[Asterisk-Users] Asterisk Hardware Recommendation

[mattf]

I have never been able to do more than 50 concurrent recordings with Zap ->
SIP phone calls without the audio skipping and/or breaking up. Also, if you
are using Digium TE4XXP and want to do a lot of recording I would recommend
against a SCSI RAID card because of the interrupt conflicts that you will
run into over time. I would recommend a couple of cheaper Asterisk servers
with a dual T1 or Quad T1 board in them and SATA drives, with a nice big
archive server that the audio will be copied to several times a day. Also,
do not record(Monitor) with the 'm' flag on because this will also lead to
more disk read-write while you are already trying to write another 100 or so
streams. Offload the -in and -out files to the archive server and let it
soxmix them together instead. This is the method that we have settled on for
our 12 Asterisk servers and it works rather well for us.

Hi,

I've been reading on the wiki as well as on this list, different 
suggestions of what to look for when designing an asterisk server with 
a lot of traffic. By "a lot" of traffic, I mean a box with a a TE4XXP, 
that will be hit to full capacity (96 simultaneous calls). This box 
will also deliver these calls to SIP users and record all their 
conversations via Monitor.

I've heard that it's not necessarily a matter of memory (RAM) nor the 
need to have a multi-processor machine. But what really matters is that 
the motherboard (architecture) is designed to handle such a high amount 
of interrupts generated by the TE4XXP, the NIC, the storage array 
(whether it's SCSI or IDE or SATA).

Does anyone have experience with particular brands of either 
motherboards they recommend are capable to handle this or complete 
systems (e.g. Dell xxxx or whichever brands), that are ready for this?

Thanks,
Daniel
