N270 and N330 DC processors

[Alberto Escudero]

Hi,

I am looking for a low power nettop that can host a freeswitch
installation that unfortunately might need to run some Skype clients (CPU
consuming).

Has anyone tested the new Intel Atom Dual Core N330 in comparison with
N270 or N230?

http://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors#.22Diamondville.22_.2845_nm.29_2

I am looking for something under 40W.

There are a few companies integrating now N330: Asus eeePC, MSI... if
anyone was experiences with them... let me know!

if you need really low power, you might wanna consider Z530 based
nettop ? -
we have just had the fit-pc2 out for first tests and are quite happy
with it.

best,

Just happen to have bought an Acer Aspire One with a N270, 1 Gb RAM.
Happy to do any tests you may suggest. I'm pleased with it, but barely
have it for a couple of days...

Cheers,
V.

I will love to benchmark the N270 or the fit-pc2

Any chance I can get r00t access the machines to run a few tests?

Any good tools for CPU benchmarking, David?

For the IP04 and Mesh Potato I work up load tests based on Asterisk.
For example x calls running the most CPU-intensive codec you are likely
to use plus y analog channels with echo can.

[Jeff Wishnie]

At Inveneo we ran 20 extension Asterisk installs on the Via C7 which
is significantly less powerful than the N270

I've used EeeBoxes (N270) as servers for a variety of uses, though not
asterisk or freeswitch.

If you want something nicely packaged, the EeeBox is a good option,
but I don't think there is a N330 version yet.

If you want to try to dual core, there's this pre-built system from
LogicSupply:

Hi Jeff,

I am looking into Dual Core boxes and the release of this...
http://www.ehomeupgrade.com/2009/10/03/asus-eeebox-pc-eb1501/

There is a N330 version, that has no optical CD.

http://www.ehomeupgrade.com/2009/08/31/asus-eeebox-pc-now-sporting-an-intel-atom-n330-processor-and-nvidia-ion-graphics/

Will try to get a couple of units and see how it works out.

[Jeff Wishnie]

Ah, very cool! Glad to see they are upgrading to dual core.

[Ralph Green]

Howdy,
Did you need the cool case of the eeebox? Shuttle makes the X27D with
similar specs and I see it locally for $160. The eeebox has nVidia
graphics, but I don't think that makes much difference for routing
calls.
Good day,
Ralph

[Jeff Wishnie]

NewEgg has it for USD200, still a great price for N330 dual-core.

Thanks for the pointer!

[Jeff Wishnie]

Question on the shuttle--will it run at 12v?

Howdy,
I can't tell. The Shuttle X27D does use an external power brick,
which appears to have only a single voltage output. A good guess would
be 12V. Next time I am in Fry's, I'll look at the box and see if it
says.

In a year, you should be buying Cortex A( Dual core processor machines,
anyway. They will probably be a third the power and a little faster. I
am assuming that call routing does not need floating point, but I don't
really know. That will affect the speed comparison. And, if you want
to get ready for those, the little 99 dollar computers built into a wall
wart would be a good start. Very similar processor, but single core.
Not reliable for production use, but good for tinkering.
Good luck,
Ralph

[Jeff Wishnie]

FYI--The eeebox power supplies put out 18v, but they run fine at 12v...

[Ross Bennetts]

Looks like it is 12v from this:

n0 r00t - machine is traveling too much ;) -

but if we feel it s worth it, we could agree on a benchmark script/set
of params

and run it on our individual machines and share results.

most of these cpu benchmark results exist, though.

best to all,

s.

What about:

http://ark.intel.com/Product.aspx?id=40741
Intel® Atom™ Processor Z550 (512K Cache, 2.00 GHz, 533 MHz FSB)

Alberto: you also have root access to my acer one with the N270 for testing.

let me know if there is anything else we can help with.

Hello,

A question for the Asterisk Dialplan gurus out there. We would like to
add some dialplan to dial a full IP, so we might dial:

10 # 130 # 1 # 144

and then the MP will execute:

Dial(SIP/40...@10.130.1.144)

Anyone know how to do this? I am wondering if AGI is required or if
there is a way to make Asterisk replace the # with . to form the IP so
we can do something like:

Dial(SIP/4000@${EXTEN})

I have worked out how to do a simpler case, where we just dial the last
part of the IP:

exten=> _X!,1,Dial(SIP/40...@10.130.1.${EXTEN})

This works if you dial a 1, 2, or 3 digit number.

Any ideas on how to dial a full IP would be much appreciated.

Thanks,

David

Hello List,

At the 2nd Village Telco workshop we noticed IAX2 calls didn't work on
the MP01, e.g. the call had really messed up audio. I have been
investigating this today. IAX2 is a handy protocol as it can pass
through firewalls easily.

I tried the following IAX2 calls (all GSM codec):

1/ IP04 to MP01 FXS port
2/ IP04 to MP01 "Echo application", this removes the FXS port.
3/ IP04 to Nanostation 2 running Asterisk with an "Echo application".

In all three cases the audio would start breaking up then the loadav
would climb very high (like 35). I see messages on the Asterisk CLI
like:

CLI> [Jan 1 01:28:28] NOTICE[659]: chan_iax2.c:6521 socket_read: Out of
idle IAX2 threads for I/O, pausing!

Googling only finds reference to this problems from 2007, I am still
sorting thru the threads. We are using Asterisk 1.4.11 on the MP01.
This link:

http://lists.digium.com/pipermail/asterisk-bugs/2007-October/004513.html

Suggests it might be fixed in 1.4.12

I have seen a very similar problem when load testing the IP04. Once a
certain number of IAX2 calls are placed (I think it was 8 or 16 calls on
the IP04), some sort of CPU load threshold gets hit and the same
messages occur. SIP tends to handle more calls on the IP04, and doesn't
fall over like IAX2.

So I think IAX2 has sensitivity to CPU load and perhaps delay. In the
tests above it took longer to die with (3) than (1) & (2), probably
because of lower CPU load. The problem doesn't occur on x86 boxes much
as they are much more powerful.

If anyone has experience with this bug pls let me know. Would be nice
to get reliable IAX2 support for the MP01.

Cheers,

David

Hello David

Give this a shot

exten => _X.,1,Set(OCTETS=${EXTEN})

exten => _X.,n,Set(IP=${CUT(OCTETS,#,1)}.${CUT(OCTETS,#,2)}.${CUT(OCTETS,#,3)}.${CUT(OCTETS,#,4)})

exten => _X.,n,Dial(SIP/4000@${IP})

[Ross Bennetts]

FYI,

The general consenus with most Video Conferenceing equipment AFAIK (Tandberg, Polycom, etc) is to use * as the . for dialling IP addresses, rather than #.
I.E. to dial the Tandberg T150 on my desk here, one would usually type 129*180*10*2 into the remote or keypad.
It might be a good idea for us to maintain this defacto standard.

Cheers,
   R...

[Salman Abdul Baset]

On polycoms that I have tried for video conferencing, one can input IP
address using a '.'

I agree that if for some reason, '.' cannot be used, '*' is a better
replacement. # typically indicates end of input for IVRs.

Good Michael!

There is also a possibility with the command System(command | args) from asterisk where you can call a sh script that has access to lot of Linux/Unix functions including the management of characters.

Thanks Michael, that worked great :-)

Ross and Salman, yes I agree we should use * rather than #.
