Hi all. First of all, thanks a lot for all the answers. They clarified this subject to me.
Anyway, since this seems to be a good (AND cheap) solution in many cases, I decided to ask a bit more in detail: While looking for the motherboards for our 8-12 dual-core-nodes cluster, already with the idea of using on-board dual-Gb ethernets on it, we came across the MSI K9N Ultra and bigger ones family. In this family, there is the MSI K9N Platinum ( http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=730), which is appearing around here at a really affordable price (a bit more than 2 hundred dollars each here). This motherboard uses the nForce 570 MCP chipset from NVidia, and the dual lan bythe Vitesse VSC8601. Here is where our concerns now are held: Basically, is this a good dual Gb lan, good in terms of clustering applications? Has anybody ever used it before, or heard about someone using? Or shall we step back about this specific chip/motherboard? Any help on this subject will be very welcome. Thanks a lot, Jones On 11/14/06, Robin Harker < [EMAIL PROTECTED]> wrote:
ON-board NICS are as good as PCI, so as long as they are Intel or Broadcom don't even think about not using them. AS far as switches are concerned, ignore all layer 3 devices, as you will never use the functionality and go for a cheap as chips layer 2, (non-blocking) from a manufacturer you have heard off, eg: HP, D-Link, SMC or Netgear. If you plan to expand beyong 24 or 48 ports, most now do switches with 10GigE uplinks.

Hi all. Well, I've found some discussions within this list about brands of switches, and some about network card brands also. We came to a question here, in the cluster we are planning: how usefull are the, now so common, onboard gigabit networks (even dual networks) that are shipped in the motherboards? Great, bood, bad or terrible performance? stability issues? Much concern about it's use for clusters? Is there any example, or benchmark available of different onboard network chips in any (cluster?) application?
