asterisk users - Aug 2007 - Hardware Platform Recommendations for Digium Card Compatability

Hi there,

Could everyone that has a working production Asterisk server that uses a 
Digium telephony card as a BRI/PRI gateway let me know what 
motherboard/processor your server uses?

We use a Digium TE210P as our telephony card.  We have tried a couple 
motherboards, and neither is giving us satisfactory zttest scores.

The machine we have in production right now is a Biostar U8668-D (VIA 
8237R chipset) with a P4 2.4 GHz, but that system gives regular scores 
barely above the 98% mark, with occasional dips below.  We've tried one 
other board based on an Intel 865 chipset with a 2.8GHz Celeron, and 
that board gives regular 100% marks, with dips down to 95% every 5 
seconds or so, which makes it pretty unusable.

Any help in identifying a better motherboard for Digium cards would be 
appreciated.

Thank you,

Currently running a TE412P in a IBM x3650 Model 7979.  I had some problems
when I also had a TDM400B in the same system.

I have also run this card successfully on a Intel SE7230NH-1 board (having
the TDM400B installed as well was not a problem on this board)

I had a reproduceable kernel panic under moderate load running this board on
a HP DL380G5 with Zaptel 1.4.  Zaptel 1.2 was just fine.

All of my testing was done on CentOS 4.4 and 4.5.

My zttest scores (on the IBM) are generally above 98%, but sometimes I see
the tests start at 97.73% for about 20 seconds before it climbs.  I often
see spikes up to 100% rapidly followed by a drop back to 98.x%.
