I run a debian derivative called raspbian and i'm looking into a new
build cluster both to give more power for the jessie campaign and to
migrate the cluster out of mike's basement. I had been looking egarly at
the openbrix zero but it looks like that project has been abandoned :(.
I've thought through a list of requirements and nice to have's and am
currently looking at two boards the nitrogen6x (with 2GB ram option) and
the arndaleboard.
Required:
Reasonablly priced. I am hoping I will be able to get our build hardware
sponsored but I still don't want to take the piss by specing hardware
with poor bang per buck.
Reasonable cost of entry, I'm not going to spec out a cluster without
having a single board for testing first.
2GB ram minimum, more would be great
SATA, I don't trust USB and it also makes the physical mounting awkward
since the USB-SATA adaptor has to go somwhere.
Ability to get a debian or ubuntu based system (ideally debian) running
on it easilly
Preferable:
Physically small (if I could shove four of them in a standard 1U
rackmount server case that would be great, the nitrogen6x wins over the
arndale here)
Support in a stock debian kernel (is either the arndale or the imx6
supported in debian kernels or likely to be supported in the near future)
As much total CPU power as possible (I think the arndale marginally
beats the nitrogen6x here if wikipedias claim of A16 being 40% better
than A9 is realistic, anyone have any numbers here)
Fast dual core processor preffered over slower quad core (arndale beats
nitrogen6x here).
Are there any other pros/cons I should be aware of in a nitrogen6x vs
arndaleboard comparison? Are there any other hardware options I should
be considering?

when Wheezy moves to Stable?
This would be good, but might cause a little breakage as the new
versions flood in from Sid after the switch over.
I really admire the work you've done on Raspbian. Thank you!

to create raspbian jessie to follow debian jessie but there is likely to
be a delay between the creation of debian jessie and the creation of
raspbian jessie. Also the ammount of breakage in raspbian jessie is very
likely to be higher than in debian jessie, especially during periods of
heavy development.
The tentative idea is to set up the new build cluster for raspbian
jessie while the existing build cluster continues to build raspbian
wheezy. Then when all the gremlins in the new cluster are sorted out to
move raspbian wheezy over to it as well.

Apparently the USB3 socket is not actually useful. anandtech.com
Benchmarked it when they reviewed the Chromebook, and only got
12.7MB/s (while running ChromeOS), which is barely more than the
maximum speed for USB2.
Having said that, the Chromebook might still be workable, if Peter can get the working files for a build into the 16Gb of on board flash, and then boot the build environment from a slower SD card or USB key.

i know that method of measuring isnt very scientific but this is what i
get on a userspace level (not turning off caches or using raw
operations, but after all thats what you as user will see as well) ... i
wonder if they tested the right port :)

(Re-posting to the list, I replied only to Peter before.)
Have you come across the cubieboard <http://cubieboard.org/>. It only has 1Gb of RAM, and a single core Cortex A8 CPU@1GHz, but it is a quarter of the price of the nitrogen6x (Which also only has 1Gb of RAM unless you pay an extra $50) so it might be more cost effective to more of them, and buy only one or two larger boards to build the most memory hungry packages. It is the size of a Raspberry Pi.
The other option would be to approach one of the System integrators who a working on dense rack mountable ARM servers for the data centre and ask them if they would sponsor you by providing some hardware. You project must get a great deal of traffic, and a "Your add here" at the top of your home page would go a long way. The company I work for is a medium sized Dell costumer, (To the tune of about $10k of servers per month) and I know that several of us are also Raspberry Pi enthusiasts.
You might also try approaching ARM directly, as they might have some better development hardware they could lend you. I have a friend who works for them on gcc support. I could approach him if you think it might be helpful.

While the board itself is a fifth of the price of an arndale or 2GB
nitrogen6x you run into the issue that when boards get that cheap the
accessories (hard drive, bay to put the hard drive in, network port,
serial console connection etc) start costing more than the board itself.
So i'd imagine the total cost per board is more like a third to a half
the total cost per board of a 2GB nitrogen6x or arndale.
Also the impression I've got from various discussions over the years
(mostly involving mips iirc) is that debian lacks both the metadata on
package build requirements and the tools to use that metadata to
efficiently run a hetrogenous build cluster.
the lines of "we and calexeda are too small to give out
freebies/discounts to open source developers". When I approached
baserock about the slab I didn't even get a response to my email.
I haven't approached dell or HP because frankly i've no idea how to do
so. I don't think contacting the general sales address at a megacorp
like that would be very effective.

I don't see any real reason to choose the chromebook over the
arndaleboard though (same processor, same ram, about the same price,
worse interfaces).

1. How much of them will you need ?
2. It may be difficult to put the arndale board into a case which can
be mounted into a rack. It looks like the arndale board has its
connectors at least on 3 sides of the pcb which doesnt't make it easier.
3. Which interface would you like to use for mass storage ?

As another data point...
I'm looking at migrating the current Debian buildd machines across
from imx53 to arndale in the next few months, using a similar kind of
setup to what we have there right now [1]. The arndale boards are
physically too large to fit in the existing mini-rack so I'm expecting
to swap from there to a new 6U version. Thankfully, the arndales look
like they should work fine using the same power/SATA/ethernet options
as we currently have which will make things easier.
There are 2 potential worries yet. AFAIK, the kernel for the arndale
is not yet upstreamed enough for our purposes so we'd have to run a
locally-built kernel for a while; I'm hoping this will get fixed in
time. The second issue is reliability - various people have reported
instability when working their arndale machines hard for
building. Again, I'm hoping this will get fixed in time.
What I'm planning on doing in the short term is replacing an
already-broken imx53 in the Debian build cluster (hartmann) with an
arndale and seeing how well that holds up under load. If all looks
well, I'll get more and start swapping out more of the machines and
probably some of the older Marvell armel buildds too,

seriously. i've posted on this previously (4 months ago, 5 months ago
and 8 months ago approximately), as well as there being an independent
post by someone who noted that modifications to one package required,
if memory serves correctly (which it usually doesn't) *six gigabytes*
of swap space in order to effect a link.
to repeat again: the example that i give is the one that i know well
- webkit, which requires at least 1.4gb *resident* RAM in order to
complete the link phase in a reasonable time frame. 15 minutes is not
unreasonable on a 2ghz dual-core XEON... *as long as* you do not
require debug information. if you require debug information (dbg deb
packages) then you're looking at around an hour.
if however you only have 1gb of RAM then that 15 minutes turns into
90 minutes, and christ knows what the debug build link time is, i
never bothered to find out because i have better things to do. and
that's with dual-core XEONs.
the debian ARM build systems which previously had only 1gb of RAM i
believe they were looking at 2 days for the link phase on some of
these larger packages.
so, yeah - word of advice from experience: *DO NOT* get a system with
1gb of RAM for building of distro packages, if you want to have a life
:)

boards. Now an arndaleboard should be more than twice as fast as an
imx53 even in non-parelellisable builds but debian is growing over
time. I'd guestimate six arndales would be enough to do us for a while.

HDMI which we would not be using so there is no need to leave space to
plug it in. The arndaleboard is 140x195mm.
You can easilly find 1U cases that are designed to take an EATX board.
EATX is 305mmx330mm. If the long edge of the arndaleboard is placed
along the short edge of the space with the connectors facing inwards
that gives us 50mm of connector space between the two boards for
connectors on the long edge and 110mm of space for the eSATA connector
on the short side.
So I think two arndaleboards in a 1U EATX case would be tight but
doable. The biggest problem would likely be the serial console connector
and it may be nessacery to use a custom cable for that either using an
IDC D connector or using a conventional solder or crimp connector with
no backshell.

My understanding is that there is no heatsink on the CPU. If that's the
cause of the problems, it could be easily fixed by attaching one.
I have ordered an Arndale board which I intend to fit in a small 1U case.
Ordering was a total pain: it honestly said "this website best viewed with
Internet Explorer 10", and although I ordered it on 15th Feb it still hasn't
been dispatched. It's also a bit worrying to see that the "OPENBRIX /
ARMBRIX" board, which is essentially a stripped-down Arndale, has been
cancelled "Due to a situation experienced by the ARMBRIX Company"
(news item at http://howchip.com/ ).
Cheers, Phil.

Hmm, worked just fine with firefox (iceweasel) for me. With a bit of
luck there is full kernel support when it arrives :-)
Btw, I've searched quite a bit to find a suitable way to connect a ssd,
and think I might go for the "Silverstone SD01":

them to be utterly, utterly shit. to the extent that, it is
well-known and *already* in the linux kernel source tree, for at least
18 months possibly more, that the support for e.g. GL830 usb-to-sata
IC actually has an algorithm "if chip crashes then reset it without
notifying the user, repeat until success". trimslice used the GL830
in one of their boxes (the one with the nvidia tegra), and it wasn't a
good idea.
on the other hand, some people have reported that if you pick the
right usb-to-sata flash drive, you can get exceptional reliability.
gordon on arm-netbooks did a write-up about 18 months ago - he's
extremely knowledgeable.

I know you have said that some USB mass storage controllers are
unreliable but is it really that bad for all of them? Is there a list of
known good controllers or ones to avoid?
I have been investigating ARM dev boards for an unrelated project of my
own, and discovered that thought there are plenty to choose from, a SATA
port appears to be a rare feature that increases the price considerably,
which got me thinking that the raw speed of USB2 should be adequate so
long as it is reliable and does not add too much latency.
Could that work for the Rasberian build Farm? I would have thought that
for building packages, higher latency storage could be tolerated much
more than for other workloads as most data transfers would be large, so
RAM and CPU performance would be more important.

jz4760 eoma68 card. jz4760 doesn't have SATA... so unless i hear
otherwise i'm going with the JM20329 [because i found a datasheet on
it - hard to find, these!]

some extremely good NAND SSDs that had dual SATA and USB interfaces.
he upgraded a toshiba a100 [ documented it all, including replacing
the screen with a 1280x768] and put a USB-based SSD in, and it
absolutely screams along. because he picked the right part. and
tested a whole bunch.
if you can find him you should be able to ask him, since the
intervening time which is over a year now, how reliable it's been.

1GB of ram is simply unacceptable for an autobuilder nowadays.
After the bad stuff i'm reading about the arndaleboard (apparently
problems even at 1.4 GHz despite the advertised speed being 1.8 GHz) i'm
thinking the 2GB nitrogen6x is the best option right now.
Has anyone here hammered on a nitrogen6x or similar board? is it stable
at the advertised 1GHz with all cores loaded?

Well that's pl2303 based. Those are not known to be the most reliable

things around (and some of the comments in the linux driver are not
encouraging either).
For a reliable working USB serial adapter, something based on FTDI tends
to just work. Most are PL2303 based though since it is much cheaper.
And of course they almost never tell you what they are based on.

pandaboards were not particularry stable when people started using them.

Likewise, using the early kernels with imx5 boards was not a happy
experience.

The price will unfortunately rack up especially for small orders.

I got a 2GB nitrogen6x and have been testing it. It crashed a couple of
times with the first kernel I was using (the one that was included in an
image I got from armhf) but I then upgraded the kernel and it's been
stable since. I also added a heatsink just before I upgraded the kernel
but I don't think that made any difference (it crashed while building
eglibc just before I put the heatsink on, crashed while building eglibc
after I put the heatsink on but before I upgraded the kernel and built
eglibc successfully after upgrading the kernel).
However just as I was becoming reasonablly happy with the nitrogen6x's
stability I happened to notice on twitter that wandboard,org have
released a board with the same basic hardware for about twice the price.
So now I need to get one of those and check it out too...........
