Pretty interesting article from ArsTechnia on the new version of Hyper-V announced yesterday. I wonder if the hardware requirements are any less picky than ESXi? Would this work for unRAID do you think? Can't see why not...
I for one am going to be attempting an install over the next few hours to see what's what. Dependent on my crumby internet downloading the ISO (ETA 14 hours!).
Oh, and did we mention that whole "free" thing? Unlike the free license version of VMware's ESXi, the free version of the Hyper-V hypervisor is just as capable as the version that ships as part of Windows Server 2012—there's no cap on the supported memory or number of processors. Hyper-V Server 2012 is a full-feature version of the hypervisor, with all of the same manageability features of the Server 2012 component. If you're not planning on running a Server 2012 license in a hypervisor, but want to run other operating systems as virtual machines (such as Windows 7 or 8 for a virtual desktop infrastructure, older versions of Windows Server, or Linux) using Microsoft management tools, Hyper-V Server 2012 is all you need. -
cables would be practically in the middle of the case. i didn't put them in sketch up, but they would not be by the fans. another issue with rotating the drives is they'd then be too wide for 350mm.
does anyone know of a good way to produce some smoke (or something like incense burning) to get a visualisation of airflow?
-
in terms of cooling, what's the best orientation for the air to flow over the drives? cabling won't be toooo bad. i have lots of heatshrink and braiding to aid there.
why would rotating the drives make cabling any easier??

Hello everyone! I'm just embarking on a very exciting project which I'm going to call 'The Tesseract'. I'm going to build a server cube from wood in my spare time over the next few weeks. The plan is to house as many drives as possible (but at least 10, my initial plans suggest 16 will fit) in a near silent enclosure, with drive temps in the critical 30-40C range.
I've done some very rough mocking up in sketchup to help visualise my concept and settle on a good size for the build. The sketchup models are missing crucial details about how to drives are going to be mounted as I couldn't figure out how to draw string! Each drive is going to be suspended on elastic bungee cord to minimise noise transference. Each fan has to be rated at 25dB or less, going for larger whereever possible and will be mounted against the wood with foam for cushioning. I'm going to go to as much effort as possible to minimise noise.
My current setup is a Fractal Define XL. In short, I don't like it. Too big, too heavy (my back hates it too!) and my drive temps regularly hit 40C even with aftermarket Noctua's in there. It's not that quiet either with a lot of vibration transference even though the drives are already in the trays with rubber grommets. Dissapointed doesn't even cover it - this case was supposed to be my Nirvana! Anyway, after hours of searching online I'm giving up trying to find a premade case for my needs and am going to make my own. I stumbled across a fantastic build on youtube for a wooden cube case with a patchwork exterior and knew my search was over. It's just beautiful.

With this in mind I set about making it smaller, and more to my tastes. I have no need for an optical drive or usb ports to be accessible, even the power switch will be around the back out of sight. Here are my pathetic sketchup attempts... The case is going to be around 350mm square. I'm toying with the idea of making the case a little larger to accomodate cabling requirements but would REALLY prefer to keep it at it's minimalistic 350mm cube size.
The hard drives are in two stacks of 8 drives each, cooled by 4 140mm 700rpm fans. I have 4 differents makes on order including Scythe and Thermaltake to test and then will choose the quietest. The drives will lift out almost like a honeycomb from a beehive, in a slotted wooden frame I'll knock up. Doesn't have to be pretty anywhere except on the outside!! The mobo will have stock CPU cooler so not much clearance required.
Hardware
I already own and use all existing hardware. Eventually will upgrade this to a Supermicro Xeon setup for ESXi, that's next on the WAF list. This thread is, for me, about the build of the case. Hope you enjoy it's slow (and most likely) painful birth!

Awesome, disabled the sickberd plugin and she booted just fine. Will look into how to get it to wait on boot.
My mover script ran again overnight and broke Sabnzbd again by moving the cache only share across as well.
How do I fix this ?
-
Hi,
Problem started with mover - it was ignoring my cache only share with sabnzbd on it and moved it across to the array causing SABnzbd to break. I SSHd in and forced a reboot. Parity was correct at this time having just completed a parity check a few minutes before.
Upon reboot emhttp will not load no matter what I do. unMENU is fine, sabnzbd is fine (albeit not configured for anything as the .ini is somewhere else now) but the main unraid web ui just will not load. this is from multiple computers, iPhones, windows and mac and an ipad. so it's NOT that anti-virus issue as i don't have anyway!
further to this the array is not mounting and user shares are not accessible. HELP!
EDIT: Unraid RC5-8168, i3 2120, 8gb ram. Memtest was run 2 weeks ago for 48 hours, no errors. All drives were pre-cleared before putting into the system. I would assume it's not a hardware error at this stage though...
EDIT2: I've just run ps -ef | grep emhttp | grep -v grep to see if that helps anyone else
ps -ef | grep emhttp | grep -v grep root 8138 1 0 22:15 ? 00:00:00 /usr/local/sbin/emhttp root 8344 8138 0 22:15 ? 00:00:00 /bin/bash /usr/local/sbin/emhttp_event disks_mounted root 8450 8344 0 22:16 ? 00:00:00 /bin/bash /usr/local/emhttp/plugins/sickbeard/event/disks_mounted disks_mounted

FYI - parity sync finished this morning.
so far am 824GB into my 2.5TB transfer and have seen steady 30-50MB/s write speeds. don't want to count my chickens yet but it looks like waiting for the parity sync was the answer.
-
just an update - have transferred several more files since earlier, one MKV file was 32GB in size.
all was going fine until it hit the 22GB mark, transferred at 30MB/s, then suddenly like it hit a wall BAM - down to a 2-300KB/s.
Parity sync is still ongoing but I'm curious as to whether this is normal or not...
-
i just rebooted. ah yes, i also rebooted via ssh...
i get the same results whether a parity check is in progress or not btw.

Hi,
Newbie here so go easy please! Wanting to fill up my new server with around 6TB of data - once this 6TB is added I'll be adding a 1TB cache drive. All is great until we're around 20GB into the transfer then things start slowing down.
My transfer speeds to a brand new array are erratic. My peak is 55-60MB/s, but the lowest can be as low as 2-300KB/s. I transferred 22GB worth of MKV files (so lots of large ones is what I mean) at the peak rate, but then the transfer speed dropped down to the lowest. It's currently hovering between 600k and 2MB/s. See screenshot for what I mean...
My hardware is as follows:
unRAID Server Pro v5 rc5-8168
Asus P8H77-V LE, BIOS 0237
Intel i3 2120 3.3ghz
8GB RAM
TX750W Corsair PSU
1x Supermicro SAS-AOC-SASLP-MV8
2x 3tb drives, 1x 1.5tb and 1x 1tb drives. All precleared successfully (reports attached for what it's worth).
What have I done before posting?
- I pre-cleared all drives on 2 passes.
- I've switched from Unraid rc5 to rc5-8168 without any noticable difference (currently running rc5-8168).
- Used two different gigabit switches (identical results)
- Swapped all cables several times (identical results)
- searched the forums
- fiddled around with MTU jumbo frames (identical results, back at default now)

I've not yet completed the initial parity sync (through sheer impatience!). Would this resolve the issue most likely? Transfers being done over gigabit ethernet from a Windows 7 machine. Read transfer speeds are in excess of 80MBs so I don't suspect network hardware at fault here...
Any help please? My gut feeling is that it's related to that initial parity sync? Please tell me I'm right!!
