Those modifications are done via regular Sangoma installation with a special
option to the Setup script.

Thank you for your info Moises.  For those who want to have a high density
system, can you provide what modifications to the Dahdi (or anything else)
do you make?

That is correct, that is our typical load test scenario. However, Asterisk
is a complex system with many features. Our testing focus on SIP to TDM
bridging, meaning the only used applications are Answer() and Dial() with
the DAHDI and SIP channel drivers, typically with latest 1.4.

Additionally we always compile DAHDI modifying the chunk size to reduce the
interrupt load.

As far as your question about PCIe 2.0, yes the A108 should work just fine
there.

While this is too many "eggs" in one basket, but can be useful if you have
"too many" E(T)1s say equivalent to a STM1 (OC3) or more.  In that case, it
would be too many boxes at 8ports / box.

Somewhere in the mailing list, Sangoma devs said that they do 32E(T)1 per
box on the labs quite frequently, although mostly for load testing.

Can asterisk handle that much load (32 E1) on a box?  We have seen asterisk
crash quite frequently with 2 x 4 E1 load on one box (chan_ss7), especially
when the calls per second is above 10.

24 T1 ports, if my math is correct.
Lots of "eggs" for any PC, desktop or not!
Lots of circuits/channels to go South with one machine failure

I would want to spread the load around
But then, it isn't my problem!

Perhaps Sangoma will give similar advice?

i suppose that depends on the number of eggs and baskets you have... but i'm
guessing not many of either since you're considering using a desktop board

[asterisk-users] Sangoma A108 PCIe V2.0

2010-09-17 Thread Anita Hall 
Hi

Does Sangoma 8-port card A108 support PCIe version 2.0 ?

The card is here
http://www.sangoma.com/products/hardware_products/digital_voice_and_data_networking/a108.html

And we want to use 3 such cards in this motherboard because it has 3 PCIe
slots of version 2.0

http://www.intel.com/products/desktop/motherboards/DX58SO/DX58SO-overview.htm

Is this a good idea ? Do you have any experience with multiple A108 with
PCIe on the same motherboard that supports PCIe 2.0 ?

Any comments will be helpful.

Thanks,
Anita Hall
