[asterisk-users] Is there real benefits on a SMP machine for Asterisk?

[shadowym]

I hope I am not opening a can of worms here but IMHO there is ABSOLUTELY NO REASON TO USE SCSI anymore!  For sure not for this application but most other things too.  SATA is mature now, does command queuing, and works well on 2.6 kernels.  Oh, there is the issue of cost as well.

Raúl,

The short answer is yes, it's better to install Asterisk on a dedicated 
system.  The long answer is that you could probably get away with it, 
but if you have problems you'll be dealing with a lot of variables 
during troubleshooting.  When that time comes, I wouldn't be surprised 
if the first piece of advice people give you is to offload the non-VoIP 
related tasks from the server.

For 35 simultaneous calls, I'd recommend a dedicated server with a 3.0 
GHz dual-core CPU, 2 GB of RAM, and fast SCSI disks.  In my experience, 
the FSB can be just as important as processor speed so keep that in mind 
as you lay out your budget.  You should be able to buy something from 
Dell with redundant power supplies (and other convenient features like a 
remote access controller) for an affordable price.
