[Asterisk-Users] How much CPU power needed for asterisk
I'm thinking of placing Asterisk on an itx motherboard in a tiny case. The ITX motherboards top out around 400Mhz PII (in terms of power relative to a desktop). How much CPU would I need for an office of 50 people? How much disk storage for voicemail + OS? (typical / average) The system will have no PCI cards (no Digium FSO/FXO cards) - everything over the LAN connection.

Based on this email, I would tell you that you need to set the CPU to power setting 14, and top the case off with some fresh oil whenever it runs hot. The point is, the quality of the answer depends on the quality of your question, and unfortunately, you didn't provide nearly enough information. - I'd stay away from ITX if your office *depends* on phones. For any professional or semi-professional solution, you should have something with a bit more reliablity and hopefully some redundancy. ITX is built for compact (home-) use. Get a server built for 24/7 operation and keep some spare parts on hand. - What are those 50 people doing in your office? The needs of 50 customer service reps in a call center are much much different from the needs of 50 internal case-workers. What kind of call volume do you expect? - How are you planning on running those 50 office phones? IP phones using sip, h323, etc? ATAs? What codecs? - What kind of WAN connection will you have, and how many calls/channels are you planning on having available? Keep in mind that there's real limit even to a T1 connection, which depends of course on the codec and the connection to your VOIP provider. If T1 is all you got, those 50 folks in the office will most likely not be able to talk at the same time. - Will there be transcoding going on? If so, between which codecs and how many channels at a time? Once you know these things, you'll receive an intelligible answer. If you don't know these things until you have the system up and running, err on the side of over-performing and get dual XEONs with some good ooompf. -----Original Message----- From: Michael Stahl [mailto:mstahl@ocg.ca] Sent: Tuesday, May 17, 2005 1:02 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] How much CPU power needed for asterisk I'm thinking of placing Asterisk on an itx motherboard in a tiny case.

To my knowledge and experience you don't need much CPU power. I don't have Digium card only Sipura-3000 units and when I compile something on Gentoo (CPU usage goes up to 99% and stays there when compiling), when calls comes in on PSTN line and/or I make a call out over IP at the same time, nobody notices any difference in call quality, echo or any other problems; so I don't think you have to worry about CPU power for Asterisk. You will more likely run out of IRQ assignment for your internal cards than CPU power :-) #Joseph On Tue, 2005-05-17 at 14:01 -0400, Michael Stahl wrote:> I'm thinking of placing Asterisk on an itx motherboard in a tiny case. > The ITX motherboards top out around 400Mhz PII (in terms of power > relative to a desktop). > > How much CPU would I need for an office of 50 people?

[Asterisk-Users] How much CPU power needed for asterisk
All, Of course this also depends on the size of the site..... For a large site I would certanly feel more comfortable (and its not that expensive) To use a dual Xeon (64bit proc.-3 Ghz) server platform .........But just as a general rule Linux and asterisk do not demand much CPU utilization but I would take a risk for a large site with a great deal of traffic.....cheers!! Thanks!!
