43826 hours as well as my E: drive with 48529 hours, both are hitachi 2tb and 160 gb respectively

so this is the 2nd drive and I am not sure if CDM is just fucking with me or what
I switch the tests around and i will occasionally get stupid fast speeds like this or 160 like the other drive.
this disk also seems to run SLIGHTLY warmer

I have my home server in a cabinet under the stairs for a couple of years now. You don't really need to worry to much about airflow. I do have central column in the house that goes up to the roof, sort of just a 300mm x 500mm empty space behind to wall that I've attached some 240mm slow fans to behind a filter.

I'd go for RAIDZ2 or RAIDZ3, usually if one disk fails chances are another disk will fail on rebuild. I use freebsd on my NAS server, as at the time I set up the system ZFS on Linux was still immature, probably fine now seeing as there's a lot more support.
I just used an old IBM X3500 5U rack mount server which I replaced the internal parts with a newer dual amd opteron 4276 HE system and a Dell H310 Perc with IT firmware (was using on board sas2008 controller, but that's for backup array now)
Its an 8 disk 3TB RAIDZ3 array by the way.

All up don't fret too much about airflow, I get 45C temps here (aussie) and have never seen ambient temps go up above 60C on a really hot day. Right now its sitting at like 30C and its in a way cramped spot. Focus on getting a case with proper airflow and decent fans. The IBM system I used has these nifty hot-swappable 120mm fans

...

I see people saying this everywhere but i see no real proof for it, it simply makes no sense. Barring a physical event to the computer there is NO reason ever why 2 drives would ever fail at the same time (unless you are just REALLY REALLY unlucky)
The only other reason I might see this occurring is from a bad batch of drives that all have some defect.
There is simply no reason why 1 drive failing would ever in a million years make another drive fail unless there is some kind of underlying problem with the rest of the computer.

I just realized now you were talking about the sata cables arriving and not the drive speeds


speaking of drive speeds I switched CDM to random data and single thread and am now getting pretty much the exact same results as the first drive so thats good! I was pretty sure i tested the first drive with the same settings but idk

I am only using 3 storage drives at the moment so raidZ1 is the only thing I can do. Is it possible to change zfs raid levels on the fly without data loss? I will obviously be getting more drives and will use Z2 and Z3 once I have enough.
I was going to get an HP proliant but the guy sold it before i had a chance T_T

It does happen, usually such a case occurs when you buy drives together, you might just get a shit batch and a rebuild might put extra strain on a dying drive to kill it.
I personally haven't experienced it but a friend of mine was working for business a few years ago when a company server (RAID5) array had a second disk fail on rebuild.
Really the safest thing is to have multiple sources of backups, you can't just rely on a redundant filesystem alone. If anything you really only use redundancy just for added performance benefits.


Wouldn't recommend less than 4 disks for RAIDZ1, may as well use RAID0 at that point (probably faster too if its unimportant stuff).
You have to backup and destroy arrays if you want to upgrade down the track.

Try fleabay or go dumpster diving for cheap shit.
