Regarding Chipsets/Motherboards. I would stay FAR away from cheap ones. Any chipset/motherboard that electrically and logically separates some PCI slots (ie. interrupts) from onboard peripherals (network controller, VGA, USB etc.) makes compatibility issues with Digium cards much less likely. Many of the newer Intel chipsets do this.
The Xeon chipsets/motherboards are the best IMHO because they usually have PCI-X slots connected directly to the memory controller hub, that you can put your Digium card(s) in, which are completely separate from the peripherals and PCI slots on the I/O controller hub. -----Original Message----- From: Tzafrir Cohen [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 07, 2005 4:59 PM To: [email protected] Subject: Re: [Asterisk-Users] Motherboard and processor recommendations On Wed, Sep 07, 2005 at 11:02:58PM +0300, Soner Tari wrote: > Hi All, > > For sometime now I've been searching the wiki and googling, but I > think I'm missing some of the very important answers.

Would I have problems with all-onboard motherboards (Onboard VGA, > LAN/GLAN, Sound, SATA, RAID) ? I've read the comment about an Onboard > VGA on wiki. Considering the exceptional quality of graphics you'll need with Asterisk, and VGA-compatible adapter would suffice. The on-board one would be more than enough. Ditto for the sound card, at least in most cases. As for the network adapter: Are you going to get anything close to saturating the card? I figure that the efficiency of the network adapter and its driver will not be your bottleneck. Most of the WAN-oriented systems would have worked fine with an old 10Mbps card, probably without a noticable performance hit (right?). So their quality is not much of an issue. If you have the extra space, you can always add an extra one in an expansion slot. But it should not be required. An extra raid controller is something you may consider. But then-again, if it is a cheap software-based raid, it is practically the same as using linux for that (but with more problematic drivers). But it is for you to decide if it is worth the extra cost. > > 2. Which chipset should I prefer: Intel, SiS or VIA? I've read the old > SiS chipset problem on wiki. There is much voodoo about this. There are good and bad boards made with each of those chipsets. In fact, for practically each model of board that has been sold for over a month or so, you'll probably find someone in this list who had bad experience with it. > > 3.

Much transcoding? How many lines? Because if the load on the CPU will be light enough, than the CPU brand won't really matter, you know. > I think this is a very complicated issue, and given so many variables > perhaps luck plays an important part. I figure some people on this list will happily sell you pre-configured systems. Or at least pre-built ones. -- Tzafrir Cohen | [EMAIL PROTECTED] | VIM is http://tzafrir.org.il | | a Mutt's [EMAIL PROTECTED] | | best ICQ# 16849755 | | friend _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
